聚电解质凝胶的体积相变：离子大小的效应
关键字：聚电解质凝胶，相变，Flory-Rehner-Tanaka 理论
人们对于聚电解质凝胶的体积转变已经理解得很清楚了，但是以往的理论都是将小离子视作点电荷，对小离子的大小的效应尚不曾涉及。本文将 Tanaka 的经典理论推广到离子有一定体积的情形，系统研究离子大小对聚电解质凝聚相变的影响。在没有外加盐情况下，当反离子体积比较小时，聚电解质凝胶的体积相变是不连续转变，当反离子体积比较大时，聚电解质凝胶的体积转变变为连续相变。当有外加盐加入时，外加盐浓度逐渐增大也会...

超高分子量聚乙烯共混物的亚稳态在其加工成型中的应用
关键字：：UHMWPE,耗散粒子动力学理论,Flory-Huggins 理论
超高分子量聚乙烯（UHMWPE）是一种综合性能优异的热塑性塑料。然而极高的分子量使其熔体粘度高达108Pa.s，不能通过普通连续成型工艺加工。

嵌段共聚物与相应均聚物溶液的热力学行为比较
关键字：嵌段共聚物；分子结构；Flory-Huggins 相互作用参数；拟合
嵌段共聚物浓溶液中存在广泛的微相分离，因而正确理解其热力学行为在应用或理论领域显得尤为重要。本工作采用蒸气压测定和光散射法获得线形两嵌段（SB）、线形三嵌段〔(SB)2〕和星形四臂三嵌段〔(SB)4〕的苯乙烯－丁二烯嵌段共聚物（SBS）与溶剂四氢呋喃(THF)间的相互作用参数(χ)，温度范围为25 至55 ℃。

关键字：ATRP; six-arm copolymers; monomer reactivity ratios; self-assembly; salt effect.
A series of star-shaped poly(ε-caprolactone) (PCL)-based diblock and triblock copolymerscontaining 2-(Dimethylamino)ethyl methacrylate (DMAEMA or DMA) and oligo(ethylene glycol)monomethyl ether methacrylate (OEGMA or OEG) were synthesized in one pot by atom transfer radical polymerization (ATRP) using a six-arm PCL-based macroinitiator. The precursor and the resultant copolymers were chara...

Research on the Micro-Structural Evolution of Phenol-Formaldehyde Resin Modified by Boron Carbide
关键字：Phenol-Formaldehyde Resin Modified, Boron Carbide
Phenol-formaldehyde (PF) resin usually could not be applied in the high-temperature environments due to its poor heat-resistance. Many kinds of modification methods had been presented in order to improve its stability of the structures...
