Synthesis and characteristics of networked polycarbosilanes having urethane-crosslinked glucose groups

Networked polycarbosilanes having glucose groups were synthesized and their physicochemical properties were investigated. Film-shaped polysilacyclobutane having glucose pendant groups was crosslinked by thermal urethane formation with a crosslinker, hexamethylene diisocyanate (HMDI). Several films w...

Description
Summary:Networked polycarbosilanes having glucose groups were synthesized and their physicochemical properties were investigated. Film-shaped polysilacyclobutane having glucose pendant groups was crosslinked by thermal urethane formation with a crosslinker, hexamethylene diisocyanate (HMDI). Several films were prepared by varying the feed ratio of [Glucose]/[HMDI]. Thermal stability, phase transitions, mechanical strength, and water absorption were examined by thermal gravimetric analysis, differential scanning calorimetry, tensile tests, and immersion swelling in water. We found that the networked polycarbosilanes having glucose groups were thermally stable, flexible, and tough materials with moderate hydrophilicity, which depends on the urethane crosslinking density. Graphical abstract Networked polycarbosilanes having glucose groups were synthesized and their physical properties were investigated. Film-shaped polysilacyclobutane having glucose pendant groups was crosslinked through urethane formation by heating with a cross-linker, hexamethylene diisocyanate. We found that they were thermally stable, flexible, and tough materials with moderate hydrophilicity.
