Steric hindrance layer can be established when the surfaces of nano-Al_2O_3 were grafted with polyacetal, which ( increased) the dispersibility of the nano-particles as well as the compatibility between the particles and the resin matrix. 在纳米Al2O3表面接枝聚缩醛可在粒子表面建立起空间位阻稳定层,不但提高了纳米粒子的分散稳定性,还可以增强纳米粒子与树脂基体的相容性。
Through inorganic coating and organic modification of titanium dioxide respectively, we can improve powder reunion by using organic functional groups steric of titanium dioxide surface. At the same time, the coating of titania with organic functional groups improves the compatibility between the particles and nylon matrix. 通过对钛***的无机包覆和有机改性,可利用钛***表面较多有机官能团的空间位阻效应改善粉体的团聚情况,同时有机官能团改善了它与锦纶界面的相容性。
