Manufacturing Technique and Bacteriostatic Property Evaluation of Polyvinyl lcohol/Sodium Alginate/Angelicae Dahuricae Radix Fibrous Membrane

摘要

This study aims to produce bacteriostatic fibrous membranes, and polyvinyl alcohol (PVA), sodium alginate (SA), and Angelicae Dahuricae Radix (AC) are used to form PVA/SA/AC fibrous membranes. This study uses different solvents for the extraction of AC extracts. Fiber types, ultraviolet absorption spectrum analysis, and bacteriostatic property test are performed on the resulting fibrous membranes to evaluate bacteriostatic effects of different solvent and extraction times; thereby determining the optimal AC extract. The experiment results show that AC that extracted with ethanol for 48 hours provides resulting membranes with significant bacteriostatic effect.
