Comparison of preparation and characterization of water-bath collected porous poly L –lactide microfibers and cellulose/silk fibroin based poly L-lactide nanofibers for biomedical applications

The hydrophobic nature of Poly L–Lactide (PLLA) limits its application in tissue engineering and drug delivery. In the present study, three methods were used to modify the hydrophobic properties of PLLA. In one method, hydrophilic PLLA fibers with open porous structure were produced by electrospinning method using water bath collector. In the second method, PLLA was made hydrophilic by the addition of hydrophilic polymers such as cellulose...
