Lamination of Chitin-Cellulose Film and Thermoplastic Starch

Abstract:

In this study, chitin-cellulose films (CC) and nanocomposite (NC) films were successfully laminated to thermoplastic starch (TPS). These were prepared using adhesive, controlled heated compression, and heated compression with adhesive. Lamination was investigated by utilizing direct tensile adhesion strength test to acquire the adhesion strength between the two layers. The highest adhesion strength of 0.502±0.036 MPa resulted for CC/TPS. Combination of failure at the interface and substrate was observed for most CC/TPS laminates. FTIR spectra indicated presence of -NH groups from chitin and -OH groups from starch and cellulose that could improve interfacial adhesion by hydrogen bonding. Scanning Electron Micrographs (SEM) showed a rough surface of chitin-cellulose films, and the clear continuity of CC film with TPS. An increase in modulus from from 0.342 ± 0.020 MPa for TPS to 1.059 ± 0.162 for CC/TPS and 0.939 ± 0.143 MPa for NC/TPS.
