23 Jul Method for preparing degradable polymer nano-fiber through chemical vapor deposition technology
Abstract
The invention discloses a method for preparing a degradable polymer nano-fiber through a chemical vapor deposition technology, and belongs to the technical field of materials. The main chain-degradable copolymer nano-fiber is successfully prepared according to a free radical polymerization mechanism with nematic liquid crystals as a template by introducing unsaturated annular acetal-5,6-benzo-2-methylene-1,3-dioxepane (BMDO) into poly-p-xylene or bisfunctionalized poly-p-xylene by adopting a chemical vapor deposition (CVD) technology. The preparation method realizes the controllable size, morphology and composition of the fiber, solves the solvent post-treatment problem of a fiber produced through a traditional electrostatic spinning method, and avoids the severe environment pollution andother disadvantages, and the fiber obtained in the invention can be applied to drug release systems, tissue engineering, micro-fluid devices, and has very high application values.
