How low can you go? Polybenzoxazines can display surface free energies which are even lower than that of pure poly(tetrafluoroethylene). The contact angles and surface free energies were monitored during the polymerizations (see graph for an example). These materials are cheaper to prepare and easier to process than fluoropolymers.
Wer bietet weniger? Polybenzoxazine können niedrigere freie Oberflächenenergien aufweisen als reines Poly(tetrafluorethylen). Während der Polymerisationen wurden die Kontaktwinkel und die freien Oberflächenenergien bestimmt (siehe Beispielkurven). Diese Materialien sind billiger in der Herstellung und leichter verarbeitbar als fluorierte Polymere.
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.
