尼龙12/聚乙烯醇阻隔材料性能研究
Chinese Journal of Colloid & Polymer（2017）
Abstract
按照不同质量比将尼龙12和不同分子量PVA共混得到PA 12/PVA阻氧薄膜.当PA 12/PVA阻氧薄膜中PVABP05,PVABP08,PVABF14含量分别达到37.5,33.3和23.1wt％时,其氧气阻隔速率和自由体积(Vf)分别达到一个最小值;随着PVA聚合度降低,PA 12/PVA薄膜的氧气渗透速率和Vf值进一步降低,最佳阻氧性能PA 12625PVABF05样品的氧气渗透速率和Vf数值分别为77 cm3/m2.day.atm和1.82×10-3 nm3.
