淀粉-聚乙烯醇生物降解薄膜的制备研究

摘要

本文以淀粉为和聚乙烯醇(PVA)原料，采用交联共混反应制备淀粉-PVA生物降解薄膜。考察了淀粉-PVA薄膜制备过程中诸因素对薄膜各项性能和生物降解性的影响。结果表明，淀粉-PVA薄膜各项性能优良，具有生物降解性。%Starch-poly(vinyl alcohol) (PVA) biodegradable membrane has been prepared by the crosslink-blending reaction. The relationship of preparation parameters and properties of the membrane has been investigated. The results indicate the prepared membrane possesses excellent properties and biodegradation.
