Enhancement of electro-conductivity of polyethylene/polyacetylene mixture by interfacial electro-polymerization

超高分子重量聚乙烯（UHMWPE）是从凝胶状态中的溶液中结晶化的。聚乙酸酯（PA）在凝胶中聚合。这些预先准备好的UHMWPE和PA的混合物是以压制成模具的表格的形式处理的。所述electro-conductivity of the as-prepared sheet reached 10 -1-D1S/cm by doping Iodine。The electro-conducity of drawn sheet in the direction parallel to the drawn direction（创作） is 10-D1 S/cm and that in the transverse direction（创作D2） 10-D1 S/cm。Ratio of？/？D2？D2？D2？D14？D1.也就是说，电作用是预期通过绘制增加分子方向的，绘制的电影的价值比未绘制的电影小，而且与绘制的相反，绘制的分子方向的价值比绘制的电影小，绘制的电影的价值比绘制的电影的价值要小，并达到对比，它用更进一步的绘制来减少。有两个理由认为：1）PA在绘制过程中被氧化化，自从它在空中绘制以来，2）UHMWPE矩阵中的连接性被绘制中断。The same experiment was done by preparing the mixture of isotactic polypropylene（iPP） and PA。D2 of the drawn iPP/PA sheet were 10 -5-D1 S/cm and 10-D1 S/cm， respectively。The ratio of？还有，这些薄膜的电导电性的绝对价值并不总是很高，他们的抽取样本的高异构性是目前工作的显著结果，因为到目前为止没有这样的材料。我们的最终对象是准备一个薄的，电导电的薄膜，通过在UHMWPE/PA混合物中的电聚合化将其他电导电聚合物作为电导电聚合物，通过使用它作为一种电子。“目前混合物的电条件对于目的来说还不够高。”它将试图改善混合物的电行为。

Ultra-high molecular weight polyethylene (UHMWPE) was crystallized from the solution in decaline in the state of gel. Polyacetylene (PA) was polymerized in the gel. The thus prepared mixture of UHMWPE and PA was processed in the form of sheet by pressing into a mold. The electro-conductivity of the as-prepared sheet reached 10ィイD1-1ィエD1 S/cm by doping Iodine. The electro-conductivity of drawn sheet in the direction parallel to the drawn direction(αμ) is 10ィイD1-6ィエD1 S/cm and that in the transverse direction(σィイD2γィエD2) 10ィイD1-10ィエD1 S/cm. The ratio of μ/σィイD2γィエD2 is 10ィイD14ィエD1. Although the electro-conductivity is expected to enhance by increase of molecular orientation by drawing, the value of drawn film is smaller than that of undrawn film, and to the contrary, it molecular orientation by drawing, the value of drawn film is smaller than that of undrawn film, and to the contrary, it decreases with further drawing. Two reasons are considered : 1)The PA is oxidized in the process of drawing since it was drawn in the air and 2)the connectivity of PA in the UHMWPE matrix is broken by drawing. The same experiment was done by preparing the mixture of isotactic polypropylene(iPP) and PA. Theαμand αィイD2γィエD2 of the drawn iPP/PA sheet were 10ィイD1-5ィエD1 S/cm and 10ィイD1-10ィエD1 S/cm, respectively. The ratio of σμ/σィイD2γィエD2 is as high as 10ィイD15ィエD1. Although the absolute values of electro-conductivity of these sheets were not always high, their high anisotropy of the drawn samples is significant result of the present work, because so far there are no such materials as this.Our final object is to prepare a thin, electro-conductive film by electro-polymerization of other electro-conductive polymer on the UHMWPE/PA mixture, by using it as an electrode. The electro-conductivity of the present mixture is not high enough for the purpose. It will be tried to improve the electro-conductivity of the mixture.
