This study is the characterization of a polyurethane derived from vegetable oil for the by extracorporeal artificial heart, using techniques as thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). The proposed objective was to obtain information of the polymer, proving its efficiency as a biomaterial that will be submitted to the working conditions of an extracorporeal heart; thermal stability of the body human temperature (36 -40°C) and mechanical, simulating the functions of a mechanical artificial heart device with extracorporeal oxygenation.
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.
