Synthesis and Evaluation of Ionic Liquids for their Applications in Antibacterial Paints

Abstract

Thirty six Ionic Liquids were prepared cationic parts were Imidazolium, Pyridinium, Quaternary ammonium and phosphonium with varying chain lengths and anionic parts were Bromide, Sodium Methane sulphonate, Lithium Bis(trifluoromethane-sulfonyl)imide ,Sodium Dichloroacetate and Sodium Tetrafluoroborate ,Potassium Hydrogen sulphate. The prepared ionic liquids were characterized with different characterization techniques TLC, FTIR and NMR. Then these thirty six samples were tested for their antibacterial activity against most commonly occurring bacteria in environment. Most of the ionic liquids show good antibacterial property, among them ionic liquid showing highest antibacterial activity were selected and there different composition were made in paint in order to check antibacterial activity. All compositions were highly antibacterial as all compositions show minimum bacterial growth.
