Manufacturing certain surface morphology has been challenging in the polymer industry. Patterned morphology assigned some functional properties; hydrophobicity or engineered friction, etc, to polymer surfaces. However, these strength couldn’t often overcome polymer’s weakness; low electrical conductivity, magnetic conductivity, etc. Herein, we made inorganic-nanoparticle-loaded polymer surfaces by directional melt crystallization (DMC) of solvents. DMC is a simple technique to make uniformly porous morphology on polymer surfaces. Silica nanoparticle and polycarbonate (PC) were chosen as an inorganic nanoparticle and a polymer substrate. 1,4-Dioxane was used as a solvent to disperse silica nanoparticles and dissolve PC surfaces. By decreasing temperature of PC surface right before treating, the resulting surface morphology showed a decrease in pore size. The effects of carried silica were optimized at contact angle and sliding angle. Through this technique, embedding other inorganic materials in polymer sheets can be simply done. |
