本文提出了一种制备PMMA/ZnO纳米复合材料的简便、通用方法，该材料具有高透明度、无颜色、热稳定性好、紫外吸收性好、力学性能提高等特点。所采用的工艺是将分散在DMAc中的ZnO纳米颗粒与溶解在相同溶剂中的PMMA基质混合。研究了ZnO含量对PMMA基体物理性能的影响。加入0.5% wt.-%的ZnO粒子后，合金的力学性能得到了显著改善。所描述的方法的优点在于，尽管是一种简单易行的方法，但它提供了纳米级（2-5纳米）的ZnO纳米颗粒混合到聚合物基质中。
A simple, facile and versatile approach is presented for the preparation of PMMA/ZnO nanocomposite materials, which possess high transparency, no color, good thermal stability, UV absorption and improved mechanical properties. The employed process involved mixing of ZnO nanoparticles dispersed in DMAc with the PMMA matrix dissolved in the same solvent. The effect of ZnO content on the physical properties of the PMMA matrix is studied. A significant improvement in mechanical properties was observed with the incorporation of 0.5 wt.-% ZnO particles. The beauty of the described approach lies in the fact that despite being a simple and facile approach, it offers nano-level (2-5 nm) mixing of ZnO nanoparticles into a polymer matrix.
