AI Technical Summary
The non-degradability of synthetic fibers leads to environmental pollution and generates harmful microplastics during use. There is a lack of high-strength biodegradable fiber materials.
A high-strength biodegradable fiber was prepared by using a three-step synthesis method, which involves the preparation of a polyester main chain segment and a modified chain segment containing a polyester with a specific structure, including the cyclization prepolymerization of dicarboxylic acid and amino diol, the acquisition of hydroxyl-terminated polyester prepolymer and polycondensation reaction.
It has achieved the preparation of high-strength biodegradable fibers that combine full degradability and good mechanical properties, thereby reducing environmental pollution.
