Abstract
Disclosed herein is an initiator integrated polydimethylsiloxane (iPDMS). The iPDMS is a polydimethylsiloxane undergoing a hydrosilylation reaction. The initiator 10-undecenyl 2-bromo-2-methyl propionate is integrated on the surface of iPDMS by covalent bond. At % is 0.01-1% confirmed by X-ray photoelectron spectroscopy. Disclosed herein is a method for making an initiator integrated polydimethylsiloxane. Prepolymer A, cross-linker B and vinyl-terminated initiator C were mixed below a ratio of 10:1:4-0.01 for 6-24 hours, then the elastomer was formed. And, disclosed herein is functional surface modification of initiator integrated polydimethylsiloxane and its applications for biocompatibility, organic solvent compatibility and heat-sensitive materials.
Claims1
A polydimethylsiloxane carrying an initiator on its surface, which results from a hydrosilylation reaction, with 10-undecenyl 2-bromo-2-methyl propionate in 0.01-1 At % being fixed on its surface through covalent bond.
