摘要
在微生物驯化环境中,聚乙烯醇具有生物降解的潜力。该文综述了PVA生物降解的机理、影响因素、降解性的评价方法,以及降解环境对PVA降解性的影响,并对近年来基于PVA的共聚/共混材料的制备及其生物降解性能的研究进行了较为详细的概述.
Poly （vinyl alcohol） （PVA） and its derivatives, the excellent water-soluble polymers, have attracted more and more attention, as they show the usability in many processes, as well as possess the promise of degradation in the presence of some specific microbials. In the present paper, the recent advances in the biodegradation of PVA and its derivatives, including the mechanism, influential factors, evaluation method and degradation environment etc, have been reviewed. Moreover, the latest development of PVA-based blends/composites and their biodegradation is also introduced in the present article.
