Properties of Waterborne Polyurethane/ Functionalized Graphene Sheet Nanocomposites Prepared by an in situ Method
TL;DR: In this paper, a nanocomposites of waterborne polyurethane (WPU) with functionalized graphene sheets (FGS) were prepared by an in situ method.
Journal ArticleDOI
Morphological and physical properties of a thermoplastic polyurethane reinforced with functionalized graphene sheet
TL;DR: In this article, a polyurethane/functionalized graphene sheet (FGS) was used as a nanofiller in the preparation of polymer nanocomposites, and the results showed that FGS has a high affinity for TPU, and it could therefore be used effectively in preparation of TPU/FGS nanocompositionites without any further chemical surface treatment.

TL;DR: In this article, graphite oxides (GOs) at various oxidation states were examined as fire retardants of epoxy resins, and it was shown that the fine dispersion and disordering of layered structure of GO by the intercalation of the epoxy molecules into the gallery of GO also reduced the intumescent ability, and the fire retardant effects of GO.
Journal ArticleDOI
Preparation and Physical Properties of Waterborne Polyurethane/Functionalized Graphene Sheet Nanocomposites
TL;DR: In this paper, a nanocomposite of waterborne polyurethane (WPU) was prepared with functionalized graphene sheets (FGSs), which are a new type of nano-sized conductive filler.
Journal ArticleDOI
Synthesis and Characterization of Novel Polyurethanes Based on 4-{(4-Hydroxyphenyl)iminomethyl}phenol
TL;DR: In this paper, four novel polyurethanes were prepared from 4-{(4-hydroxyphenyl)iminomethyl}phenol by reactions with two aromatic diisocyanates, 4,4′-diphenylmethane diiscyanate and toluene 2,4-diisocynate, and two aliphatic diiscynate.
