| Abstract | This study aims to alter the drawbacks of starch-based foam that include poor mechanical properties and high waterabsorption. Biodegradable cassava-starch cushion foams were prepared successfully by compression. Kaolin was selected as areinforcing agent as well as a water resistance additive. All of the prepared foams showed a smooth and dense outer surface withhigh open-cell content inside. Elongation at break of the foams decreased (from 7.1 to 2.6%), while the bending modulus increasedfrom 66 to 112 MPa with increasing kaolin content from 0 to 15 phr. The melting temperature and the glass transition of the foamdecreased from 156 to 150 ?C and from 62 to 60 ?C, respectively, after the addition of kaolin at 15 phr. At 100% RH, the additionof 15 phr of kaolin could reduce the equilibrium moisture content of the foam by 22% and the foam can be assimilated into theenvironment within a short period of time. |
