23 Jul Polymethyl methacrylate stereo-structural composite superfine fiber material and preparation method thereof
Abstract
The invention provides a polymethyl methacrylate (PMMA) stereo-structural composite superfine fiber material and a preparation method thereof. The PMMA stereo-structural composite superfine fiber material featuring good biocompatibility and stronger heat-resistant quality, light and soft texture, and good breathability is prepared by dissolving isotaxy PMMA with mass percent being 25-40% and syndiotaxy PMMA with mass percent being 60-75% in N,N-dimethyl formamide (DMF) having strong matingreaction, heating to prepared a mixed solution, and injecting the mixed solution in an electrostatic spinning device for electrostatic spinning. The PMMA stereo-structural composite superfine fiber material can be widely used as tooth fillers, tissue engineering bracket material, etc.
