“…Compared with unfilled XNBR, the value of Q for X‐hANFs7 decreases by 17%, and V e increases by 35%. The hANFs can play role of the physical crosslink points via interfacial hydrogen bonding interaction between XNBR matrix and filler, which results in the increase of crosslink density and decrease of swelling ratios of XNBR nanocomposites …”

Water‐dispersible hydrolyzed Kevlar nanofibers (hANFs) prepared by acid‐assisted hydrothermal treatments of Kevlar nanofibers (ANFs) were first incorporated into carboxylated acrylonitrile butadiene rubber (XNBR) by a latex co‐coagulation method. The obtained hANFs maintained the one‐dimensional nanofibrous morphology and crystal structure as ANFs. There were amounts of polar groups appearing at the end of hANFs molecular chains after hydrothermal process, which led to the strong hydrogen bonding interaction between the filler and XNBR matrix. The results indicated that hANFs had significant reinforcement effects on the mechanical properties, crosslink density, and thermal stability of XNBR matrix. In comparison with those of neat XNBR, the tensile strength, tear strength, crosslink density, and maximum heat decomposition temperature (Tmax) of XNBR/hANFs nanocomposites filled with 7 phr hANFs increased by 236%, 161%, 35%, and 19.64 °C, respectively. © 2019 Wiley Periodicals, Inc.

The Mg 2 B 2 O 5 w modified by toluene-2, 4-diisocyanate (TDI) and fatty amine (n-dodecylamine(D) or n-octadecylamine (O)) was used in oil-containing monomer casting (OMC) nylon, and the effect of modified Mg 2 B 2 O 5 w on mechanical and friction properties of OMC nylon composites was investigated. The significant improvement of the mechanical and friction properties of composites was observed. The addition of 0.15 wt% TDI-D-Mg 2 B 2 O 5 w or TDI-O-Mg 2 B 2 O 5 w resulted in 21 and 20% growth in the tensile strength, 53 and 52% increase in the flexural strength, respectively. Additionally, nearly 60 and 58% reduction in the friction coefficient, about 84 and 80% decrease in the abrasion quantity. Furthermore, the worn surface of composites exhibited smooth, which confirmed the antiwear effect of Mg 2 B 2 O 5 w. The improvement was attributed to the interfacial adhesion between whiskers and matrix by hydrogen bonds. This work provided a facile approach to the design of wear-resistant polymer composites that hold significant potential in construction machinery industry.

Reduced graphene oxide (rGO) with various surface structures was prepared by reducing graphene oxide (GO) with hydrazine hydrate (N 2 H 4 ), sodium borohydride (NaBH 4 ) and L-ascorbic acid, respectively. The resulting rGO were used to fabricate rGO/polypropylene (PP) nanocomposites by a melt-blending method. The surface structure of rGO as well as multifunctional properties of rGO/PP nanocomposites were thoroughly investigated. It was shown that rGO with highest C/O ratio could be obtained by reducing GO with N 2 H 4 . The crystallization behaviors, tensile strength, thermal conductivity and thermal stability of rGO/PP nanocomposites were significantly improved with the increase of C/O ratio of rGO. For example, with only 1 phr (parts per hundred PP) rGO reduced by N 2 H 4 , the degree of crystallinity, tensile strength, maximum heat decomposition temperature and thermal conductivity of PP nanocomposite were increased by 6.2%, 20.5%, 48.0 ∘ C and 54.5%, respectively, compared with those of pure PP. Moreover, the thermal degradation kinetics indicated that the decomposition activation energy of rGO/PP nanocomposites could be enhanced by adding rGO with higher C/O ratio.
