Pa6 polymerization
WebJun 22, 2016 · The key factor that limits the thermal conductivity is graphene agglomeration as well as the incompatible interface between graphene and polymer. Here, we report super-high thermal conductivity of polyamide-6 (PA6) composites achieved by adding small amounts of graphene oxide (GO)-stabilized graphene dispersions (graphene-GO). WebSep 3, 2024 · Specifically, a hydroxyl concentration above 0.2 mmol OH·g −1 leads to a slowdown of the PA6 polymerization reaction. This reaction can be completely inhibited when the hydroxyl concentration reaches 0.77 mmol OH·g −1 as in the case of fully rehydroxylated particles or pristine raw particles.
