Synthesis of High Performance Composite Materials by using Charge transfer interaction and Their Mechanical Properties

在这项研究中，我们的注意力集中在一对具有吸引力的相互作用的聚合物上，例如库仑和电荷转移相互作用。1，3，5-三嗪聚合物和硝化聚苯乙烯(NPS)分别作为电子供体聚合物和电子受体聚合物。研究了NPS在这些复合材料中的分散性与其力学性能的关系。(1)以6-二丁氨基-1，3，5-三氮-2，4-二硫醇和α，α‘-二溴对二甲苯或1，6-二溴正己烷为原料，在相转移催化剂作用下进行两相缩聚反应，可制得高相对分子质量的1，3，5-三嗪类聚合物(PTX)和高分子量的PTH。(PTX/NPS)复合膜比(PTH/NPS)复合膜更透明，这是因为PTX与NPS具有更好的相容性。聚苯乙烯的硝化改善了PTX或PTH与NPS的相容性，提高了它们的拉伸强度。(3)与PTH膜相比，NPS的加入使PTX膜的力学性能有了较大的提高。

In this study, Our attention has been focused on a pair of polymers having attractive interaction such as coulombic and charge transfer interactions. 1,3,5-triazine-containing polymers and nitrated poly(styrene)(NPS) were used as electron-donor polymers and electron-acceptor polymers, respectively. The relationship between dispersion of NPS in these composites and their mechanical properties was investigated. The following results could be obtained in this study.(1) 1,3,5-Triazine-containing polymers(PTX) and (PTH) with high molecular weights could be prepared from 6-dibutylamino-1,3,5-triazine-2,4-dithiol and α, α'-dibromo-p-xylene or 1,6-dibromo-n-hexane by the two phase polycondensation reaction with phase transfer catalyst, respectively.(2) The composites of (PTX) or (PTH) with poly(styrene) having various nitro group content could be obtained by the solution blend in chloroform. (PTX/NPS)composite films were more transparent than (PTH/NPS)composite films because of better miscibility between PTX and NPS. Nitration of poly(styrene) improved miscibility between PTX or PTH and NPS, which enhanced their tensile strength.(3) Mechanical properties of the PTX films were greatly improved by blending with NPS in comparison with those of the PTH films.
