Determination of graft density of substrate-supported polymer films
Abstract
Determining the graft density of polymers adsorbed on a substrate from neutron scattering-length density profile can be challenging. A scheme based on integrating a select region of the profile is proposed and applied to results obtained from a recent neutron reflectometry experiment that investigated the physical properties of polyethylene oxide (PEO) chemisorbed onto a gold-coated Si substrate. Reflectivity measurements were performed with …
