Transparent and Conductive Graphene Oxide/Poly(ethylene glycol) diacrylate Coatings Obtained by Photopolymerization

Abstract

Water dispersed graphene oxide sheets were used to prepare graphenepolyethylenglycol diacrylate resin composites by photopolymerization. It was found that graphene sheets undergo excellent morphological distribution within the resin system, giving rise to transparent composites with unaltered thermal properties with respect to the neat resin, that are electrically conductive at loading ratios as low as 0.02 %wt of graphene oxide . The proposed strategy based on photopolymerization provides an easy, energy-saving and environmental friendly technique that can find a wide application in coating technology, mainly for electromagnetic shielding and antistatic coatings.

Use of graphite oxide and/or thermally reduced graphite oxide for the removal of dyes from water

“…Differential scanning calorimetry (DSC) was performed on cured films in order to evaluate the glass transition temperature (Tg, Table 2). It is possible to observe an increase of Tg by increasing the filler content into the UV-curable formulations, in accordance with the previous data reported in literature [30], and attributable to an hindering of the mobility of the PEGDA network by the carbonaceous filler with a consequent increase of Tg. Nevertheless, the crosslinked PEGDA films maintained its elastomeric behavior with a Tg values much below room temperature also in the presence of the fillers.…”

“…The UV-curing process was investigated via RT-FTIR analysis; notwithstanding the possible shielding effect of the carbon fillers towards UV-light, the photo-curing process and final acrylic double bond conversion are not significantly affected, and it is possible to achieve fully cured films, as already reported in previous investigation [29][30][31].…”

Graphene oxide nanosheet‐embedded crosslinked poly(ethylene oxide) hydrogel

“…Polymer nanocomposites that include nanofillers have been developed extensively to improve the mechanical strength, thermal and chemical stability, electrical properties, and gas impermeability (barrier properties) of polymeric materials . In general, the properties of polymer nanocomposites are strongly affected by many factors, including the type, size, shape, and content of nanofillers, interactions between the polymer and nanofiller surface, degree of dispersion, and geometry of the nanofiller in the polymer matrix (e.g., alignment) .…”
