Abstract

In this work, various methods to enable tailoring of polydimethylsiloxane film surfaces are implemented and compared to determine their influence on surface energy and roughness. Films were prepared containing various levels of hydrophilic silica filler. Ultraviolet-ozone, and Piranha solution treatments were also implemented and characterised. Lastly, the combination of both silica filler and treatments were utilised and characterised to understand interactive effects. Influence of filler loading, and surface treatment on roughness, and surface energy of films was determined. Regardless of surface treatment, addition of silica significantly influences total surface energy. Addition of silica influenced total surface energy of the films by itself, and in combination with the Piranha and UV-ozone treatments. The lowest surface energy was that of the control Polydimethylsiloxane film 21.5 N/m. The overall highest surface energy achieved was that of the 10% filled 30-minute Piranha solution treated sample, having a surface energy of 44.1 N/m.

表面处理二氧化硅填充和非填充聚二甲基硅氧烷薄膜的表征

在这项工作中，实现了各种方法来剪裁聚二甲基硅氧烷薄膜表面，并进行了比较，以确定它们对表面能和粗糙度的影响。制备了含有不同亲水性二氧化硅填料的薄膜。紫外臭氧和水虎鱼溶液处理也进行了实施和表征。最后，利用和表征了二氧化硅填料和处理的组合来了解相互作用的效果。测定了填料用量和表面处理对薄膜粗糙度和表面能的影响。无论表面处理方式如何，二氧化硅的加入都会显著影响总表面能。二氧化硅的加入对膜的总表面能有影响，同时与水虎鱼和uv -臭氧联合处理对膜的表面能也有影响。聚二甲基硅氧烷膜的表面能最低，为21.5 N/m。总体表面能最高的是10%的水虎鱼溶液处理过的样品，其表面能为44.1 N/m。
