Photoactivity of g‐C3N4/S‐Doped Porous Carbon Composite: Synergistic Effect of Composite Formation

“…. A recently developed dispersive force‐based method was used for the synthesis of the composite (Figure S1 in the Supporting Information). Building the composite not only resulted in a synergistic effect on the porosity, surface chemistry, and electrical conductivity, but it also decreased the E g from 2.91 eV (∼430 nm) for g‐C 3 N 4 to 2.79 eV (∼445 nm) for CS/g‐C 3 N 4 (estimated from optical measurements).…”

“…[20] To advance the functional features of g-C 3 N 4 ,w eb uilt its composite with av isible-light photoactive S-doped carbon (CS) derived from ac ommodity polymer,p oly(sodium 4-styrene sulfonate); [21] the composite is referred to as CS/g-C 3 N 4 .g -C 3 N 4 was synthesized from dicyandiamide using the method described in Ref. [22].Arecently developed dispersive forcebased method [23] was used for the synthesis of the composite ( Figure S1 in the Supporting Information). Buildingt he composite not only resultedi nasynergistic effect on the porosity, surfacec hemistry,a nd electrical conductivity,b ut it also decreasedt he E g from 2.91 eV (~430 nm) for g-C 3 N 4 to 2.79 eV (~445 nm) for CS/g-C 3 N 4 (estimated from opticalm easurements).B oth CS and the CS/g-C 3 N 4 show marked photosensitivity and only CS/g-C 3 N 4 reveals av isible-light-driven reduction activity under the cathodic current.…”

Study of matrix–filler interaction through correlations between structural and viscoelastic properties of carbonous‐filler/polymer‐matrix composites

“…The matrix–filler interaction in PMCs is affected significantly by the structure of polymer matrix and the surface characteristics such as area, roughness, and chemical state of filler . Among these, the surface structure of fillers, affecting their dispersion, wettability and agglomeration tendency, governs the overall matrix–filler interaction largely . Presence of surface functional groups has been reported to modify the wettability of the filler, an important parameter determining the matrix–filler interaction significantly .…”

“…Moreover, the arrangement of polymer segments and hence their mobility may be modified by the surface functionalities of the filler, inducing interfacial crystallization of the polymer matrix . Similarly, the matrix–filler interaction is also affected by the matrix structure through interaction between the structural functionalities of matrix and the filler surface functionalities …”

Investigation of the Effects of Polymer Dispersants on Dispersion of GO Nanosheets in Cement Composites and Relative Microstructures/Performances

“…Graphene oxide (GO), a derivative of graphene, not only inherits the structural and property-related features of graphene such as a large surface area and high strength, but also exhibits unique properties such as the presence of a large number of oxygen-rich functional groups and good hydrophilicit [1,2] The unique structure and properties of GO give it potential for use in improving the mechanical properties and durability of cement composites. Recent research has shown that GO can be used to improve cement composite performance.…”
