Abstract:
Cross-linked siloxane/silsesquioxane-based elastomers were easily prepared in 15 min via the anionic ring-opening polymerization of cyclotetrasiloxane (D4) and a polyhedral oligomeric silsesquioxane, using K2CO3 as a catalytic base in dimethylformamide at 70 °C. The resulting silicone elastomers have high mechanical strength, good thermal stability, and good superhydrophobic properties.
