Wyart et al. [ 104] prepared a series of pseudobrushes by simultaneous adsorption of hydroxy-terminated PDMS onto a silicon wafer surface and reported that the dried thickness of these layers obeyed the scaling law of where

Chemical Grafting. Polymer chains which are soluble in the suspending Hquid may be grafted to the particle surface to provide steric stabilization. The most common technique is the reaction of an organic silyl chloride or an organic titanate with surface hydroxyl groups in a nonaqueous solvent. For typical interparticle potentials and a particle diameter of 10 p.m, steric stabilization can be provided by a soluble polymer layer having a thickness of - 10 nm. This can be provided by a polymer tail with a molar mass of 10 kg/mol (25) (see Dispersants).
