  • How does plasticizer content affect cell morphology in polymer foaming?
  • With the increase of plasticizer content, the cell size of the foam increased from 9.30 μm (10 phr) to 12.75 μm (30 phr), and the expansion ratio increased from 2.33 (10 phr) to 3.36 (30 phr). This work has reference significance for the study of the regulation of cell morphology in the subsequent polymer foaming process.
  • Does EG plasticizer affect the morphology of PVA?
  • It was demonstrated that EG plasticizer exhibited good plasticizing effect, which decreased the melting point and widened the processing window of PVA. Moreover, the plasticizer could affect the melt strength and crystallization of samples, thus, affecting the foaming process and the cell morphology.
  • Why is plasticizer important for high crystallinity polymers?
  • In fact, for high crystallinity polymers, the presence of plasticizer could increase the ability of molecular chains to enter the lattice to a certain extent and promote the ordering of molecules to produce microcrystals when the amount of plasticizer is appropriate or small.
  • Why do PVA foams change morphology after adding plasticizer?
  • As shown at the bottom of Fig. 1, the structure and morphology of PVA foams changed significantly after adding the plasticizer as the original hydrogen bonds of PVA molecules were replaced by forming new hydrogen bonds with EG molecules, which greatly improved the thermoplastic processability.
  • Do PBAT/TPS composite films improve morphology?
  • This study investigated the properties of PBAT/TPS composite films, including starch plasticized using ATBC (10%, 20%) and glycerol (20%, 30%). The films exhibited improved finer morphology, particularly at 30% glycerol concentrations.
  • How does plasticized starch affect thermal processing properties?
  • It's worth noting that the thermal processing properties of starch can be manipulated by its plasticized behavior. Herein, epoxidized soybean oil (ESO) and glycerol were used as the plasticizer for native corn starch and the plasticized starch was integrated with PBAT to manufacture starch-based biodegradable blend films.
