Abstract Novel photocatalytically active polydiphenylacetylene-ZnO nanocomposites in pristine and polystyrene matrix form were obtained by mixing a polydiphenylacetylene solution in different solvents (acetonitrile or toluene) with hydrothermally synthesized nanosized ZnO. The degradation of malachite green dye as a model pollutant in water solution under UV illumination was investigated using synthesized nanocomposite powders. The polydiphenylacetylene-ZnO-polystyrene nanocomposite in a powder form demonstrates higher photocatalytic ability about the degradation of MG (88%) than that of pristine polydiphenylacetylene-ZnO (64%) which could be explained by possible π-π interaction synergistic effect between the polymer partners.

基于聚二苯乙炔-氧化锌在聚苯乙烯基体中的新型染料降解光催化剂纳米复合粉末

摘要 通过将聚二苯基乙炔在不同溶剂（乙腈或甲苯）中的溶液与水热合成的纳米 ZnO 混合，获得了具有原始和聚苯乙烯基体形式的新型光催化活性聚二苯基乙炔-ZnO 纳米复合材料。使用合成的纳米复合粉末研究了在紫外线照射下作为模型污染物在水溶液中的孔雀石绿染料的降解。粉末形式的聚二苯乙炔-ZnO-聚苯乙烯纳米复合材料对MG（88％）的降解表现出比原始聚二苯乙炔-ZnO（64％）更高的光催化能力，这可以通过聚合物之间可能的π-π相互作用协同效应来解释伙伴。
