Abstract

The invention discloses a single-chain super intramolecular cyclization polymer, and a preparation method thereof. According to the preparation method, polyethyleneglycol diacrylate is taken as a monmer, zero valent copper adjusted controllable active free radical polymerization is adopted for polymerization of monmer polyethyleneglycol diacrylate, chain growth and intramolecular cyclization are promoted, intermolecular cross-linking is inhibited, and the single-chain super intramolecular cyclization polymer is obtained. According to the single-chain super intramolecular cyclization polymer, linear polyethyleneglycol diacrylate and annular polyethyleneglycol diacrylate are formed in polymer single chains. It is shown by polymer characterization that: the Mark-Houwink Equation constant is lower than 0.5, the structure of the single-chain super intramolecular cyclization polymer is similar to spherality, and a hydrogel material can be prepared via solidification of a polymer aqueous solution via ultraviolet light crosslinking.

Description

technical field [0001] The invention belongs to the field of novel biomedical materials, and mainly relates to a novel single-chain ultra-internal cyclic polymer and a preparation method thereof. Background technique [0002] Wound dressings are the primary modality in the treatment of acute and chronic wounds. In recent decades, various special wound dressings have been researched and invented according to different wound conditions. Among them, as one of the new wound dressings, hydrogel wound dressings have been widely used due to their smooth surface, good biocompatibility, tight integration with uneven wounds, and promotion of epithelial cell growth. However, the currently widely used synthetic hydrogel dressings generally have problems such as poor wound tissue adhesion, mismatch between mechanical properties and wound tissue, and high biological toxicity. Studies have found that the performance of synthetic hydrogel wound dressings can be improved by controlling the...
