Preparation and Investigation of Polyvinylpyrrolidone Blend Membranes: A Research-Based Comprehensive Experiment

Department of Chemistry, College of Science, Northeastern University, Shenyang 110819, P. R. China

Received Date: 17 October 2019

A research-based comprehensive experiment was introduced: preparation and investigation of polyvinylpyrrolidone (PVP) blend membranes in which PVP was employed as the membrane matrix. Three kinds of engineering thermoplastics were chosen to enhance the dimensional and mechanical stabilities of PVP based membranes. The physicochemical properties were investigated. This experiment relates to physical chemistry, polymer chemistry, organic chemistry, electrochemistry and instrumental analysis. It covers polymer blending, membrane fabrication by solution casting, characterization and performance test. Through this experiment, students can get knowledge of fabrication and characterization methods for polymer electrolyte membrane, which arouses students' interest in scientific research, cultivates students' innovative ability, fosters students' practical skills and promotes their integrative skills of applying knowledge.
