Surface behaviour of PMMA: Is gel cleaning the way to go?

The article presents a study on the use of aqueous polymer gel as a means of controlling solvent diffusion and reducing mechanical damage during treatment of Poly (methyl methacrylate) PMMA. Topics discussed include ability of Gellan gels to partially remove artificial soil from the surface of PMMA samples with propanol gel removing more soil than hydrogel, gravimetric analysis of PMMA sample after application of Polyvinyl acetate (PVAc)/Borax gel, and removal of sodium dodecyl sulfate (SDS) monolayer from the surface after applying PVAc/Borax hydrogel. Also included is a graph showing sum frequency generation (SFG) spectra for PMMA films and a conclusion that Gellan gels were more effective in removing artificial soil than PVA gels.
