【摘要】 <正>决定无机填料填充热塑性复合材料物理力学性能的一个主要因素是无机填料与基体的相容性和界面结合状况。为改善无机填料与基体之间的相容性和界面结合状况,需要对无机填料进行表面处理。熊若华采用阴离子聚合反应制备了一种嵌段共聚物偶联剂,该偶联剂对云母进行表面处理,可显著地提高云母填充聚合物材料的力学性能,研究了嵌段共聚物的改性更多还原

【Abstract】 A tri-block copolymer coupling agent (PS-b-PBA-b-PMPS) was synthesized by atom transfer radical polymerization (ATRP), and its molecular structure was characterized by FT-IR and 1H NMR. The glass bead was treated with the block copolymer coupling agent, and then studied by TEM. The result shows that strong interaction was formed between the block copolymer coupling agent and the surface of glass bead, and the block of PBA formed a layer of film on the surface.更多还原
