Nanometer microcrystalline cellulose reinforcing polylactic acid glycolic acid electrospun membrane, preparation method thereof and application

Abstract

The invention discloses a nanometer microcrystalline cellulose reinforcing polylactic acid glycolic acid electrospun membrane, a preparation method thereof and application and relates to the field of biomedicine. Two natural organic polymer materials of PLGA and CNCs are composited, the method of preparing the electrospun film through electrospinning can effectively enhance the strength and the bioactivity of the materials, give full play to the biological nanometer effect and effectively compensate for the limitation of pure PLGA in biomedical application, and wound healing is well facilitated. In addition, the CNCs reinforcing PLGA electrospun membrane prepared through the method can also be used in fields of medicine controlled slow-release, repair of organs, such as skin, nerve and heart, tissue regeneration and the like.

Description

technical field

[0001] In the field of biomedicine, the invention specifically relates to a nano-microcrystalline cellulose-reinforced poly(lactic-co-glycolic acid) electrospun membrane, a preparation method thereof, and an application thereof. Background technique

[0002] Cellulose is the most abundant renewable resource in nature. It mainly exists in various plants and other agricultural by-products. It is a kind of cheap and sustainable polymer material. In today's world where the environment is deteriorating, it is of great significance to develop and use biodegradable cellulose resources. Historically, cellulose was the main research object during the birth and development of polymer chemistry. The results of cellulose research have made important contributions to the establishment and development of polymer science. In particular, the properties of cellulose that can be processed and modified into materials for different applications are well understood. Nowadays, c...
