EP300L which is a heterophase copolymer. Polymer blends and nanocomposites were prepared by melt compounding method in a twin screw extruder. Nanofil®
5 (N5) and Nanofil®
8(N8) were used as the organoclays, and maleic anhydride grafted polypropylene (M) was used as the compatibilizer. The effects of additive concentrations and types of organoclays on the morphology, mechanical and thermal properties were investigated. Organoclay loading over 2 wt% prevented the intercalation mechanism resulting in large aggregates of clay, thus the material properties became poor even in the presence of compatibilizer. Compatibilizer addition improved the intercalation ability of the polymer, however a substantial increase in mechanical properties was not obtained up to 6 wt % loading of the compatibilizer. XRD analysis revealed that intercalated structures were formed with the addition of compatibilizer and organoclay. The nanocomposites that were prepared with N5 type organoclay showed delaminated structures at 6 wt % compatibilizer loading. v Nanofill ®
5 exhibited the highest improvements in mechanical properties, since the degree of organoclay dispersion was better in Nanofill ®
5 containing nanocomposites in comparison to Nanofill ®
8 containing ones. The DSC analysis indicated a insignificant reduction in the melting temperature of the ternary nanocomposites.

30B were used as organoclays, and ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) and maleic anhydride grafted polypropylene (PP-MAH) were used as compatibilizers. The effects of additive concentrations, types of organoclays and compatibilizers, processing conditions, and the compatibilizer to organoclay ratio on the morphology and mechanical, thermal and flow properties were investigated. Organoclay loading over 2 wt% prevented the intercalation mechanism and material properties, even in the presence of compatibilizer, as a consequence of large clay agglomerate formation. E-MA-GMA compatibilizer improved the intercalation ability of the polymer
however a substantial increase in mechanical properties was not obtained. PP-MAH is found to be a better compatibilizer. Processing conditions significantly affected both mechanical properties and morphology. When the processing temperature was decreased and screw speed was increased simultaneously, tensile and impact properties were improved owing to enhanced shear and dispersive forces. TEM analysis revealed that intercalated and delaminated structures were formed with the addition of PP-MAH compatibilizer. In addition to that, as the ratio of PP-MAH to organoclay was increased, more effective dispersion of organoclay was observed and hence resultant improvements in both tensile and impact properties were greater at compatibilizer to organoclay ratio of three. Cloisite®
15A exhibited the highest improvements in mechanical properties, although the degree of organoclay dispersion was better for Cloisite®
25A and particularly for Cloisite®
30B. Melt flow index values were lower compared to pure recycled polypropylene in the presence of organoclay and compatibilizers. DSC analysis indicated no significant change in the melting behavior of the matrix materials.

s Modulus of PPy/PP composites increased with increasing PPy content, and addition of 2 wt % PPy to PP resulted in a dramatic decrease in the tensile strain at break of the material. Also by addition of 2 wt % PPy to PP, the tensile strength of material decreased and further increase in PPy content, tensile strength increased. Furthermore, an increase in the PPy content in PPy/PP composites resulted in an increase in conductivity. SEM micrographs revealed that as the PPy loading increases from 10% to 20% in composite system, adhered PPy particles by PP matrix were driven out of PP matrix while PP matrix oriented along the draw direction during tensile test.

Повний текст джерелаelectrical conductivities were measured by four probe technique. Since PTP/MMT composites are unprocessable PTP/polypropylene(PP) composites were prepared. Amounts of PTP were changed in the range 2-30 % by weight in the composites. Mechanical properties were investigated by tensile tests. Four probe technique was used for measurement of electrical conductivities. Morphological characterizations were made by SEM. Formation of PTP and its incorporation in PTP/MMT composite were confirmed by FTIR analysis. DSC results showed that PTP does not have any thermal transition in the range 25-300 0C. TGA results showed that PTP/MMT composites have outstanding stability compared to that of PTP. XRD analysis revealed the formation of nanocomposites resulting from intercalation of thiophene in MMT at high MMT contents. Composites were observed as globular particles and clusters in SEM studies. Conductivity values of PTP/MMT composites were in the order of 10-3 S/cm. It is observed that tensile modulus of PTP/PP composites increases by the addition of PTP, but percentage strain at break does not appreciably change. Increasing PTP content increased electrical conductivity.

