IIT-M develops nano-coated filters for healthcare workers

The nylon-based nano-coated filter uses polymer coating on cellulose paper and was developed using an electro-spinning process.
The coating properties are optimised to efficiently remove sub-micron-sized dust particles in the air.
The filter media is currently being field-tested and once validated through field trials it will be recommended for bulk manufacturing, the researchers have said.
The project is being funded by the Defence Research Development Organisation for its application in defence
K. Arul Prakash, Department of Applied Mechanics, said: “The nano-coating fabricated through the electro-spinning process has fibre diameter less than one micron and can be positioned according to the need to enhance surface/depth filtration for healthcare workers or public responders. This novel filter with multiple nano-coating can filter particles of the order of one-micron size.”
Mr Arul Prakash added, “Nano-coated filter media have much better reverse cleanability behaviour resulting in an extended service life period of air filters, providing prolonged working hours for armoured vehicles. This will save cost for defence applications where the filters are currently imported from developed countries.”
The nano-coated filter media could improve the particle filtration efficiency of face masks, respirator devices, air purification systems in operation theatres, aircraft cabins, armoured vehicle engines, computer hard disk drive filters and pneumatic equipment.
Efforts are also being made to develop composite nano-coated filter media having more than one nanomaterial coating to manufacture multi-layered masks.
