Title : Seaweed polymer containing functional materials to protect environment


India has ~7500 km long coastline that is accessible for seaweed activities including seaweed cultivation. Seaweeds represent one of the most significant and auspicious sources for numerous natural products including gelling polymers. Moreover, seaweed polymers have been widely used as a key ingredient in the pharmaceutical, food, cosmetics, and dairy industries as a stabiliser. In recent, I have developed green processes for the production of these seaweed polymers under the value addition program of Indian seaweed biomass.

The synthesis of functional materials using seaweed-derived polymers for potential applications is demanding research in the modern era. These functional materials are of great importance owing to their biodegradability, catalytic property, excellent bioactivity, and less toxicity. In this direction, we have developed green and eco-friendly methods for designing seaweed polymer containing functional/smart materials for potential uses such as self-healable emollients, biodegradable packaging, sensors, bioactive compositions, and catalysts. These developed materials are characterized using advanced analytical tools such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), FTIR, NMR, XRD. This short talk provides the progress towards the preparation of seaweed polymer containing functional /smart materials for various applications.
