Published in 2020 at "European Polymer Journal"

DOI: 10.1016/j.eurpolymj.2020.109545

Abstract: Abstract In this study, poly(urea formaldehyde) (PUF) nanocapsules with epoxy cores were blended into a polyurea matrix, formulated as poly[(phenyl isocyanate)–co-formaldehyde] (PMDI) (f = 3.4), and a diamine curing agent (VERSALINK 650) to form nanocomposites. The nanocomposites… read more here.
