“…However, there are still few studies on the dispersibility of hyperbranched polymer grafted CB in water. 35,36 In addition, the dispersibility of hyperbranched polymer grafted CB in natural rubber and its effect on the mechanical properties of composite have not been reported. Therefore, we can try to graft the hyperbranched polymer onto CB surface to give the CB good dispersibility in water, and blend the grafted CB dispersion with natural rubber latex by latex blending method to prepare excellent performance rubber-based composites.…”

In order to improve the mechanical properties of rubber-matrix composites, carboxyl-terminated hyperbranched poly (2-hydroxypropane-1,2,3-tricarboxylic acid) grafted carbon black (CB-g-CTHBP) was prepared, and it could be stably dispersed in water for up to 90 days. CB-g-CTHBP dispersion and natural rubber latex were blended to obtain NR/CB-g-CTHBP, and the effect of CB-g-CTHBP content on the mechanical properties of composites was discussed. The results show that the dispersibility and wettability of CB-g-CTHBP to composites are significantly improved after grafting hyperbranched polymer onto the surface. Compared with the composite filled with NR/CB, when the amount of filler is 30 phr, tensile strength, tear strength, and shore A hardness of NR/CB-g-CTHBP increase by 54.78%, 55.13%, and 20.96%, respectively. Moreover, CB-g-CTHBP could disperse more evenly in the natural rubber-matrix, and the interaction between CB-g-CTHBP and rubber-matrix could further enhance in the composite.

“…Otherwise, the adsorption peaks appeared at 1090 cm À1 and 3450 cm À1 in modified CB were attributed to the stretching vibration peaks of C-O and -OH, confirming the successful surface hydroxylation of CB. 35 The results of XPS suggested the existence of carbon and oxygen in CB and modified CB (Fig. S2b, ESI †).…”

“…Due to this reason, an increased content of oxygen is also detected. As shown in Figure B, the C1s spectra of CB are composed of three major peaks at 283.7, 285.1, and 286.2 eV, corresponding to sp2‐hybridized carbon, sp3 C–C bond, and C–O bond, respectively . The O 1s spectrum of CB is indicative of C–O (531.8 eV; see Figure C) .…”

Novel design of alumina foams with three‐dimensional reticular architecture for effective high‐temperature particulate matter capture

Ceramic foams with extensive interconnected pores have great application potential in high‐temperature particulate matter (PM) capture. Considering that there are still challenges to synthesize ceramic foams with efficient filtration, a novel hierarchical‐structured alumina foam with three‐dimensional (3D) reticular architecture has been fabricated via combining chemical grafting pore‐forming agent and polyurethane (PU) foaming technology. Carbon black is grafted with carbamate functional groups in order to enable a better dispersion in highly viscous PU. Submicrometer and micrometer‐sized pores on the cell walls are observed in hierarchical‐structured ceramic foams. The resulting alumina foam exhibits 95.2% removal efficiency for PM particles and low pressure drop of only 50 Pa when grafted carbon black content is 3 wt%. This filtration performance is much higher than that of existing ceramic materials. These features, combined with our experimental design strategy, provide a new insight to design high‐temperature PM filtration materials with durable high performance.
