Abstract
Xanthan gum (X)-incorporated natural rubber (NR) cast films were fabricated from blocked NR by solvent casting method using dichloromethane as the solvent. The rather smooth films were obtained. X markedly promoted both of water sorption and erosion in phosphate buffer pH 7.4 of these composite films. With increasing X amount also significantly enhanced the film tensile strength, Young’s modulus and area under the curve while did not affect contact angle of water/formamide and surface free energy. 30%X-loaded NR films exhibited the highest durability with apparently high water sorption and erosion for further using such as wound dressing.
