Nowadays, oily wastewater seriously endangers human health and living environment. Intelligent materials with switchable wettability gear up the broad application prospect in controllable oil/water separation and have received extensive attention. Herein, a simple and novel fluoride‐free method for preparing pH‐responsive super‐wetting material by monomer polymerization is reported. Surprisingly,...
The influence of hydrogen on low cycle fatigue (LCF) of 3.5NiCrMoV steel electrochemically hydrogen charged in the acidified pH 2 0.1 M Na2SO4 solution is studied. In the presence of hydrogen, the fatigue life decreases significantly by ≈70 to ≈80% by: (i) the crack initiation period is decreased; and (ii) the crack growth rate is accelerated. SEM observation indicates that in the presence of hydrogen,...
