Question
What is the main application of the optically active
biodegradable nanocomposite film developed by researchers at the Institute of Advanced Study in Science and Technology (IASST)?Solution
Researchers have fabricated an optically active biodegradable nanocomposite film with excellent mechanical properties that can be used as a stretchable optical devices like flexible display, flexible organic LED, etc. Numerous methodologies have been adopted to improve the properties of polymeric materials by using suitable nanomaterials. The nanomaterials are known to enhance the properties of the polymers keeping the inherent properties of the polymers intact. Scientists have reported that polyvinyl alcohol (PVA) is one of the most widely studied synthetic biodegradable polymers having good film-forming and excellent mechanical properties. A research group from physical sciences division of the Institute of Advanced Study in Science and Technology (IASST), Guwahati, an autonomous institute of North-East India under the Department of Science and Technology (DST), fabricated a biodegradable PVA-CuO nanocomposite film using a facile solution casting technique, where Cu salt used as a precursor for the in-situ CuO nanoparticles formation under different heat treatment. This research group is led by Dr. Sarathi Kundu, Associate Professor, along with Mr. Saiyad Akhirul Ali, working as a Junior Research Fellow (JRF).
