Neutron Reflectivity from the Monolayer of SAN Random Copolymer

Abstract The detailed structural aspects of the monolayer of SAN random copolymer with 22.6 wt% AN content at the air/water interface were investigated using neutron reflectivity(NR) technique. NR data at various surface pressures were analyzed to obtain the thickness, the density, and the concentration distribution. Well defined double-layered structure could fit the data.
