    Basic Information

Technology developed: Superhydrophobic coating for potential face mask (TP19762251325)
Category: Product (Hardware/Material/Software)
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Uttam Manna and Sachin Kumar Indian Institute of Technology Guwahati CHEMISTRY AND NANOTECHNOLOGY Associate Professor
Technical Application Area: Healthcare
If 'Other', please specify:
These materials are useful in various applications including face mask to protect from aqeouse dropl
Please give more details of new technical application area:
These materials are useful in various applications including face mask to protect from aqeouse droplets oil water separation and selfcleanable smar textile the present invention provides a method of preparing a disposable water repellent mask by preparing superhydrophobic coatings on wide range of fibrous substrates which includes regular hydrophilic masks and tissue papers which provides stability to the masks and prevents penetration of water droplets that carries infectious agents Furthermore the disposable mask will also avoid splashing of body fluids and droplet infections with respiratory pathogens It can be sued to develope self cleanable smart textile

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
