To
gain knowledge about cause–effect relationships for the
adhesion of ice on surfaces with different chemical groups, we wanted
to study the effect of thin polymer layers on the ice adhesion strength.
To minimize the effect of roughness, smooth substrates that have generally
relatively low ice adhesion strengths were chosen. To be able to obtain
highly reproducible values for the region of low ice adhesion and
to measure small differences of ice adhesion at surfaces with different
chemical compositions, a new measuring system for the determination
of the ice adhesion strength which is based on a modified spin-coater
was developed. We show its technical potential on the basis of first
results on pure silicon wafers and selected hydrophilic polymer layers.
Furthermore, we investigated the effect of the water quality on the
ice adhesion strength. The obtained data are discussed in the context
of physicochemical properties of the layers and of the chemical characteristics
of the used polymers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
