Citation: Jong, L. 2008. Reinforcement Effect of Soy Protein and Carbohydrates in Polymer Composites. In: Cheng, H.N., Gross, R.A., editors. Polymer Biocatalysis and Biomaterials II. ACS Symposium Series No. 999. Washington, DC: American Chemical Society. p. 86-108. Technical Abstract: The modulus of soft polymer material can be increased by filler reinforcement. A review of using soy protein and carbohydrates as alternative renewable reinforcement material is presented here. Dry soy protein and carbohydrates are rigid and can form strong filler networks through hydrogen-bonding and ionic interactions. They are also capable of interacting with polymers that possess ionic- and hydrogen-bonding groups. Through filler-filler and filler-rubber interactions, the rubber modulus is significantly increased. The variables in the reinforcement effect include the compositions of both soy protein and carbohydrate, polymer composition, particle sizes of dispersions, and co-fillers.
