A hyperbranched polyimide (HBPI) was synthesized from a designed triamine monomer and the HBPI based memory device presented SRAM (static random access memory) behavior with a low switch voltage and high ON/OFF current ratio.
The synthesized hyperbranched polyimides obtained from a novel tetra-amine have a treelike randomly branched topology with a branch-on-branch structure, which affords a compact, globular molecule.
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.
