[Composites Part A: Applied Science and Manufacturing] Simultaneous improvement of thermal conductivities and electromagnetic interference shielding performances in polystyrene composites via constructing interconnection oriented networks based on electrospinning technology
Abstract: Polymer composites with dual functions of thermal conductivity and electromagnetic interference (EMI) shielding are hardly reported. Herein, we fabricated polystyrene (PS) based composites containing interconnection oriented graphite nanoplatelets (GNPs) by the combining method of electrospinning, cold-pressing followed by hot-pressing. In-plane thermal conductivity (λ//) and total SE...

【Composites Science and Technology】Critical rubber layer thickness of core-shell particles with a rigid core and a soft shell for toughening of epoxy resins without loss of elastic modulus and strength
Abstract:
Core-shell particles with a rigid silica core and a poly(butyl acrylate) (PBA) rubber shell are used to toughen epoxy resins without loss of elastic modulus and tensile strength. Both the diameter of silica core (D) and thickness of PBA shell (Ts) of silica-PBA core-shell particles are accurately controlled by sol-gel synthesis and seed emulsion polymerization process, respect...

[Journal of Materials Chemistry C]Significantly Enhanced and Precisely Modeled Thermal Conductivity in Polyimide Nanocomposites by Chemically Modified Graphene via in-situ Polymerization and Electrospinning-hot press Technology
Both aminopropylisobutyl polyhedral oligomeric silsesquioxane (NH2-POSS) and hydrazine monohydrate were utilized to functionalize graphene oxide (GO), and to obtain chemically modified graphene (CMG), which was then used for preparing thermally conductive CMG/polyimide (CMG/PI) nanocomposites via a sequential in situpolymerization and electrospinning-hot press technology. NH2-POSS molecules were...

76. Investigation of the free volume properties in nylon 6/carbon nanotubes nanocomposites by positron annihilation technology. D.H.Yu,B.Wang,T.X.Liu. Chin.Polym.Bull.(高分子通报), 9, 56-61, 2006.
采用正电子湮没寿命谱技术研究了尼龙6/碳纳米管纳米复合材料的自由体积特性.实验结果发现碳纳米管对纳米复合材料的自由体积孔洞尺寸影响甚微,而自由体积孔洞数目和相对自由体积分数均随碳纳米管含量的增加而明显减小.导致这种减小的原因可能来自两方面,其一是由于碳纳米管和基质聚合物间的相互作用限制了高分子链段运动;其二是碳纳米管填充增强了尼龙6基体结晶性能.此外,力学性能研究表明,碳纳米管在复合材料中较均匀的分散和较好...
