    • The invention provides a compound and method of producing the same. The method of the invention includes the following steps. First of all, Polycaprolactone (PCL), dimethylol propionic acid (DMPA), 4,4′-methylenebis (cyclohexyl isocyanate) (H12MDI), and dibutyltin dilaurate (DBT) are mixed in a solvent in the first place and a solution is formed. This solution is then mixed with triethylamine (TEA) and triethylene tetramine (TETA). After that, amino-terminated anionic waterborne polyurethane (WPU) is produced. A sol-gel process is proceeded with a mixture of amino-terminated anionic waterborne polyurethane, tetraethylorthosilicate (TEOS) without any extra catalyst, and a compound, waterborne polyurethane-silica nanocomposite materials, is eventually produced.
    • 本发明提供了一种化合物及其制备方法。 本发明的方法包括以下步骤。 首先将聚己内酯(PCL),二羟甲基丙酸(DMPA),4,4'-亚甲基双(环己基异氰酸酯)(H12MDI)和二月桂酸二丁基锡(DBT)首先在溶剂中混合,形成溶液 。 然后将该溶液与三乙胺(TEA)和三亚乙基四胺(TETA)混合。 之后,生成氨基封端的阴离子水性聚氨酯(WPU)。 溶胶 - 凝胶法用氨基封端的阴离子水性聚氨酯,原硅酸四乙酯(TEOS)与无任何额外催化剂的混合物进行,最终生产化合物水性聚氨酯 - 二氧化硅纳米复合材料。
