The article "Bottom-Up Fabrication of PEG Brush on Poly(dimethylsiloxane) for Antifouling Surface Construction" and the article "Constructing Functional Ionic Membrane
Surface by Electrochemically Mediated Atom Transfer Radical Polymerization" show the "grafting from" technique via surface-initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization and surface-initiated atom transfer radical polymerization (SI-ATRP), respectively.
The Pt particles in the ionic membrane
divide into two layers: the deposition layer with a depth of 1-2 [micro]m and the diffusion layer with a depth of 1-20 [micro]m [6, 18].
The membranes so produced were characterized with respect to water uptake, methanol permeability and proton conductivity as a function of temperature in order to emphasizing the effect of the inorganic component on performances of the ionic membranes
. An analysis by X-ray small-angle scattering (SAXS) examination performed on both swollen and dry membranes, provided some insights on the effects of the siloxane domains on the morphology and on the performance of the membranes.
