Hydrogel UPSC NOTE

 Why in News

  • Researchers at the Indian Institute of Science (IISc) have designed a sustainable hydrogel to remove microplastics from water

  • The hydrogel developed by the team consists of three different polymer layers – chitosan, polyvinyl alcohol and polyaniline – intertwined together, making an interpenetrating polymer network (IPN) architecture.

  • The team infused this matrix with nanoclusters of a material called copper substitute polyoxometalate (Cu-POM)

Why in News

  • These nanoclusters are catalysts that can use UV light to degrade the microplastics

  • The combination of the polymers and nanoclusters resulted in a strong hydrogel with the ability to adsorb and degrade large amounts of microplastics. 

  • The team found that the hydrogel could remove about 95% and 93% of two types of microplastics in water.

  • A hydrogel is a biphasic material, a mixture of porous, permeable solids and at least 10% by weight or volume of interstitial fluid composed completely or mainly by water.

  • In hydrogels the porous permeable solid is a water insoluble three dimensional network of natural or synthetic polymers and a fluid, having absorbed a large amount of water or biological fluids.

  • These properties underpin several applications, especially in the biomedical area

  • Many hydrogels are synthetic, but some are derived from nature.

  • Microplastics pose a great threat to health as these tiny plastic debris can enter our bodies through the water we drink and increase the risk of illnesses

  • Scientists have previously tried using filtering membranes to remove microplastics. 

  • However, the membranes can become clogged with these tiny particles, rendering them unsustainable.

  • The newly developed hydrogel usage will have solution to these issues as well
