Abstract: Abstract Hyperbranched polyethyleneimine having 25,000 Da molecular weight was functionalized by a simple sulfopropylation reaction, affording a novel N‐sulfopropylated PEI derivative (PEI‐SO3 −). The successful introduction of N‐sulfopropyl and sulfobetaine groups to the amino groups of… read more here.

DOI: 10.1039/d2ra06919a
Abstract: One of the principal conundrums in drilling operations is addressing wellbore instability caused by shale hydration. Therefore, it is crucial to develop high-performance shale inhibitors. In this work, a hyperbranched polyethyleneimine/graphene composite (HPEI-G) was prepared… read more here.
