Direct measurement of surface forces has revealed that silica surfaces seem to have a short-range repulsion that is not accounted for in classical DLVO theory. The two leading hypotheses for the origin of the non-DLVO force are (i) structuring of water at the silica interface or (ii) water penetrati

The interaction forces between silica and plasma-treated polypropylene surfaces in aqueous NaCl solutions have been measured using a scanning force microscope. The measured interaction forces are well described by DLVO theory at large and moderate separation distances. However, at short range (<5 nm
The effect of a cationic polyelectrolyte, PCMA, on the forces between two cellulose surfaces and between one cellulose surface and one mica surface has been studied using the interferometric surface force apparatus (SFA). The cellulose surfaces were prepared by Langmuir-Blodgett deposition of trimet
