摘要

Bacterial cellulose (BC) has established to be a remarkably versatile biomaterial and can be used in wide variety of applied scientific endeavours, especially for medical devices, lately, bacterial cellulose mats are used in the treatment of skin conditions such as burns and ulcers, because of the morphology of fibrous biopolymers serving as a support for cell proliferation, its pores allow gas exchange between the organism and the environment. Moreover, the nanostructure and morphological similarities with collagen make BC attractive for cell immobilization and cell support. In this work, we obtain first electrospun bacterial cellulose mats after chemical treatment and without conductive additives. With DMA/LiClmechanism dissolution, modified bacterial cellulose was easily electrospun in chloroform/acetone solvents in comparison with BC unmodified. FTIR peaks results are consistent with proposed interactions between cellulose and DMA/LiCl solvent system.
