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.
GLYCERIN AS PLASTICIZER OF PAN - IGTPAN
Advantages of Glycerin in PAN plasticization: It is one of the most highly known polar substances after water. It has a boiling point above the melting temperature of PAN. Totally soluble in water, which facilitates its removal from the fibers. Low toxicity in relation to solvents used for PAN spinning. Totally biodegradable.
Effect of glycerol plasticizer loading on the physical
Similarly, Chang et al. 99 analyzed the impact of moisture and glycerol on the tapioca starch-based biopolymers and describing the findings that the high content of water, as well as plasticizer

- 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 glycerin a plasticizer?
- It can be observed by the thermal analysis (DSC) that the incorporation of glycerin in PAN as a plasticizer makes the endothermic peak of its fusion visible and quite separated from the exothermic peak of cyclization, with a difference greater than 150 o C, which would not be possible to observe if it was not present.
- Why is glycerine used in PVA plasticization?
- Glycerine (GL), as a traditional plasticizer, is commonly used for PVA plasticization due to its low price and the structure of three-hydroxyl groups . However, a large amount of glycerine tends to leak out during the extrusion process, which is not beneficial for the melt-spinning.
- Can glycerol be used as a plasticizer?
- This study showed that the control AS films were brittle, fragile, and not peelable from the Petri dishes. Hence, the incorporation of glycerol as a plasticizer to AS film-forming solutions led to a decrease in the brittleness, fragility, and increase flexibility and peel ability of AS films.
- Is glycerol a plasticizer for arrowroot starch films?
- Provided by the Springer Nature SharedIt content-sharing initiative This research was set out to explore the development of arrowroot starch (AS) films using glycerol (G) as plasticizer at the ratio of 15, 30, and 45% (w/w, starch basis) using solution casting technique.
- Can glycerol be used in biodegradable food packaging?
- In conclusion, the incorporation of glycerol led to improvements in the overall functioning of arrowroot starch films. In brief, the findings of this research provide insights into the development of biodegradable food packaging.
