Carbon nanomaterial‐based copolymer of styrene–divinylbenzene resins: Efficient interaction through graphene/CNTs polymer network

Abstract

Carbon nanotubes (CNTs) and graphene were separately incorporated into the cross‐linked network of styrene–divinylbenzene composites via in situ suspension polymerization. The prepared copolymers were first chloromethylated and then aminated with trimethylamine to obtain ion exchange resins (IERs). The CNTs‐based and graphene‐based composites exhibited good dispersion throughout the polymer matrix with strong interaction within the network. Remarkable enhancement in antiswelling properties and thermal stabilities confirmed that graphene showed better compatibility and stronger interfacial adhesion than CNTs. The structural and thermal properties of the CNTs‐based and graphene‐based IERs were also significantly improved even at low loadings of 0.4 wt % compared with those when no CNTs and graphene were added. © 2014 Wiley Periodicals, Inc.

The preparation and catalytic performance of graphene-reinforced ion-exchange resins

“…Then PS-DVB-HC showed a major weight loss stage about 70%, which was due to the degradation of the branching chains and crosslinking networks to short chains or volatile compounds induced by oxidative atmosphere. 20,40,41 The third stage weight loss of 20% was assigned to the combustion of char residue of carbonaceous to volatile fragments (such as CO 2 and water), and all the samples completely burnt off at 600 C. In the case of GPNC-IERs, the last stage showed higher amount of char residue compared to the PS-DVB-HC, which was related to the decomposition/ combustion of graphene and the residue of carbonaceous. The extrapolated degradation onset temperatures (T d ) and the temperature of the maximum weight loss rate (T max1 and T max2 ) in Table 3 showed the effect of graphene content on the degradation behavior and thermal stability of the GPNC-IERs.…”

“…Recently, graphene has played an important role in nanoscience owning to its exceptional mechanical, electrical, chemical and thermal properties. [18][19][20][21] Its mechanical strength is comparable to that of CNTs and the two-dimensional honeycomb layer of sp 2 -bonded structure has potential applications in many elds as composite materials, energy storage and conversion, sensors and nanoscale electronic components, etc. Recent studies have reported that the scalable production cost of graphene sheets in large quantities could be much lower than CNTs, which might rival the CNTs in many technological applications.…”

“…The EO conversion and MEG selectivity for 0.4-GEP-HC exhibited better performance at a range of 90-102 C. These results indicate that the enhancement in properties and reactive performance of graphene-based nanocomposites is markedly superior to the effect of the CNTs in the polymer matrix. 20 The long-time run of the IER catalysts in the hydration of EO at 98 C was carried out for 500 h on stream, and the results were plotted in Fig. 11.…”

“…In condensed matter physics, the application of the derivation methods is also a very efficient tool. In addition, the results obtained in this paper may also lay the groundwork for the further research on graphene networks [28], the structures of some non‐metallic crystals [29] or the carbon nano‐tubes [30] and so on.…”
