“…In our previous work, tensile strength and tear strength of the XNBR/BCW nano‐composite passed through a maximum at a loading of 13 phr BCWs as the filler content was increased, and were increased by 321% and 155%, respectively. And the elongation at break was almost unchanged.…”

Styrene-butadiene rubber (SBR) nano-composites were prepared through mixing SBR latex with bacterial cellulose whiskers (BCWs). BCWs were extracted from the residual bacterial cellulose (BC) that was treated with acid hydrolysis. A rod-like nanofiber structure of BCWs was observed by transmission electron microscopy and atomic force microscopy. BCWs maintained the crystal structure in BCWs/SBR nano-composites as confirmed by X-ray diffraction patterns. The dispersion of BCWs in SBR matrix was further detected with field emission scan electron microscope.BCWs acted as a multifunctional physical cross-linker in the SBR matrix, the combination of BCW reinforcement and increased effective cross-linking density of the rubber network with incorporating BCWs would cause a more effective transfer of stresses from matrix to filler. Compared with neat SBR, the tensile strength and tear strength of SBR/BCW nano-composite with 2.5 phr (parts per hundred rubber) BCWs were increased by 319% and 182%, respectively.

“…In our previous work, carboxylated acrylonitrile‐butadiene rubber (XNBR)/BCWs vulcanizates were fabricated by mixing BCWs suspension with XNBR latex, followed by coagulating and vulcanization. By introducing BCWs into XNBR, the remarkably enhanced mechanical properties were achieved for vulcanizates . However, to the best of our knowledge, the mechanical responsive behavior induced by water for XNBR–BCWs nanocomposite has not been reported yet.…”

Water-induced mechanically adaptive rubber nanocomposites were prepared by mixing bacterial cellulose whiskers (BCWs) suspension with carboxylated acerlonitrilebutadiene rubber (XNBR) latex, followed by latex blending method. The introduction of BCWs into XNBR enhanced the tensile storage modulus (E') significantly, which originated from the formation of a rigid 3D filler network within matrix as well as the interfacial interaction between filler and matrix. The water uptake ratio of nanocomposite films increased with BCWs content, from 5.5% for neat XNBR to 54% for nanocomposite with 20 phr (parts per hundred rubber) BCWs. Upon submersed in water, the nanocomposite films showed dramatic decrease in E 0 , especially for which filled with high BCWs loadings. For example, E 0 of nanocomposite with 20 phr BCWs was decreased by 98.04% after equilibrium swelling compared with only 52.02% for nanocomposite with 3 phr BCWs. The remarkable watertriggered modulus changes are attributed to the disentanglement of BCWs network after swelling. The prepared XNBR-BCWs nanocomposites with mechanically adaptive properties could contribute to develop the new type of rubber-based smart materials. POLYM. ENG. SCI., 00:000-000, 2018.

The hemihydrate calcium sulfate whisker (HCSW) was modified by γ‐(methacryloxy)propyl trimethoxy silane (KH570) and trimethylolpropane tris(3‐mercaptopropionate) via wet modification and thiol‐ene click reaction, and then the unmodified and modified HCSW were added into α, ω‐dihydroxy polysiloxane (DPS) matrix to prepare silicon rubber composites. After the dual‐surface modification, the surface of HCSW was transformed to hydrophobic, the hydration of whisker was obviously improved, and the whisker dispersed more evenly in the polymer. The mechanical properties, dynamic mechanical properties, and the medium resistance of the silicone rubber composite were compared. The tensile test shows that the silicone rubber shows better mechanical properties after adding the modified whiskers, among which HCSW‐KH570‐SH has the most significant reinforcement effect. Moreover, DPS/HCSW‐KH570‐SH shows the best medium resistance in toluene, gasoline, and water. The addition of modified whiskers can improve the storage modulus of silicone rubber significantly, while DMA and DSC show that the addition of modified whiskers can reduce the glass transition temperature of silicone rubber. The bound rubber indicates that the interface interaction between HCSW‐KH570‐SH and silicone rubber is the best.
