Since 1991, 1D nanostructures of carbon material - carbon nanotubes were discovered, low dimensional nanomaterials have attracted lots of attention in the past few decades. Hexagonal boron nitride , with a structure and properties similar to graphite, are expected to be the potential nanomaterials for several applications because of its excellent properties, such as high thermal conductivity, high thermal stability, high energy gap, high mechanical strength and low friction coefficient, etc. However, irreversible agglomeration and stacking of these materials always happened, which would reduce its active surface area and limit its practical applications. Thus, finding an efficient method to exfoliate the hexagonal boron nitride materials has been focused in the recent years. Here, we report a green method of thermal exfoliation hexagonal boron nitride nanosheets, without any surfactant or organic solvent. The characterizations show no special functional groups in IR analysis, no change in crystal type in boron nitride nanosheets compared with those in original boron nitride powder. A pure BNNs aqueous solution about concentration 50 ppm has been measured, and the solution can maintain stability about 1 month, with BNNs average thickness about 13 nm, average diameter 200±62 nm as the final result. We believe that this method will be important for obtaining boron nitride nanosheets with monolayer or only few layers which will be significant for gas storage applications such as methane.

It was since 2004 that Prof. Andre Geim and Dr. Konstantin Novoselov used mechanical exfoliation method to gain monolayered graphite ---graphene. They have found it has significant electronic behavior and mechanical strength, and opened a route to study the optical and electric behaviors and application of few layered inorganic materials. This study focus on the synthesis of BCN nanosheets via chemical decoration of graphene oxide, hydrothermal exfoliations of boron nitride with the aid of hydrogen peroxide, and the synthesis of few layered structure of molybdenum disulfide by CVD process. In Chapter 1, it is about the basic structure, characteristics and recently progress of graphene, boron carbonitride, boron nitride and molybdenum disulfide nanosheets. In Chapter 2, it is about the experimental sections and investigating instrument. Chapter 3 is about the synthesis of BCN nanosheets, we have successfully doped GO nanosheets with BN via partial substitution of carbon atoms in graphene by boron and nitrogen atoms. Based on the XPS data, the doping concentration of BN increases with the increasing of the reaction temperature. Furthermore, we found that the use of gaseous ammonia allows the doping of graphene allows the doping of graphene with BN to be carried out at the lower temperature. The Raman spectra of the BCN sample synthesized at the various temperatures showed that I(D)/I(G) ratio is proportional to the doping concentration of BN in graphene. Furthermore, the estimate value of graphene nanocrystallite size decreases with the increase in the degree of doping in graphene. Finally, UV spectra of BCN sample with various doping concentration of BN have verified that the band gap of graphene is opened and dependent on atomic composition in nanosheets. For the electrical measurements, we will fabricate the bottom gated field-effect transistors by using the BN-doped graphene. For the studies of BN domain distribution in graphene, we will characterize the BCN samples by using electron energy loss spectroscopy. It is expected that the difference in current between graphene and BN domain can be observed. Chapter 4 is the synthesis of BN nanosheets, we have succesfully decorate BN with OH group via hydrothermal reactions with hydrogen peroxide, and sequentially exfoliated via sonication to gain BN nanosheets. Based on the AFM data, lateral size and height of BN nanosheets decreaes with increasing the reaction temperature.UV spectra of BN nanosheets have verified increased solubility with increased OH group . Finally, we use BN nanosheets to absorb perylene-3,4,9,10-tetracarboxylic acid tetrapotassium salt (PTAS) molecule with π-π interaction and desorption with KOH. We found that with the increase of OH concentration desorption concentration decreases caused by blocking of OH group. Chapter 5 is the synthesis of MoS2 layered structure, large-area MoS2 films are directly synthesized on SiO2/Si substrates with chemical vapor deposition. It is noteworthy that the growth of MoS2 is not unique to SiO2 substrates and it is also observed on other insulating substrates such as sapphire. The as-synthesized films are consisted of monolayer, bilayer and other few-layer MoS2. Chemical configurations, including stoichiometry and valence states of MoS2 layers are confirmed with XPS. Raman spectra and PL performance of the monolayer MoS2 are presented. TEM and SAED demonstrate that the monolayer MoS2 exhibits six-fold symmetry hexagonal lattice and high crystallinity. The electric measurement for the bottom-gate transistor shows a N-type semiconductor behavior and the on-off current ratio is approximately 1 x 104. The seeding approach can be further used to grow other transition metal dichalcogenides. Finally, Chapter 6 is the conclusion and future work.

