Our Faculty


Ashwini Kumar Agrawal

Institute Chair Professor & Head of the Department

Ph.D. (U. Rochester, NY, USA)
Dr. Ashwini K. Agrawal is Professor at the Department of Textile Technology, Indian Institute of Technology (IIT), Delhi. He is also an alumnus of this institute and graduated with silver medal from IIT Delhi in 1986 after completing his B. Tech. degree in Textile Technology. He obtained M.S. and Ph.D. degrees in Chemical Engineering from the University of Rochester, Rochester, New York, USA in 1992. He returned to his almamater in 1995 as a faculty after working in the US. His main areas of teaching and research interest are smart and intelligent textile materials, nano-materials, plasma processing, and fiber manufacturing.

Teaching Interests

Atmospheric pressure plasma processing

The research group is involved in modification/functionalization of polymeric/textile substrates using indigenously developed atmospheric pressure glow discharge plasma reactor. Among the available surface modification techniques, plasma technology is gaining interest due its ecological and economical advantages over conventional chemical processing of textiles.


Advanced Fibres and Films

Conventional fibres have long been used for traditional textile applications. In the 21st century, with the advent of nanomaterials the area of composite materials opened up. Nanomaterials, such as ZnO nanorods have enhanced the tensile strength of nylon by ~400%, and imparted functionality to the fibre itself without additional post-processing.


Nanofibres impart interesting properties to the electrospun material which are not present at the micro scale due to the high surface area to volume ratio. Electrospinning parameters have been studied and controlled to achieve desired dimensions. Nanowebs and nanofibres of PVA, PGA, PAN, etc. have been created for applications ranging from tissue engineering to filtration.

Responsive Materials

Materials that change one or more properties significantly in a predictable fashion by external stimuli like stress, temperature, pH, electric or magnetic fields are popularly called smart and responsive materials. In the past, we have worked on shear reversible alumina gel, microencapsulation of phase change material among others. 

Speciality Finishes and Coatings
Finishing processes are an excellent way to impart desired properties to pre-existing textiles. In our group, antimicrobial properties have been imparted to cotton using silver nanoparticles and Janus particles, self cleaning properties by using titania aqueous nanosol and superhydrophobic properties using nanoemulsion polymerization techniques.


Flexible Electronics

The leaps in the electronics sector has revolutionized our world with their inalienable presence in our everyday life. However, the rectangular shape of the batteries in these devices restricts the possibilities of their adaptation in textiles and wearable electronics. Thus, a major caveat in the research of flexible electronic devices like flexible batteries, supercapacitors and PV cells is the availability of flexible conductors with adequate conductivity to replace rigid foils and semi-flexible films.
