Abstract
Dissolution and Cellulose-Nylon composites preparation in liquid phase was studied. BMIMCl ionic liquid was synthesized in the laboratory and was used to perform the dissolution purpose. After the dissolution of the polymers, Cellulose and Cellulose-Nylon composite films were prepared and processed. Then the transparency, water absorption and thickness swelling, water vapor permeability and tensile strength of the composite were determined. Further characterization was performed using SEM and FTIR techniques. Results showed that both polymers were compatibly dissolved in Ionic liquid and homogenously blended which indicates chemical bonding was established between the polymers. Transparency, water absorption and thickness swelling decreased and water vapor permeability of the composites increased compared to pure cellulosic film. Also, mechanical strength, Young's modulus and strain at break point of the composite were decreased compared to reference cellulosic film.
