Preparation,Microstmcture and Morphology of Electrospun Sulfonated Polystyrene Films for Proton Exchange Membrane Hydrogen Fuel Cell

摘要

Sulfonated electrospun polystyrene SPS fibers were prepared by electrospininig technique.Solution of 30 wt.% PS in DMF(N,N-dimethylformamide)were prepared,(PS)electrospun films were fabricated by electrospinning technique.Sulfonation reaction were introduced by immersion the PS electrospun films in diluted sulfuric acid(H2SO4)of concentration 1 M for(1,2,3,4)hr.FTIR spectra was used to detect the sulfonation peaks which is found in the sulfonated elecrospun films and absent in the unsulfonated films.This indicates successful sulfonation process for the films.SEM coupled with EDS tests were used for revealing the structure and observe the surface of the elctrospun films before and after sulfonation reaction.
