“…So this rise was mainly attributed to the physical interaction of RH with filler. The hydrogen bond of RH/NCC has been verified in our previous publications [28]. It could be deduced that, with the existence of RH, NCC network seemed to be enhanced by hydrogen bond via RH.…”

Abstract.A series of nanocrystalline cellulose (NCC) reinforced natural rubber/butadiene rubber/styrene-butadiene rubber (NR/BR/SBR) blends were prepared via mastication of NR/NCC, BR/SBR and other ingredients. Resorcinol and hexamethylene tetramine (RH) was adopted to modify the interface between NCC and rubber matrix. The morphology, dynamic viscoelastic behavior, apparent crosslink density, mechanical performance and dynamic mechanical property of NR/BR/SBR/NCC blends were discussed in detail. The results showed that NCC was uniformly dispersed in composites and RH could enhance the adhesion of NCC and matrix. According to the dynamic mechanical analysis, NCC performed comparable reinforcing effect with carbon black (CB), and the modulus was improved with modification of RH. Mechanical tests showed that the replacement of CB by NCC in the blends did not deteriorate mechanical properties of composites. Besides, the blends exhibited best mechanical properties, when 10 phr NCC substituted CB.

“…The FT‐IR profiles of the modified membranes show an increase in the intensity of the broad peak at 3000–3500 cm −1 , which originates from the aliphatic secondary amino groups of PDDA and the OH stretching of CNC in Nafion‐[PDDA/CNC] 20. In addition, new peaks appeared at 2921 and 2850 cm −1 , corresponding to the CH 2 stretching of PDDA and CNC . The FT‐IR data clearly show that PDDA and CNC accumulate in Nafion‐[PDDA/CNC] 20 .…”

Vanadium redox flow batteries (VRFB) have been widely used as grid-scale energy storage systems because of their many advantages, such as moderate operating conditions, large-scale capacity, long cycle life, and relative safety. Despite these advantages, VRFBs suffer from the critical problem of electrolyte contamination due to vanadium ion crossover through the separator (Nafion 212), with consequent capacity decay during cycling. In this study, to reduce the crossover of vanadium ions, Nafion 212 was modified with polydiallyldimethylammonium chloride (PDDA) and cellulose nanocrystals (CNC) via a layer-by-layer process. Nafion-[PDDA/CNC] n was stacked to a thickness of 8.92 nm per layer (n = 1). As the stacking number, n, increased, the area resistance increased exponentially, indicative of degradation of the cell performance due to an increase in the mass transfer resistance. Nevertheless, the resistance against self-discharge, which is measured in terms of the change in the open circuit voltage (OCV), was dramatically enhanced as a function of the number of stacking layers; the OCV was maintained for up to 150 h due to restriction of vanadium ion crossover. Thus, the optimum stacking number for maximizing the cell performance is twenty (Nafion-[PDDA/CNC] 20 ) based on the trade-off effect between degradation of the membrane permeability and increased resistance.

“…The results indicated that the cross-link density was related to the state of PF coating. At 100 °C, SiCB was coated uniformly with a thin layer of PF, which provided a stronger interaction through chemical bonds with NR molecular chains [30], leading to improved cross-link density. Therefore, PF can strengthen the interfacial bonding and link more closely between rubber and filler.…”

For the first time, phenolic formaldehyde resin (PF)-treated silica carbon black (SiCB) were prepared with different treatment conditions and their effect as fillers on the mechanical properties of filler filled natural rubber/butadiene rubber (NR/BR) composites were investigated in detail. The PF coating layer on the SiCB derived from rusk husk not only promoted the dispersion of the fillers but also improved the interfacial interactions between fillers and the rubber matrix. As a result, both the cross-link density and mechanical properties of the obtained composites were effectively enhanced. The filler SiCB with 3 wt % PF surface treatment greatly improved the tensile strength of NR/BR composites and reached 7.1 MPa, which increased by 73.7% compared with that of SiCB-filled NR/BR composites. The improved interfacial interactions promoted higher energy dissipation, leading to simultaneously enhancing the glass transition temperature of the obtained composites. Due to the easy processing and low cost of filler as well as the effectively enhanced mechanical properties of composites, the PF-coating methodology has a great potential for practical applications in SiCB reinforced high-performance composites. A commercial filler, carbon black (N774), was also used in this study and evaluated under the same conditions for comparison.
