摘要

聚乙烯醇（PVA）在水乙醇 PVA 溶液中通过裂解拉伸薄膜，直接加入到高密度聚乙烯（HDPE）的介孔结构中。差示扫描量热法和 X 射线分析探讨了 HDPE-PVA 纳米复合材料的结构和热物理性质。研究发现，由于空间限制阻止了 PVA 的结晶，因此 PVA 在 HDPE 主基体的介孔结构中以非晶化状态存在。

Amorphization of poly(vinyl alcohol) in the mesoporous matrix based on high-density polyethylene

Poly(vinyl alcohol) (PVA) was incorporated into the mesoporous structure of high-density polyethylene (HDPE) directly upon the tensile drawing of films via crazing in water–ethanol PVA solutions. The structure and thermophysical properties of the HDPE–PVA nanocomposites were explored by differential scanning calorimetry and X-ray analysis. PVA was found to exist in an amorphized state within the mesoporous structure of the HDPE host matrix since its crystallization is prevented by the spatial confinements.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
