主链型芳香族聚合物的研究进展

主链型芳香族聚合物具有热稳定性高，化学稳定性好、质地轻且牢固以及良好的加工成型性等优点，然而芳香族聚合物的应用受到芳香单体制备的限制，煤中富含合成聚合物所需的芳香单体。因此，由煤制“特异化学品”应当成为煤化工未来发展的重要方向，这为煤的非燃料利用提供了新的途径。     

不同表面上的纳米微米层导电聚合物

从本质上说，人们大约在30年前发现了导电聚合物（ICP），但只是在过去的十年来它们的用途才被广泛地开发出来。本文讨论导电聚合物的性能和应用，主要是讨论了聚吡咯沉积在不同基体上的情况。通过在基体如纺织品上涂覆一薄层导电聚合物，产品能够避免许多纯导电聚合物的加工问题。例如，如果在织物上涂覆一层导电聚合物，就能得到坚固、柔韧、弹性较大的易加工导电材料。薄层涂覆物没有改变基础材料的机械性能。

当前导电炭黑性能与纯度的进展

炭黑是最常用的导电添加剂。导电的添加剂加入绝缘聚合物基体后，能在特定的体积浓度闽值下生成一个导电网络。炭黑和聚合物的特征共同决定了这个临界浓度。开发新型导电炭黑的主要任务就是降低此突增界限。与其它导电添加剂相比，导电炭黑具有很显著的优点，因为它和聚合物有相容性，对聚合物机械性能的影响较小。

A study of pyridinium‐type functional polymers. IV. Behavioral features of the antibacterial activity of insoluble pyridinium‐type polymers

The antibacterial activity of insoluble pyridinium‐type polymers with different structures against Escherichia coli suspended in sterilized and distilled water was investigated by a colony count method. The results show that the antibacterial activity of insoluble pyridinium‐type polymers, except for one containing I⁻, is characterized by an ability to capture bacterial cells in a living state by adsorption or adhesion, with the process of capturing bacterial cells being at least partially irreversible. This feature differs from the antibacterial activity of the corresponding soluble polymers, which is characterized by the ability to kill bacterial cells in water. In addition, insoluble pyridinium‐type polymers can also capture dead bacterial cells. This implies that insoluble pyridinium‐type polymers possess broad prospects for development in new water treatment techniques and whole‐cell immobilization techniques. © 2000 John Wiley & Sons, Inc.

Review of electronic and optical properties of semiconducting π‐conjugated polymers: applications in optoelectronics

A general overview of the optoelectronic properties of π‐conjugated polymers is presented. Two types of polymer are discerned: interchangeable structures of the same energy (degenerate), such as polyacetylene; and non‐degenerate polymers, such as poly(para‐phenylene). The band structures of degenerate and non‐degenerate polymers are related to their conductivities in doped and non‐doped states. In both cases, disorder and impurities play an important role in conductivity. Polarons, bipolarons and excitons are detailed with respect to doping and charge transfers. Given the fibrillic nature of these materials, the variable range hopping (VRH) law for semiconducting polymers is modified to account for metallic behaviours. Optoelectronic properties—electroluminescence and photovoltaic activity—are explained in terms of HOMO and LUMO bands, polaron‐exciton and charge movement over one or more molecules. The properties of H‐ or J‐type aggregates and their effects on transitions are related to target applications. Device structures of polymer light‐emitting diodes are explicitly linked to optimising polaron recombinations and overall quantum efficiencies. The particularly promising use of π‐conjugated polymers in photovoltaic devices is discussed. Copyright © 2004 Society of Chemical Industry

Intrinsic high refractive index polymers

As the ubiquity and complexity of optical devices grows, our technology becomes more dependent on specialized functional materials. One area of continued interest is in high refractive index polymers as lightweight, processable and inexpensive alternatives to silicon and glass. In addition to a high refractive index, optical applications require these polymers to be transparent and have a low optical dispersion. Both nanocomposite and intrinsic high refractive index polymers offer particular advantages and disadvantages. While nanocomposite high refractive index polymers have refractive indices above 1.80, the nanoparticle type, content and size can negatively affect storage stability and processability. Alternatively, intrinsic high refractive index polymers are prepared by introducing an atom or substituent with a high molar refraction into a polymer chain; the resultant polymers are easier to store, transport, tune and process. Polymers containing aromatic groups, halogens (except fluorine), phosphorus, silicon, fullerenes and organometallic moieties have all shown significant promise. Many factors can affect intrinsic high refractive index polymer performance including molecular packing, molar volume, chain flexibility and substituent content. This mini‐review summarizes the principles behind and recent developments in intrinsic high refractive index polymers. © 2014 Society of Chemical Industry     

A study of pyridinium‐type functional polymers. III. Preparation and characterization of insoluble pyridinium‐type polymers

The copolymers of 4‐vinylpyridine (4VP), styrene (St) and divinylbenzene (DVB) with varied compositions, P(4VP‐St‐DVB), were synthesized by suspension polymerization using 2,2′‐azobisisobutyronitrile (AIBN) as an initiator. The insoluble (crosslinked) pyridinium‐type polymers in benzyl–pyridinium bromide form, which possess various macromolecular chain compositions, were prepared by the reaction of each P(4VP‐St‐DVB) with benzyl bromide (BzBr), respectively. By using different halohydrocarbon RX in the quaternization of P(4VP‐St‐DVB), the insoluble pyridinium‐type polymers with various pyridinium group structures were obtained. The structures of P(4VP‐St‐DVB) and its quaternized product Q‐P(4VP‐St‐DVB) were identified by FTIR. The 4VP content in each copolymer P(4VP‐St‐DVB) was measured by nonaqueous titration; and the pyridinium group content (C_q) in each Q‐P(4VP‐St‐DVB) sample was determined by means of the back titration manner in argentometry and/or the elemental analysis method, respectively. In addition, the particle structure and the surface morphology of the thus‐prepared polymer were observed using SEM. According to a series of experimental results, the preparation and characterization of insoluble pyridinium‐type polymers are analyzed and discussed. This work can prepare the ground for a study on the antibacterial activity of insoluble pyridinium‐type polymers. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 668–675, 2000
