Title:
POLYMERIZATION METHOD MEDIATED AND INITIATED BY OXYGEN-RESISTANT AND BIOCOMPATIBLE METALLIC TIN AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/241033
Kind Code:
A1
Abstract:
Disclosed in the present application are a polymerization method mediated and initiated by oxygen-resistant and biocompatible metallic tin and the use thereof. The polymerization method comprises: subjecting a pre-reaction mixed solution comprising a free radical polymerization monomer, a coordination agent and a solvent to a polymerization reaction confined between metallic tin and a substrate deposited with an initiator, thereby preparing a biocompatible polymer brush thin film. The polymerization method provided in the present application uses a metallic tin sheet/foil to mediate a surface initiated polymerization reaction, is simple, convenient and efficient, has high polymerization efficiency, requires no addition of any metal salt, requires no complex deoxygenization operation or inert environment, and can achieve large-scale preparation. Moreover, the method avoids the use of a copper catalyst, overcomes the defects of a high price, high toxicity, etc., caused by the use of metal copper and a copper salt as catalysts in existing atom transfer radical polymerization systems, and has huge application potential in the field of biomedicine.
