New polymer material for the packaging industry
Inorder to protect items from extreme environmental conditions, an Indian research team has developed a biodegradable, non-toxic polymer. This polymer might be utilised as a packaging material.
Chitosan, a polysaccharide derived from shellfish such as crab, lobster, and shrimp, was used to make the polymer from guar gum. High water stability and mechanical strength, as well as good resistance to extreme environmental conditions, have been discovered in this substance.
For packaging, polysaccharides are excellent biopolymers to utilise. They are, however, not the favoured choice due to a number of disadvantages, including poor mechanical qualities, excessive water solubility, and poor barrier properties.
This new study by Associate Professor Devasish Chowdhury and Junior Research Fellow Sazzadur Rahman of the Institute for Advanced Study in Technology, Paschim Boragaon, Garchuk in Guwahati has overcome these challenges by fabricating a cross-linked polysaccharide using a technique known as the solution casting method. They were funded by the Department of Science and Technology.
A 10-day test revealed that the substance remained insoluble in water. Guar gum-chitosan crosslinked composite film had good mechanical strength and was water repellent or hydrophobic with low vapour permeability.
The cross-linked guar gum-chitosan material's exceptional mechanical strength, water repellency, and tolerance to extreme environmental conditions improve its packaging application potential, according to the researchers. Carbohydrate Polymer Technologies and Applications, a scientific publication, has published their findings. Achyut Konwar and Gitanjali Majumdar were on the research team.
