Wuhan Textile University Yanbo Liu: Characterizationon Modification and Biocompatibility of PCL Scaffold Prepared with Near-field Direct-writing Melt Electrospinning 2021-06-26

Polycaprolactone(PCL) due to its good biocompatibility and biodegradability, is widely used in fracture fixation materials, surgical sutures, medical dressings, controlled drug release materials and tissue engineering scaffold materials. The research group of Professor Liu Yanbo from the School of Textile Science and Engineering of Wuhan Textile University explored the best process parameters for preparing PCL scaffoldsusing near-field direct-writingmelt electrospinning technology through orthogonal experiments. Based on the optimized process parameters, PCL scaffolds with different thicknesses, gaps and structures were prepared, and the corresponding hydrophilicity was characterized. The PCL scaffold is modified with chitosan (CS) and hyaluronic acid (HA) to improve biocompatibility and hydrophilicity. Fourier transform infrared spectroscopy (FTIR) analysis and antibacterial experiment results show that the adhesion of chitosan and hyaluronic acid on the surface of the PCL scaffoldhas

Humidity-induced electrospinning fibrous sponges used in high-performance warmth retention materials 2021-06-23

The current development direction of warmth retention materials is lightweight and efficient. Traditional fiber warmth retention materials have large diameters, resulting in heavy material weight and limited improvement in warmth retention. Common advanced warmth retention materials (such as metal reflectors and electric heating) have defects such as high cost and insufficient safety. Therefore, the development of lightweight and efficient warmth retention materials are still a major problem at present. In this paper, an ultra light and super elastic electrospinning fibrous sponge with low thermal conductivity and high thermal storage was prepared by humidity-induced electrospinning.

Electrospun Silk Material Systems for Wound Healing 2021-03-22

The functional properties of six distinct electrospun silk material groups were evaluated to assess conformational and biocompatible characteristics related to wound dressings. In a hydrated state, all six silk matrices exhibited absorption, water vapor transmission, oxygen permeation and enzymatic biodegradation suitable for full‐thickness wound sites. Employing constrained drying techniques, silk concentration was a determinate factor influencing material structural properties related to the storage and distribution of such wound dressing systems. Subsequently, three electrospun silk models demonstrated ideal biomaterial properties with potential utility for wound dressings.
