Acrylonitrile butadiene styrene composites reinforced with nanozirconia and PTFE: Mechanical and thermal behavior
Polymer Composites - Tập 39 Số S3 - 2018
D. Amrishraj, T. Senthilvelan
Acrylonitrile butadiene styrene composites reinforced with varying contents of PTFE and nanozirconia have been prepared by employing twin screw extrusion technique followed by compression molding. Mechanical properties such as hardness, tensile strength, tensile modulus, elongation at break, impact strength, flexural strength, and flexural modulus have been determined by conducting various...... hiện toàn bộ
Processing of microcellular polyester composites
Polymer Composites - Tập 6 Số 3 - Trang 175-180 - 1985
Jae Ryoun Youn, Nam P. Suh
AbstractA new method of producing microcellular polyester composites is developed. The microcellular foam which is produced by supersaturating the polyester resin with nitrogen is cured by dielectric heating. The lightweight composite contains about 10 μm size bubbles. By substituting the microcells for the particulate fillers of the conventional composites, the we...... hiện toàn bộ
Rheological behavior and mechanical properties of PVC/MAP‐POSS nanocomposites
Polymer Composites - Tập 31 Số 10 - Trang 1822-1827 - 2010
Jungang Gao, Yonggang Du, Cuifang Dong
AbstractThe polyhedral oligomeric silsesquioxanes which contains methylacryloylpropyl groups (MAP‐POSS) was synthesized. The MAP‐POSS/PVC nanocomposites were prepared. The influences of composition, shear rate' shear stress on melting rheological behavior of MAP‐POSS/PVC nanocomposites were discussed. The dynamic mechanical properties, mechanical properties, and mo...... hiện toàn bộ
Influence of polyhedral oligomeric silsesquioxanes on thermal and mechanical properties of polycarbonate/POSS hybrid composites
Polymer Composites - Tập 32 Số 9 - Trang 1343-1351 - 2011
Hualun Cai, Kai Xu, H. Liu, X. Liu, Zhiang Fu, M.C. Chen
AbstractTwo types of silsesquioxanes were synthesized by hydrolytic condensation reaction, and then were incorporated into polycarbonate (PC) matrix by melt blending to prepare PC/POSS hybrid composites. The study of morphology of the composites showed that octaphenylsilsesquioxane (PH‐POSS) exhibited partial compatibility with PC matrix, while 3‐glycidyloxypropyls...... hiện toàn bộ
Theory of coalescence in immiscible polymer blends
Polymer Composites - Tập 9 Số 2 - Trang 119-124 - 1988
Ivan Fortelný, Josef Kovář
AbstractThe theory of coalescence in melts of polymer blends was derived on the basis of the Smoluchowski theory for colloid systems. An approximation for a flux of particles used for solutions of colloids in water was analyzed. It is shown that this approximation cannot be used for polymer blends, and an approximation is suggested that could be justifiably used fo...... hiện toàn bộ
Effect of zeolite 5A on the crystalline behavior of polypropylene (PP) in PP/β‐nucleating agent system
Polymer Composites - Tập 29 Số 12 - Trang 1291-1296 - 2008
Zhiping Lv, Caixia Hu, Jianwei Xue, Tao Dou
AbstractThe effect of zeolite 5A on the crystalline behavior of polypropylene (PP) in PP/β‐nucleating agent system was investigated with X‐ray diffractometer (XRD), differential scanning calorimeter (DSC), and polarized light microscope (PLM) in this study. Zeolite 5A has less effect on crystalline phase of PP/β‐nucleating agent than does n... hiện toàn bộ
Effect of carbon nanotube grafting on the wettability and average mechanical properties of carbon fiber/polymer multiscale composites
Polymer Composites - Tập 39 Số S2 - 2018
Harpreet Singh Bedi, Srikant Sekhar Padhee, Prabhat K. Agnihotri
An experimental investigation is performed to relate the wetting behavior of unsized and carbon nanotube (CNT) grafted carbon fibers to the average mechanical properties of unsized and CNT grafted carbon fiber/polymer multiscale composites. Contact angle measurements and single fiber pull out tests show that the choice of polymer matrix plays a crucial role in determining whether the incor...... hiện toàn bộ
Mechanical and electromagnetic interference shielding properties of carbon fiber/graphene nanosheets/epoxy composite
Polymer Composites - Tập 37 Số 8 - Trang 2494-2502 - 2016
Ye Li, Yan Zhao, Jianming Sun, Yue Hao, Jindong Zhang, Xiao Han
Effect of temperature, pressure, and composition on DC resistivity and AC conductivity of conductive styrene–butadiene rubber–particulate metal alloy nanocomposites
Polymer Composites - Tập 28 Số 5 - Trang 696-704 - 2007
G. T. Mohanraj, Pranab Dey, T. K. Chaki, A. K. Chakraborty, Dipak Khastgir
AbstractConductive nanocomposites were prepared using styrene butadiene rubber as the polymer matrix and nanosized powder of copper–nickel (Cu–Ni) alloy as the filler. The filler loading was varied from 0 to 40 phr. The electrical conductivity of filled polymer composites is due to the formation of some continuous conductive networks in the polymer matrix.

Design and evaluation of the interface between carbon nanotubes and natural rubber
Polymer Composites - Tập 32 Số 2 - Trang 236-242 - 2011
Hong‐Xia Jiang, Qing‐Qing Ni, Toshiaki Natsuki
AbstractTo design the interface between carbon nanotubes and natural rubber (NR), a silane coupling agent, bis(3‐triethoxysilylpropyl) tetrasulfide (TESPT), was used to modify the surface of multiwalled carbon nanotubes (MWCNTs) in a two‐step method, and the silane‐modified multiwalled carbon nanotubes (s‐MWCNTs) were combined with NR by solvent casting. The s‐MWCN...... hiện toàn bộ
