제목 Improved tensile strength of bacterial cellulose/poly(vinyl alcohol) double network structures
초록 The practical application of bacterial cellulose (BC) produced by Gluconacetobactor xylinus is limited due to its poor mechanical properties especially in tensile strength. In order to increase the applicability of BC, poly(vinly alcohol) (PVA) is introduced for the formation of double networked structure through the diffusion of PVA molecules into the BC networks. The BC/PVA double networked cryogel shows the increase in tensile strength over 6 folds of pure BC hydrogel due to the efficient dissipation of energy. The preparation method and the characterizations for verification of the network structure and the improvement of mechanical properties will be demonstrated in the presentation.
