摘要: Abstract In an attempt to improve the biological behavior of pristine bacterial cellulose (BC), lecithin (LEC) has been immobilized on surface BC nanofibers by solution immersion and subsequent chemical crosslinking with proanthocyanidin (PA). The as-prepared LEC-immobilized BCs (denoted as BC/LECs) were characterized SEM, FTIR, XRD, their dynamic mechanical properties, thermal stability, hydrophilicity assessed. presence LEC was confirmed SEM FTIR analyses. It found that BC/LECs retain three-dimensional (3D) porous network structure BC. still demonstrate favorable hydrophilicity, stability. More importantly, preliminary cell studies suggest show improved over
