Design and environmental applications of polyoxometalate-ionic liquid (POM-IL)-based molecular and composite materials
Abstract
Polyoxometalate-based molecular and composite materials were investigated for eco-friendly sustainability concerns like acid corrosion protection and water purification. A comprehensive literature investigation on the classical and non-classical roles of counter-cations in polyoxometalate (POM) chemistry was also achieved. One principal project deals with the investigation of POM based ionic liquids (POM-ILs) as transparent and highly viscous coatings to prevent the corrosion of different typical mineral stones with different elemental composition and porosity. Corrosion caused by acid rain and biodeterioration from bacterial films are worldwide problems for building construction or preservation of cultural heritage objects such as statues and sculptures. The project demonstrates how typical building stones can be protected from weathering and biofilm formation by application of thin films of monolacunary Keggin POM {SiW11} -based water-repellent ionic liquids (POM-ILs). Exposure of the stones samples to simulated acid rain showed negligible corrosion compared to the major deterioration of the uncoated samples and the biocidal properties of the POM-ILs inhibited the formation of microbial films on coated stone slabs. This class of bifunctional modular molecular materials could also be developed for usage in building construction, cultural heritage conservation and environmental protection. The acid-stable surface coating was observed to be mechanically stable and is not…
