Full textTra i processi per la produzione di componenti micro e nano strutturati, il processo di micro stampaggio a iniezione presenta una serie di vantaggi che lo rendono commercialmente interessante. Tale tecnologia è caratterizzata da un elevato grado di riproducibilità, che la rende idonea alla produzione di massa di micro componenti in materiale termoplastico. Parlando di micro prodotti, la qualità del pezzo stampato risulta essere di fondamentale importanza e per questo, negli ultimi decenni, lo studio dei fattori che influenzano la qualità del prodotto finito, sono stati al centro di numerose indagini. Questo lavoro di tesi si pone come obbiettivo l'analisi del processo di micro stampaggio per la produzione di componenti micro e nano strutturati aventi features ad elevato rapporto di forma. Lo studio si concentra soprattutto sulle limitazioni del processo, utilizzando come casi studio delle geometrie particolarmente critiche per il micro stampaggio a iniezione. La caratterizzazione del processo e l'individuazione dei sui limiti sono stati indagati non solo considerando i parametri che influenzano la qualità del prodotto finito, ma anche le proprietà dei materiali termoplastici impiegati, l'interazione tra materiale plastico e stampo, e l'utilizzo di tecnologie ausiliarie come il riscaldamento e raffreddamento rapido dello stampo e l'evacuazione forzata dell'aria dalla cavità. I risultati confermano quanto riportato in letteratura e contribuiscono ad estendere lo stato dell'arte sul processo di micro stampaggio a iniezione, il quale rappresenta ad oggi una tecnologia affidabile ed economicamente efficace per la produzione su larga scala di micro componenti in materiale plastico in diversi settori industriali.

A rapid, cost-effective and high-throughput process for nanotexturing subwavelength structures with high uniformity using the polycarbonate (PC) is realized via injection nanomolding. The process enables the precise control of nanohole array (NHA) surface topography (nanohole depth, diameter, and periodicity) over large areas thereby presenting a highly versatile platform for fabricating substrates with user-defined, functional performance. Specifically, the optical property of the PC substrates were systematically characterized and tuned through the modulation of the depths of NHA. The aspect ratio submicron holes can be easily modulated and experimentally proven by simply adjusting the molding temperature. The nanotextured depths were reliably fabricated in the range of 200 to 400 nm with a period of approximately 700 nm. The fabricated PC films can reduce the reflectivity from an original bare film of 10.2% and 8.9% to 1.4% and 2.1% with 400-nm depth of nanoholes at the wavelength of 400 and 550 nm, respectively. Compared with conventional moth-like nanostructures with nanopillar arrays with heights adjustable only by an etching process, this paper proposes a facile route with submicron holes to achieve a similar antireflective function, with a significantly reduced time and facile height modulation capability. Furthermore, the effects of multilayer coatings of dielectric and metallic layers on the nanomolded NHA have been performed and potential sensing application is explored.

In this research, molecular dynamics simulation is adopted to simulate the molding filling in nano-injection molding process. Our work divided into two parts is as follows. (I) Glass transition temperature : Molecular dynamics is adopted to simulate the glass transition temperature of polypropylene at different chain length, and the chain length has 200, 400 and 800 , respectively. The simulated purpose is to explore the relation between the chain length(molecular weight) of polymer and the glass transition temperature of polymer. (II) We adopt molecular dynamics to simulate the nano-scale injection molding process, and investigate the defects during molding filling process. With decreasing the injection velocity, the adsorption phenomena at the entrance of mold will become more obvious. The orientation of polymer is obvious at the wall of runner and the wall which faces the entrance of mold. While the temperature of system at 350 K, polymer has less tendency to adsorb on the wall.

The miniaturization of components and systems has been progressing rapidly due to the developments in microelectronics, communication, optoelectronics, and biotechnology. Recently, the use of plastic material is becoming a potential alternative due to its versatile property and ease of batch fabrication. Most micro parts, such as gears and fans, need a strong structural capability to resist abrasive. Only plastic material cannot satisfy this requirement. Fillers or fibers are tried to add into plastic compounds to enforce structural strength. But, compounds and reinforced plastics have not been used successfully in the micro moulding process. Thus, the nano-particles were introduced into plastic to enforce structural strength and improve filling properties. This thesis studied the processing and wearing properties of nano-composites. The filling and wear properties of nano-materials, SiO2, TiO2, and ZnO with 10%, 20%, and 30% weight content, respectively, introduced to PP were tested. The processing characteristics of a mold with 4 cavities and an IC micro-structure were observed. Experimental results show that the shrinkage of micro-parts with high pressure, impact velocity, cooling rate was significantly reduced. However, the shrinkage was slightly increased when mold temperature was promoted. The shrinkage was decreased as nano-particle contents were increased. The nano-composite with 30% SiO2 reduced 55% in shrinkage compared to pure PP. The filling properties of IC micro-structure using ZnO nano-materials had an outstanding result. The filling properties of nano-material with 10% nano-particles were better than those of 20% and 30% nano-particles contents. However, the filling property was worse when POM with bigger particles was introduced. The hardness of nano-composites was increased as the weight content in PP was increased. The nano-material with 30% SiO2 promoted 24% in hardness compared to pure PP. However, wear resistance was decreased as the nano-material content was increased in SiO2 and TiO2. But wear resistance was slightly promoted when ZnO particles were used. From TGA testing, the decomposition was increased and serious in SiO2 and TiO2 resulting melting temperature was decreased. The decomposition was reduced in ZnO resulting the melt temperature was not decreased. The results show that the filling properties were outstanding when nano-particles were introduced into plastic pellets. The wear resistance was reduced if not suitable nano-materials were chosen.