This research is expect to synthesize large area of hexagonal boron nitride on flexible substrate under low temperature , and by using the hexagonal BN which has the property of high exciton binding energy, various nanostructures, and wide band gap to replace the organic light-emitting layer of OLED. Our experiment was carried out in very high frequency plasma enhanced chemical vapor deposition system with quartz tube enhanced plasma density, synthesized boron nitride nanosheets on aluminum foil. Our research also analyzed the morphology, structure, growth process and Luminescent properties of hexagonal boron nitride nanosheets by SEM, FTIR, Raman and PL spectrum. Using the experiment conditions of electrode distance 1.5cm, process pressure 0.5torr, Ar 50sccm, N2 50sccm, B2H6 50sccm, and RF power 150W, our hexagonal BN nanosheets with thickness 500nm on Si wafer substrate not only get the larger area than other conditions, but also stronger FTIR and Raman spectrum signals. Hence, we think the condition to produce larger morphology of hexagonal BN nanosheets need orderly hexagonal BN structure. Besides, we successfully synthesized hexagonal BN nanosheets on flexible substrate, but the morphology is smaller than the one produced on Si wafer substrate. We think it may attribute to the lattice structure of Si wafer is better for hexagonal BN to deposition. In this study, our hexagonal BN nanosheets have the property of ultraviolet luminescent with wavelength 305nm to 395nm investigated by PL spectrum. But the peak that reference mentioned was 215nm. We guess the difference with our result is because the structural defects in our V samples. We want to apply our hexagonal BN nanosheets to the application of far ultraviolet light emitting device, but the process needed to be improved to get the better structure of the hexagonal BN nanosheets and without the influence of substrate structure. We think this is the primary problem needed to solve in the future research.

In this study, the layers of hexagonal boron nitride (h-BN) were stripped by chemical intercalation and free radical polymerization to prepare boron nitride nanosheets (BNNSs) to solve the current preparation of boron nitride nanosheets. The size of the nano tablets cannot be controlled, the process is complicated, and the like, and the achieve size control and the process are simple. The h-BN, BNNSs and spherical alumina (Al2O3) were applied to the filling of the silicone rubber to prepare the Thermal Conductive Pad. The difference between the thermal conductivity and the mechanical properties of the single and composite particles was discussed. The optimal parameters design of BNNSs preparation, thermal conductivity silicone pad preparation and thermal conductivity silicone pad experiment are discussed in three parts. The method of composite particles and filled nanofiller is used to solve the problem of limited thermal conductivity of single filler. In the state, the thermal conductive rubber pad can have the purpose of high thermal conductivity and high mechanical properties. The first part is the preparation of boron nitride nanosheets. The raw material composition is h-BN, and the intercalation agent dimethyl acrylamide (DMAA) provides ammonium salt ions for intercalation. The Azobisisobutyronitrile (AIBN) initiates a radical polymerization reaction with the intercalation agent in a thermal environment to promote molecular growth and achieve the effect of exfoliation. XRD and FE-TEM were used to analyze the interlayer distance and crystal structure of BNNSs. FE-SEM analysis of BNNSs sheet thickness, the results show that adding AIBN 0.1 phr, reaction time of 24 hours, interlayer distance of up to 0.35 nm, sheet thickness of 5 nm, and BNNSs chemical intercalation After the peeling, its crystal structure was not destroyed. The second part is the preparation of a thermal conductive rubber pad. The first part of BNNSs was filled into ruthenium rubber to prove the high thermal conductivity of BNNSs. The experimental results confirmed that single-filled BNNSs can improve the thermal conductivity and mechanical properties of silicone rubber more than h-BN. Therefore, Al2O3 was added in this study. The method of composite particles is used to prepare a thermal conductive silicone pad of composite particles, which solves the problem of improving the thermal conductivity of a single filler. The results show that 60% by weight of Al2O3 and 20% by weight of BNNSs, thermal conductivity and tensile strength of 5.23 W/mK and 102 Psi, respectively, confirm that the thermal conductive mat prepared in this study is It can combine high thermal conductivity and high mechanical properties under the condition of reducing the powder filling amount. The third part is the optimization parameter design and experimental analysis of the thermal conductive silicone pad process. The Taguchi method and the Elimination et selection translating reality (ELECTRE) are used for experimental planning, and the number of complicated experiments and the cost is reduced to the minimum. The influence of each control factor on the quality characteristics of the thermal pad is discussed. The combination of the optimized process parameters is found, and the physical properties of the thermal pad are measured. The thermal conductivity and tensile properties of the thermal pad are measured. 5.14 W/mK and 102 Psi. It is confirmed that the filling of BNNSs can effectively improve the thermal conductivity and mechanical properties, and meet the demand specification for the use of commercially available thermal conductive silicone pads.
