摘要
以硅氧烷为疏水剂,通过液相、气相沉积方法在不锈钢表面成膜,构建稳定的疏水性表面。通过静态接触角及滚动角对其进行表征,对改性后的不锈钢进行相同条件的冰冻,比较其融冰时间,研究其防冻性。结果表明:十六烷基三甲氧基硅烷液相成膜的疏水性膜性能最好,接触角为118o,滚动角13o;十八烷基三甲氧基硅烷气相成膜的不锈钢片防冻能力最佳,融冰时间最短60s,不锈钢表面沉积疏水膜能够提高其防冻性能。
By depositing different thinning films of hydrophobic agent on the stainless steel surface through liquid and vapor deposition methods, a stable hydrophobic surface was formed. Their contact angles and sliding angles were meas- ure＆ The results showed that the highest static contact angle of them was film of hydrophobic agent 1 to 118o, sliding an- gles was 12o~ The best antifreezing film was agent 3, frozen time was 60s, Which indicated that surface modification of stainless steel can improve their antifreezing properties.
