| Popis: | Stress relaxation is an important parameter factor to determine the applicability of materials under the condition of dynamic loading. We found that soy protein polymer (SPP), a natural polymer, can improve stress relaxation resistance of polyvinyl alcohol (PVOH) films. Such improvement in stress relaxation resistance was accompanied by improved thermal stability. A mechanism of the improved stress relaxation resistance was proposed and was attributed to constructive interactions between SPP and PVOH, which restricted motions and rearrangements of polymeric chains. Such hypothesis was supported by differential scanning calorimetry (DSC) and modeling results in which decreased crystallizability and increased relaxation time for the composites systems were observed. |
