Probing interaction of charged nanoparticles with uncharged micelles
Abstract
Small-angle neutron scattering (SANS) and dynamic light scattering (DLS) studies have been carried out to study interaction of anionic nanoparticles with uncharged (non-ionic) C12E10 micelles. DLS results show increase in the effective size of nanoparticles on addition of C12E10. Contrast variation SANS confirms the micelles decoration of nanoparticles which is believed to be driven by the hydrogen bonding between them. The number of adsorbed micelles per nanoparticle increases with the increase in the nanoparticle size. Surface number density is also found to be increasing with increase in particle size indicating favored adsorption for larger curvature.
