Abstract: The non-isothermal crystallization behavior of ethylene-tetrafluoroethylene (ETFE) copolymer was investigated by DSC and imaging FTIR analysis. Modified non-isothermal Avrami analysis was applied to interpret the crystallization behavior of ETFE. It was found that the less linearity in ln[-ln(1-X(t))] vs. ln(t) plot was obtained in thermal analysis comparison with imaging FTIR due to relatively small crystallization enthalpy change in ETFE. It means that imaging FTIR measured by overall IR absorptio…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
