查询词典 high polymer

But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.

但是由于纳米粒子表面极强的活性，使它们很容易团聚在一起从而形成带有若干弱连接界面的尺寸较大的团聚体，这大大降低甚至消除了纳米颗粒的实际应用效果，同时由于纳米粒子表面亲水疏油，在有机高分子树脂中难于均匀分散，界面上会出现空隙，当空气中的水分进入空隙中就会触发界面处高聚物的降解、脆化，导致涂层失效。
