摘要
利用模板技术制备了聚二甲基硅氧烷光盘沟槽微结构薄膜,采用电子显微镜对材料进行表征并对薄膜的润湿性各向异性进行了研究.结果表明:刻录可以使光盘沟槽加深,利用聚二甲基硅氧烷复制的薄膜表面具有与光盘基本一致的表面微结构,但沟槽深度比原光盘有所降低.平行沟槽方向的接触角大于与垂直沟槽方向的接触角,具有明显的润湿各向异性.
The groove micro-structure of compact disc was copied by utilizing the template technology,and polydimethylsiloxane film was prepared.Besides,we adopted SEM to measure the materials and contact angle meter for bearings to research wetting of the duplicate film.The results indicated that groove depth of the burnt compact disc was deeper than compact disc.The groove depth of polydimethylsiloxane film was lower than the compact disc.The contact angle of the groove micro-structure film of polydimethylsiloxane in the parallel direction of grooves was greater than that in perpendicular direction.And the wetting anisotropy was remarkable.