In this research, molecular dynamics simulation is adopted to simulate the glass transition temperature of polyethlene and the molding filling in nano-injection molding process. Our work divided into two parts is as follows. I. Glass transition temperature：Molecular dynamics is adopted to simulate the glass transition temperature of polymer at different chain lengths, and the chain lengths are 100,200,400 and 800, respectively. The purpose of the simulation is to explore not only the relation between the chain length and the glass transition temperature of polymer, but also the relation between the pressure and the glass transition temperature of polymer at the same chain length. II. Unsteady nano injection molding：With increasing chain length, the density of local system gets more uniform.The probability of warpage becomes great with increasing the interaction between metal particle and polymer particle. Besides, the simulation results between Pt and Au are almost the same. However, if the injection velocity is too large, more plastics will be wasted and the filling quality is relatively bad. Finally, when the temperature is on the increase, the polymer gets easier to be processed and the density in the mold gets more uniform.

In recent years, there is a considerable development in technique which has been a tempting trend of miniaturization in production technology and the techniques which demands the quality and structures which face the role in nanotechnology. In this study, molding of nano-and micro-features using injection and imprint technique is focused. A square, silicon grating in a 3x3 mm2 array, with a depth of 82 nm 1.5µm 0.9µm, and a pitch of 3.0µm. The grating costs only about NT 4000. It provides a simple way to replicate high quality nano-scale molded parts by using a simple custom-made injection machine and hot embossing machine results in manufacturing the different shape and the structure depth nano-and micro-features part. In the injection molding process, nano-and micron structures will be masked in the mold inserts molds with a simple silicon dye using the assist of simple custom-made injection machine. In this technique polymethylmethacrylate (PMMA) and polycarbonate (PC) act as the nano-micro-features. In the analysis the depth of 82 nm and 0.9 μm can be produced by the micro-structural formability. It is a low-cost and fast way to successfully produce high-precision nano-and micro structural elements. The results shows that, when the simple mold and custom-made machine were employed, structure is encountered with the nano-micron micro-structure shape, by improve the mold temperature and injection pressure, which can be a clear edge and the surface of a higher quality. Generally in the press printing process, nano-micro-features structure can be produced 82 nm, 1.5 μm and 0.9 μm can be obtained. An optical film of PMMA and PC is used in molding experiments. The depth of 82 nm, 1.5 μm and 0.9 μm can be produced by the micro-structural formability. To identify the glass transition temperature thermal analysis instruments were used to control the parameters as a reference. For a silicone mold-jet we required the imprinted molding window. A single parameter method is used to investigate the dye temperature imprints pressure, imprint time and ejection temperature of nano and micro-structure for the surface roughness and shape effects. The result shows that, forming a high pressure and imprinted with the injection temperature is linear. If the Injection temperature is closer to the glass transition temperature, will be difficult to form the shapes and also affects the roughness of the most significant process parameters in the ejection temperature. To investigate the surface morphology of the obtained micron-sized structures we require Chanai electron microscopy. Further to make the measurements of height and surface roughness of the samples we use atomic force microscope (AFM), Chennai-micron structure of its.

Nano and micro technology is attracting more attention and has increasing applications in recent years. Among the products with applications of nano technology, many of them are made of polymer plastics. Micro injection molding is one of the important processes for polymer plastics. In micro injection molding, the ability for the polymer melt to flow into the micro/nano features is a crucial factor for successful molding. The flow behavior of polymer in micro/nano features needs to be explored further to facilitate the molding process. In this study, we investigated the effects of the processing conditions on the filling of micro/nano features analytically and experimentally. Firstly, mold inserts with micro or nano features were constructed by LIGA-LIKE process. Secondly, an analytical model was developed to model the filling of polymer melt in the micro/nano features. Molding experiments were performed to verify the analytical filling model. With this verified model, a theoretical filling distance can be predicted for the micro/nano injection molding, and the suitable processing conditions can be estimated for different geometries of product. Finally, the Infrared heating system is introduced to improve the penetration distance in nano feature filling.
