Film formation and anti-microbial studies of nano-composite coatings (Joint supervision with Prof. Mahesh Tirumkudulu)

Preventing or
inhibiting the growth of micro-organisms on surfaces is of prime importance in
the healthcare and textile industries. A promising strategy to overcome
microbial growth involves coating the surfaces with materials that can provide
resistance to microbial colonization. Inorganic nano materials and organic
materials with inorganic inclusions are being widely used as anti-microbial
coatings. More recently, water-based organic-inorganic nano-composite materials
are finding applications as functional coatings and specifically as
anti-microbial coatings. However, for effective functioning of these newly
emerging water-based anti-microbial coatings, a thorough understanding on the film
formation and anti-microbial activity is required. In this project, silver
encapsulated water-based polymer coatings will be synthesized and film
formation studies with particular emphasis on “cracking” will be carried out.
Eventually, anti-microbial activity of these coatings will be investigated as
function of the system and drying parameters.
