Abstract:Attenuated total reflectance spectroscopy was used to study the orientation and deformation of molecular chains in polymers. Reflection and transmission spectra of the polytetrafluorinethylene (PTFE) films were obtained. Parameters of the macromolecule's degree of order were determined for the whole volume and for the surface layer of uniaxially orientated PTFE, and on this basis, we determined the character of dependence l SL (L), where l SL is the effective thickness of the surface layer and L is the film st… Show more
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.
