Inorganic-organic hybrid composites have been intensively investigated to overcome organic’s own weaknesses such as poor electrical conductivity and thermal conductivity. Recent researches have suggested whole blended hybrid composites, which were prepared by homogeneously mixing inorganic particles in organic matrix in melt or solution states. In this study, for comparison, alumina nitride (AlN) was uniformly and selectively embedded in the surface region of polycarbonate (PC) by directional melt crystallization (DMC) technique. DMC was developed as a simple surface treatment method to manufacture homogeneously patterned porous morphology at polymer surfaces. Through this treatment, AlN was embedded in the pore walls and it shows these unique properties; i.e., different contact angle and higher thermal conductivity at in-plane direction, etc. This novel technique is expected to be easily applicable to other inorganic-organic hybrid materials. |
