23 Jul Mesoporous silicon oxide particle/degradable polymer nano composite fiber, preparation method and application thereof
Abstract
The invention discloses a mesoporous silicon oxide particle/degradable polymer nano composite fiber, a preparation method and application thereof. The method comprises the following steps of: uniformly dispersing mesoporous silicon oxide particles into a solution of degradable polymers; and then preparing nano composite fibers by adopting an electrostatic spinning process, wherein the mesoporous silicon oxide particles are uniformly distributed in the degradable polymer fibers. Compared with traditional polymer fibers, the nano composite fiber can be used for better controlling the release ofdrugs and has quicker biodegradability and higher mechanical strength, and meanwhile, the fiber has better cellular compatibility. The nano composite fiber can be used as a tissue engineering support, a drug release vector, a wound coating material or a functional membrane.
