一般說明

聚二甲基硅氧烷(PDMS)是一种硅基有机聚合物,是一种无毒、光学透明、惰性、不可燃的材料。它被广泛用于耐热润滑剂、阻燃剂、医学设备和化妆品。聚二甲基硅氧烷具有疏水性、细胞相容性、黏弹性,可用于纺织工业中防水涂层的制备。

應用

PDMS可作为前体用于 合成具有改善的机械和热性质的聚二甲基硅氧烷-聚氨酯弹性体。

由于其高机械强度、 透明度和氧渗透性, PDMS是眼科应用的首选材料。 它可作为预聚物用于制备 葡萄糖可渗透的PDMS和(N-n-异丙基丙烯酰胺 的互穿网络(PNIPAAM)。这种网络可用于眼科应用。

PDMS也可用于合成 耐火、耐热的聚氨酯-PDMS杂合体。PDMS的加入 为聚氨酯带来了热解条件下的低可燃性和热稳定性。

PDMS可作为添加剂用于制备 TEOS基石头保护杂合体 无裂纹干凝胶PDMS的加入加速了胶凝过程并 有助实现有效的石头保护。
