针对乙烯-醋酸乙烯酯共聚物（EVA）的改性处理及其与纳米材料的复合体系研究进展进行了系统梳理。指出石油行业纳米基材的研发方向调整为有机改性体系、有机/有机-无机杂化体系以及有机纳米微球体系，并且新型材料与EVA类降凝剂复合成都稳定性及降凝效果显著增强，为优化原油低温流变性提供了新思路。
Abstract：This article systematically reviews the research progress on the modification of ethylene-vinyl acetate copolymer(EVA) and its composite system with nanomaterials. Currently, the development direction of nanomaterials in the petroleum industry has shifted towards organic modified systems, organic/organic-inorganic hybrid systems, and organic nanosphere systems. The composite system of novel materials with EVA-based pour point depressants significantly improves stability and pour point depression performance, providing new insights for optimizing the low-temperature flow properties of crude oil.
