Paper Title:
Sol-Gel Synthetic Model of Bi-Structured Bioactive Nano-Hybrids in TEOS-PDMS System
  Abstract

Ceramic-polymer bi-structured nano-hybrid, in which the bioactive silicate surface is nano-hybridized with flexible polymeric bulk, was synthesized in the tetraethoxysilane (TEOS)-polydimethylsiloxane (PDMS) sol-gel system. Different solutions for surface and bulk, whose compositions of TEOS: PDMS were respectively fixed 100: 0 and varied from 50: 50 to 20: 80 with various molecular weight (Mw) of PDMS, were subjected to lamination and controlled polymerization and condensation process, producing a large transparent crack-free monolithic bulk. Characterizations at near-surface cross-section of the bi-structured hybrids revealed that typical bioactive silicate was combined with all types of bulk hybrids regardless of their PDMS contents and Mw without distinct interface, indicating possibility of a novel bioactive nano-composite with enhanced physical and biological functions.
