摘要

Reactive octa-aminopropyl polyhedral oligomeric silsesquioxane (POSS-NH_2) has a nano-sized structure with a cubic silica core and octa-aminopropyl groups distributed at eight corners. Carboxymethyl cellulose (CMC) is often used as a hydrogel polymer because of its water-solubility, renewability, biodegradability and biocompatibility. Novel POSS/CMC hybrid hydrogel was fabricatied here by the aggregation of POSS-NH_2 nanoparticles and the formation of POSS-CMC hybrid block copolymers, which was driven by the hydrogen bonding interactions between the amino groups of POSS-NH_2 and the carboxyl groups of CMC. d-( + )-gluconic acid 5-lactone (DGL) was used to alter the pH of the system which can further control the formation of hydrogen-bonding interactions. Our method provides a facile and effective route to fabricate novel hybrid hydrogel based on CMC or other cellulose derivatives.
