The goal of this paper is to prepare surface-conductive glass fibers. The fibers were first hydroxylated, after which they were reacted with 3-bromopropyltrichlorosilane to form a bromopropylsilane monolayer, which was further reacted with aniline to substitute the bromine atoms. The surface-bound aniline molecules were used as active sites for the graft polymerization of polyaniline (PANI). The composition, structure and the morphology of the modified glass fiber surface were examined by X-ray photoelectron spectroscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy. The method generated a smooth and homogenous thin layer of PANI on the surface of the glass fiber with a surface conductivity of about 6 S/cm, hence larger than the usual value ( approximately 1 S/cm) of the bulk polyaniline.
本文的目标是制备表面导电玻璃纤维。首先将纤维进行羟基化处理,之后使其与3-溴丙基三氯硅烷反应形成溴丙基硅烷单分子层,该单分子层再与苯胺反应以取代溴原子。表面结合的苯胺分子用作聚苯胺(PANI)接枝聚合的活性位点。通过X射线光电子能谱、扫描电子显微镜和傅里叶变换红外光谱对改性玻璃纤维表面的组成、结构和形态进行了研究。该方法在玻璃纤维表面生成了一层光滑且均匀的聚苯胺薄层,其表面电导率约为6 S/cm,因此高于本体聚苯胺的通常值(约1 S/cm)。
