제목 Preparaion and Properties of Waterborne Poly(urethane-urea)s/Graphene Nanocomposites
초록 Nanocomposites of waterborne poly(urethane-urea)s (WBPUs) with graphene (contents: 0, 3, 5, 7 wt %, respectively) were prepared by an in situ method. WBPUs (pristine WBPUs: WBPU-19 and WBPU-24, fixed soft segment content: 60 wt%) containing dimethylol propionic acid (DMPA)/ethylene diamine (EDA) contents (19/16.8 and 24/11.4 mol %) were prepared from 4,4-dicyclohexylmethane diisocyanate (H12MDI), poly (tetramethylene ether) glycol (PTMG, Mn=2000), dimethylol propionic acid (DMPA) and ethylene diamine (EDA) as chain extenders.. This study focused on the effects of graphene content on the dynamic thermal and mechanical properties, hardness, tensile properties and conductivity.
