23 Jul CS/PVA compound nanofibre containing multi-walled carbon nanotubes (MWNT) and preparation method thereof
Abstract
The invention relates to a CS/PVA compound nanofibre containing multi-walled carbon nanotubes (MWNT) and a preparation method thereof. The CS/PVA compound nanofibre comprises the following components of chitosan CS/ poval PVA and MWCNT, wherein the mass ratio of the chitosan CS to the poval PVA is 1:2-1:4, and MWCNTs account for 1 wt% of the total mass of solute. The preparation method comprises the following steps: (1) respectively preparing CS and PVA solutions, adding MWCNTs, and preparing the nanofibre by an electrostatic spinning technology; (2) carrying out glutaraldehyde crosslinking processing on the prepared nanofibre to obtain water-insoluble nanofibre; and (3) drying crosslinked fibre in vacuum to obtain the required compound nanofibre. The prepared nanofibre has strong mechanical behaviour, high porosity, good biocompatibility, simple preparation process, easy operation and wide application in the aspect of tissue engineering.
