Engineering surface chemistry and morphology has been a major area of the materials science and engineering. Surface porous structures can dramatically change the surface properties such as contact angle. However, the combination of two different materials only at the surface region by post surface treatments has seldom been investigated. Herein, we suggest a fabrication of inorganic materials/polymer composite surfaces with introduction of surface pores by directional melt crystallization (DMC) as a post surface treatment. DMC can successfully produced patterned porous morphology of inorganic particles and polymers. Silica nanoparticles were used as the inorganic material and polycarbonate (PC) as a polymer substrate. Silica nanoparticles were well dispersed in 1,4-dioxane, and the nanoparticles could be uniformly combined with the PC molecules on the surfaces. The resulting surfaces of PC showed rather uniform pores and silica nanoparticle embedded pore walls. |
