Abstract This experimental study was aimed to investigate the microwave absorbing properties of composites with different structures prepared by filling nitrile rubber (NBR) ferrite and acetylene carbon black (CB). The results show that input impedance ferrite-filled composite smaller than CB-filled composites. filled also matched free space better CB composite. two-layer four-layer performed s...

The DLC film was prepared on a nitrile rubber (NBR) elastomer by DC magnetron sputtering (DC-MS), and the sp3 ratio of adjusted changing negative bias voltage applied to substrate. microstructure, composition, tribological properties films deposited NBR substrates were systematically investigated. results reveal that surface can protect reduce roughness NBR. While ranges from 0 V −150 V, conten...

A resorcinol resin/water dispersion and a rubber latex are added to 1% 2,2,6,6,-tetramethylpyperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TEMPO-CNFs) dispersed in water, followed by oven drying at 40 °C for 20 h prepare dried TEMPO-CNF/resorcinol resin/latex (DTRL) mixture with weight ratio of 1/0.5/3. DTRL is then nitrile-butadiene (NBR) or carboxy group-containing NBR (X-NBR) sheet,...
