Abstract:Different carbon black (CB) contents on poly(butylene adipate‐co‐terephthalate) (PBAT)/poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) (P34HB) blends were prepared by melt blending using chain extender (ADR) as compatibilizer. PBAT and P34HB were immiscible, and ADR could react with PBAT and P34HB to improve interfacial adhesion force and molecular entanglement. CB fillers were uniformly and selectively located in the PBAT matrix, and could act as nucleating agent to promote the nucleation of PBAT crystallization… 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.
