Abstract
The defiltration performance of the zeolite ZSM-5/liquid system can be effectively modified by sodium hydroxide (NaOH) additive with various concentrations. The infiltration of NaOH aqueous solutions increases the density of silanol (Si-OH) groups on inner surface of the porous ZSM-5, converting the originally hydrophobic surface to hydrophilic and ceasing the liquid outflow. More importantly, the defiltration performance of the system can be adjusted independently without affecting the working pressure of the system. This unique infiltration associated hydrophobic-hydrophilic transition of nanopore surface leads the ZSM-5 based liquid system to an efficient energy absorption system instead of a super-elastic molecular spring.
