  • How do plasticizers affect polymer morphology?
  • Among those, adding plasticizer is the simplest and most commonly used way to modify polymer morphology. Plasticizers can weaken intermolecular forces along the polymer chains, thus increasing free volume and lowering the glass transition temperature. For this reason, polymers with plasticizers have improved ductility.
  • How is plasticization achieved in polymer morphology?
  • Plasticization is achieved by incorporating a plasticizer into polymer matrix, copolymerization, or blending. Among those, adding plasticizer is the most common and simplest way to modify polymer morphology. Plasticizer can lessen the intermolecular forces along the polymer chains. As a result, free volume was increased and T g was lowered.
  • 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.
  • How do plasticizers affect film mechanical properties?
  • Plasticizers affect film mechanical properties as well as barrier properties. Fatty acids such as lauric, miristic, palmitic, stearic, and oleic acids have been shown to reduce the WVP of hydroxy propyl methyl cellulose (HPMC) composite films (Jiménez et al., 2010).
  • 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.
  • How to make polymer morphology better?
  • It also lowers the processing temperature, reduces sticking in molds, and enhances wetting. Adding plasticizer, copolymerization, and blending with other polymers are the techniques used to achieve plasticization. Among those, adding plasticizer is the simplest and most commonly used way to modify polymer morphology.
