Abstract

ABSTRACT

Polymeric polypyrrole and polythiophene solid phase microextraction (SPME) coatings were prepared using electropolymerization with a linear sweep voltammetry technique. Physicochemical properties were measured using different methods, in particular small angle X-ray scattering and scanning electron microscopy. By using innovative approaches for pore size measurement, we were able to calculate a maximum of the pore size range from 80 to 90 nm. Additionally, film thicknesses measured from 90 to 150 μm. Using scanning electron microscopy, we describe the characteristics of polymer growth on the support surface.

摘要

采用线性扫描伏安法通过电聚合制备了聚合物聚吡咯和聚噻吩固相微萃取（SPME）涂层。使用不同方法测量了其物理化学性质，特别是小角X射线散射和扫描电子显微镜。通过采用创新的孔径测量方法，我们能够计算出最大孔径范围为80至90纳米。此外，测得的膜厚度为90至150微米。利用扫描电子显微镜，我们描述了聚合物在载体表面生长的特征。
