摘要: Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB)/modified montmorillonite (EMMT) bio-nanocomposites were prepared via melt intercalation method. The thermal stability of the was investigated. results showed that decomposition temperature (T5%) P34HB/EMMT bio-nanocomposite reached 271.4°C, 39.9°C higher than pure P34HB. remarkable enhancement presumably originated from uniform dispersion EMMT in matrix and intercalated structures bio-nanocomposites, which related to increased compatibility P34HB caused by ester group EMMT. TGA-FTIR analysis on degradation procedures manifested introduction did not alter mechanism However, hindered mobility macromolecular slowed down decomposing process POLYM.
