An experimental physicist who coauthored evidence for the polymer brush regime in grafted chains. The collaboration used small-angle neutron scattering on polydimethylsiloxane attached by one end to silicon dioxide. Layer thickness changed with grafting density and solvent quality, showing how neighboring chains force one another to stretch away from a surface.[ref]
Characterization of the brush regime for grafted polymer layers at the solid-liquid interface by P. Auroy and others. Abstract: neutron scattering, end-grafted chains and solvent-dependent thickness scaling
