Effect of Formamide on the Mechanical Properties of Thermoplastic Protein Films

Abstract:

To manufacture the biodegradable protein films available for potential environmentally friendly application, down feather fiber was prepared and modified by formamide which acts as a plasticizer and then hot-pressed into films. The influence of formamdie on the mechanical properties of thermoplastic down films was investigated. The protein films modified by formamide were tough and showed excellent mechanical properties compared to the films without formamide. The down thermoplastic films modified by formamide showed lower weight loss of formamide indicating formamide is a good plasticizer for protein application.
