一、产品说明

     PDMS有机硅薄膜属于一种高分子弹性聚合物薄膜,以聚二甲基硅氧烷为原料经特殊工艺制备。由于聚二甲基硅氧烷材料的特性,赋予了PDMS薄膜一定特异性能。永久弹性、低杨氏模量、优异的气体透过性、化学稳定性、热稳定性、低温柔韧性(-60~200℃保持优异性能)、全透明性、生物相容性。由于PDMS薄膜具备以上很多有机/无机薄膜无法同时具备的特殊性能,使得该产品在最近几年成为人们重点的研究对象。

三、应用实例

      生物芯片、微流控芯片、薄膜传感器柔性衬底、薄膜电容器介电材料、电活性聚合物材料、可穿戴智能电子产品、复合功能膜制备等

 

四、产品特性

1、有机硅薄膜生物相容性较好,对人体无害,属安全环保产品;

2、有机硅薄膜较为柔软,贴附性较好,触感舒适;

3、薄膜具备永久弹性,在拉伸一定长度后(只要不拉断),薄膜均会恢复原来形状,不会有明显形变变化;

4、伸长率较好,300~1000%范围内

5、产品介电绝缘性较好,是制备智能柔性电子产品的柔性衬底的最佳选择;

6、薄膜具备高透气型,类似人体皮肤,是制备机器人、透气型创可贴(疤痕贴)、气体分离的最佳选择。
