23 Jul PFB water response shape memory tissue engineering scaffold and preparation method thereof
Abstract
The invention relates to a PFB water response shape memory tissue engineering scaffold and a preparation method thereof. The scaffold is a porous scaffold which is acquired in the manner of cross-linking hydroxylated high-molecular material PFB. The preparation method comprises the following steps: (1) preparing PFB and (2) preparing the PFB into a solution and then adopting a salt fractionation method for cross-linking, thereby acquiring the PFB water response shape memory tissue engineering scaffold. The PFB used in the invention has excellent hydrophilicity and heat stability; the porous PFB scaffold is prepared in the manner of thermal treatment processing and the mechanical property thereof can be regulated through the processing time; the scaffold has an obvious water response shape memory effect under a mild condition; besides, due to a large quantity of exposed hydroxide radicals, the PFB can be functionally modified; the PFB having high biocompatibility and potential application in the biomedical field is proved.
