Peradeniya University researchers develop innovative face mask

By Sene Ethulgama

A face mask that could be washed and reused for nearly 28 times has been turned out by researchers of the Peradeniya University making use of Nanotechnology.

The face mask made of cotton material was developed after extensive research.

Last week a Memorandum of Understanding between the Peradeniya University and a private enterprise ” Sarasavi and Isabella ” was reached.

The Face Mask would be put into the market in the next few months.

The price according to the Company who is producing this Technological Mask is around Rs. 200/=

The launching of this Mask which is Trade Marked ” Respirone Nano AV 99 ” was with the invitation of the Minister of Trade Banduala Gunawardene, which event was held in Kandy.

Minister Dr.Banduala Gunawardene said that this may be the most advanced Face Mask that is available in the World.

He said that he would as Minister of Trade and the Minister of the Board of Investment, would propagate the face Mask in collaboration with the Sri Lankan representatives abroad.

He said that from the initial stages he was involved with Professor Gamini Rajapakse who was one of his close contacts.

Prof. Gamini Rjapakse from the Faculty of Science, University of Peradeniya headed the research team.

According to Prof. Rajapakse, this face mask comprises of three layers. The outermost layer is a superhydrophobic cotton layer that repels aerosol particles including droplets that can carry viral particles. The middle layer is also a modified cotton layer with Antiviral, Antibacterial and Mechanical properties and filter air using Electrostatic Filtration. The third and innermost layer is a hydrophilic layer that can absorb and evaporate liquid droplets.

According to the researchers, this face mask can be washed and reused for at least 28 times without compromising the filter quality

The Team involved in this Poject was Professor R.M.Gamini Rajapakse, Consultant Radiologist Dr. Charita Herath, Dr. R.D.S.B.Rajapakse, T.TS.D.Senaratne, M.G.G.S.Tillekratne,and Nanotechnologist Nirosha Samarasinge.
