Natural-based plasticizers and biopolymer films: A review
Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) [12], [13]. The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary forces among them.
Effect of glycerol plasticizer loading on the physical

Interaction between Polyacrylonitrile (PAN) and Plasticizer
Ionic liquid, as a green solvent, has been widely used in high-tech fields. One of the uses is an excellent plasticizer for polymers, and a good plasticizing effect can be achieved for these
- Can glycerin be used as a primary plasticizer?
- This innovative technology enables spinning by melting PAN polymer by using glycerin as the primary plasticizer, avoiding the use of highly toxic solvents. In the present work, PAN copolymer was copolymerized by conventional aqueous suspension. Its characterization was performed by FT-IR, GPC and DSC analysis.
- Can glycerin be used as a polymer electrolyte?
- Copper-ion conducting gel polymer electrolyte (GPE) systems based on polymer poly (vinyl alcohol) (PVA) and copper sulphate salt doped with glycerin as plasticizer have been synthesized by using solution casting technique. Differential scanning calorimetry (DSC) is used to examine the thermal effect of glycerin on a polymer electrolyte.
- What are the advantages of using glycerin in Pan plasticization?
- Another great advantage of employing glycerin in PAN plasticization is because it is very soluble in water, it can be easily removed from the fibers by washing, restoring the fibers to the same composition as the original copolymer, as if they were produced by wet or dry spinning. This way these fibers are suitable for producing carbon fiber.
- Is glycerol a plasticizer?
- This paper portrays the existing connection between glycerol and the polymer industry, particularly as a feedstock for polymer synthesis and its role as a plasticizer in the starch polymer.
- Can glycerin be used to extrude PAN fibers?
- Nowadays, the extrusion process of PAN fibers shows potential of cost reduction in relation to the wet spinning method. This innovative technology enables spinning by melting PAN polymer by using glycerin as the primary plasticizer, avoiding the use of highly toxic solvents.
- Does glycerin concentration affect thermal degradation of polymer electrolyte?
- From TGA curves, it is observed that thermal degradation of the glycerin doped polymer electrolyte is shifted towards lower temperature when compared to pristine PVA and the weight loss of the polymer electrolyte increases with increase of glycerin concentration.
