目的 聚甲基丙烯酸甲酯（PMMA）是一种具有良好透光性、耐候性、电绝缘性和加工性能的高分子材料，但也存在脆性大、耐热性差、易黄变和表面易划伤等缺陷，因此通过形成具有互穿网络结构的PMMA来改善其缺陷，从而拓宽PMMA的应用领域。方法 通过文献进行分析，详细阐述顺序型、同步型、Semi型、胶乳型、热塑型和纳米复合型的合成方式，并对具有互穿网络结构PMMA共混体系在导电、功能膜、阻尼、生物医学、涂料等领域的应用进行整理和综述。结论 分析了目前互穿网络结构PMMA共混体系相关研究的不足，并提出PMMA在包装领域代替传统透明材料以及在高层建筑中代替钢化玻璃的应用展望。

Polymethyl methacrylate (PMMA) is a polymer material with good light transmission, weather resistance, electrical insulation and processing properties, but it also has the defects such as high brittleness, poor heat resistance, yellowing and surface scratch. The work aims to improve the defects by forming PMMA with interpenetrating network structure, thus widening the application field of PMMA. The literature analysis was carried out to clarify the synthesis methods of sequential, synchronous, semi, latex, thermoplastics and nanocomposites in detail. Applications of PMMA blending system with interpenetrating network structure in the fields of conductivity, functional film, damping, biomedicine and coating were reviewed. The shortcomings of the current research on IPN PMMA blending system are analyzed, and the application prospect of IPN PMMA blending system replacing traditional transparent materials in the field of packaging and toughened glass in high-rise buildings is put forward.
