Composite materials produced by particle-bonding with gliadin as a glue [abstract]. American Chemical Society. Paper No. 160. Interpretive Summary: Technical Abstract: In our previous report, we introduced a new methodology for the production of biodegradable polymer composites that will potentially replace existing petroleum-based polymers. Unlike conventional techniques that produce polymer composites by mixing the component materials in the extruder at high temperature, the newly developed particle-bonding technique requires neither extrusion nor processing at high temperatures. Instead, micrometer-scale raw materials are coated with a corn protein, zein, and compressed to form a rigid material. Since this technique does not require purification of raw materials, a broad range of materials can be used as component materials. Wheat protein, gliadin, has similar characteristics as zein but is much cheaper to prepare relative to zein. In this work, the potential for replacement of zein by gliadin was investigated. The mechanical properties produced with these two proteins were found to be similar to each other. |
