Abstract:This paper reported the process of causing piezoelectricity to amorphous stereocomplex poly (lactic acid) using microwaves. From finite element analysis results of microwave irradiation from the constructed resonator to the film, it was found that microwave with an electric field strength of 7 MV m−1 was applied to the film at the incident power of 200 W. The microwave instantaneously heated the film, and at the same time, a DC voltage was applied to the film to inject an electric charge into the film and crea… 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.
