23 Jul Photosensitive degradable comb-like copolymer film with controllable surface appearance and performance
Abstract
The invention relates to a photosensitive degradable comb-like copolymer film with controllable surface appearance and performance and belongs to the field of functional polymer materials. Firstly a reaction is carried out on cinnamoyl chloride (CC) and epsilon-caprolactone modified methacrylate (FMn, n is equal to 1-3), so that a series of photosensitive macromolecule monomers (FMnC) are obtained; the FMnC and polyethylene glycol methacrylate (MAPEG) are taken as a first monomer and a second monomer, then free radial copolymerization is carried out on the first monomer, the second monomer and a third monomer such as styrene (St), glycidyl methacrylate (GMA) and tert-butyl methacrylate (BMA), so that a photosensitive degradable terpolymer with a comb-like structure is prepared; a solvent volatilization method is adopted to prepare the product photosensitive degradable terpolymer with the comb-like structure into the film, and study shows that the photosensitive degradable comb-like copolymer film has photosensitivity and degradability; surface appearance and wettability of the photosensitive degradable comb-like copolymer film can be controlled by changing polarity and addition amount of a selective solvent. The obtained photosensitive degradable copolymer film with controllable surface appearance and performance is expected to be taken as an intelligent degradable material and widely applied to the fields of tissue engineering materials, medical materials and the like.
