A moderate hydrophilicity and exudate uptake capacity can often favour cell adhesion and wound healing potential, however, most of the synthetic polymers like polycaprolactone (PCL) are hydrophobic. Hydrogels based on natural polymers can improve the hydrophilicity and exudate uptake capacity of synthetic dressings and improve healing. In this work, we report the development of chitosan ascorbate-infiltrated electrospun PCL membranes. Our study demonstrated that chitosan ascorbate infiltration improves the hydrophilicity as well as water uptake capacity of the membranes and highly favoured the adhesion of human umbilical vein endothelial cells and human mesenchymal stem cells on the membranes.Graphical abstract