Resumo: Este trabalho teve como foco principal a obtenção de argilas expandidas por meio da modificação de argila natural com organossilanos, e depois sua incorporação em uma resina de polipropileno em extrusora de rosca dupla para a obtenção de nanocompósitos. As argilas usadas neste estudo foram as argilas montmoriloníticas sódicas Polenita e GelMax, bem como a argila organofílica Viscogel. Os organossilanos empregados no tratamento químico das argilas naturais foram o aminopropiltrimetoxissilano, glicidoxipropiltrietoxissilano e o metacriloxipropiltrietoxissilano. A obtenção da argila expandida foi fortemente influenciada pelas condições reacionais, como tipo e concentração do silano, solvente e pH do meio. As análises de difração de raios X revelaram que os melhores resultados de expansão da argila foram alcançados ao usar o silano aminopropiltrimetoxissilano em meio aquoso na faixa de pH entre 8 e 10. Segundo os dados de análise térmica, esta argila apresentou uma estabilidada térmica bem superior às tradicionais argilas organofílicas. Antes da incorporação da argila à matriz de polipropileno, primeiramente fez-se um estudo de otimização das condições de mistura, usando-se para isto a argila organofílica Viscogel, de elevado espaçamento basal. Desenvolveu-se um perfil de rosca com alta taxa de cisalhamento, no qual foi obtido um nanocompósito com dispersão de tamanho das lamelas da argila entre 5 a 15 nm. Tal dispersão resultou em ganho nas propriedades mecânicas em torno de 30 % em relação ao polipropileno puro. Este perfil de rosca foi, portanto, utilizado para realizar o processamento do polipropileno com a nova argila expandida. A partir dos resultados de difração de raios X e de microscopia eletrônica de transmissão, concluiu-se que não foi possível delaminar totalmente esta argila no polímero, como observado para a argila organofílica. Porém, os resultados relativos às propriedades mecânicas dos materiais obtidos mostraram que a argila modificada com aminopropiltrimetoxis-silano apresentou propriedades semelhantes às da argila organofílica, indicando que apesar do menor grau de dispersão, estas propriedades foram favorecidas pela maior interação entre a argila modificada e a matriz polimérica
Abstract: The purpose of this work was to obtain expanded clay by modifying clay with organosilane, and its incorporation into polypropylene resin to prepare a polypro-pylene-clay nanocomposite. Natural sodium montmorillonite (GelMax, Polenita) as well as organophylic clay (Viscogel ED) were used for this purpose. Three types of silanes were used to modify the clay: Aminopropyltrimethoxysilane (APS), glyci-doxypropyltriethoxysilane (GPS) and methacryloxypropyltrimethoxysilane (MPS). The expanded clay was strongly affected by reaction conditions, such as silane type and concentration, solvent and pH. According to XRD analysis, the higher basal distance was achieved in aqueous dispersion (pH 8-10) using the APS as a modifier. Modified clay showed superior thermal stability in comparison to organo-phylic clay, using thermogravimetric analysis. Besides the clay modification pro-cess, the screw profile influence on nanocomposite properties was also evaluated. An organophylic clay (Viscogel) was used to optimize the extrusion conditions, in this study. The composite processing was carried out in a twin screw extruder with higher shear screw profile. In this way, an exfoliated nanocomposite was obtained, where the clay layer thickness was between 5 and 15 nm. The flexural modulus of such nanocomposite was 30% higher than virgin polypropylene. This higher shear screw profile was used to extrude the polypropylene/aminopropylsilane-modified clay. Based on the X-ray diffraction and transmission electron microscopy results, a satisfactory exfoliation degree for silane-modified clay was not achieved, as observed for organophylic clay. In spite of the low exfoliation level of silane-modi-fied clay, the mechanical properties of its composite were similar to the organo-phylic clay based nanocomposite. This fact was attributed to better adhesion between polypropylene-silane modified clay than the polypropylene-organophylic clay system
