Novel silane compositions have been prepared by reacting a 3-isocyanatopropyl trialkoxysilane with an alcohol or diol having a divalent alkylene or alkylene-ether group. The alcohol or diol has a formula weight less than about 5000. The compositions can be used to modify the surfaces of inorganic oxygen-containing materials, including but not limited to silica, silicates, borosilicates, aluminosilicates, days, and metal oxides.
Surface treatment of silica nanoparticles with these compositions improves their improved dispersion in polyester nanocomposites.
新型的
硅烷组合物是通过将3-异
氰酸基丙基三烷氧基
硅烷与具有双价烷基或烷基-醚基的醇或二元醇反应制备而成。该醇或二元醇的分子量小于约5000。这些组合物可以用于改性无机氧含量材料的表面,包括但不限于
硅石、
硅酸盐、
硼硅酸盐、铝
硅酸盐、氧化物等。使用这些组合物对
二氧化硅纳米颗粒进行表面处理,可以改善它们在聚酯纳米复合材料中的分散性。
