The objective of the present work was to study the preparation of a novel bio-based product from gelatin (GT) and natural
rubber (NR) using potassium persulphate (KPS) as an initiator. The GT and NR composites (GT/NR composites) containing KPS were formed in an aqueous latex solution. The chemical structure of the GT/NR composite was characterized by
ATR-FTIR, and XRD. The highest tensile strength was observed in a 9/1 GT/NR composite and the elongation at break of
this composite was improved by the addition of both NR and glycerol. In addition, the swelling ratio increased as a function of increasing GT content in the composite. The thermal stability of the GT was improved after the formation of the
chemical interaction between the NR and GT helped by the KPS. The best ratio of the GT/NR composite was 3/7 GT/NR.
This environmentally friendly composite easily decomposed in natural soil within 30 days. The novel biopolymer showed
high mechanical properties, water resistance and was produced in an environmentally compatible process. The NR was able
to improve some of the physical and mechanical properties of GT biofilms produced from the composite. Possible future
applications of this composite are for medical materials, and the packaging and life extension of food products.
