纳米粒子改性丙烯酸酯制备复合材料

作为分散相的纳米粒子以独立的相态形式通过改性,分散到作为连续相的丙烯酸酯聚合物基体中形成一种既保留无机材料的热稳定性与硬度,又兼具聚合物韧性与介电性能的复合材料,该过程不是无机相与有机相的简单混合,而是在纳米尺度内两相的有机复合。综述了近年来纳米粒子改性丙烯酸酯复合材料,重点介绍了纳米粒子种类、纳米粒子表面改性、复合材料制备方法及其工业应用等方面的研究成果,并对其发展方向进行了分析和展望。

Preparation of composites by nanoparticles modified acrylate

Inorganic/organic composites are composites formed by dispersing inorganic nanoparticles into polymer matrix. Nanocomposites are not simple mixtures of inorganic and organic phases, but two phases compounded in nanoscale. The nano-filler is used as the dispersing phase and the polymer matrix is used as the continuous phase. The dispersing phase is dispersed in the polymer matrix in an independent phase. Composite materials synthesize the thermal stability, hardness, toughness and dielectric properties of inorganic materials. By adjusting the homogeneity and degree of compounding of the composites, the optimum properties of the composites can be obtained. The addition of nanoparticles can greatly improve the mechanical properties of the materials, and has excellent catalytic performance. In this paper, the research achievements of nanocomposites in preparation methods, surface modification of nanoparticles, nano-modified particles and industrial applications in recent years are reviewed, and the development direction of nanocomposites is analyzed and prospected.
