the muscle-like technology would be of enormous advantages for biomedical applications such as medical implants and human assist devices. ionic polymer metal composites (ipmcs) are one kind of biomimetic actuators. an ionic polymer metal composite composed from an ionomer with high ion exchange capacity that packed between two thin metal layers. in the present study we focused on the preparatio...

The gas-liquid membrane contactor (GLMC) is a promising alternative gas absorption/desorption configuration for effective carbon dioxide (CO2 ) capture. The physicochemical properties of membranes may synergistically affect GLMC performances, especially during the long-term operations. In this work, commercial polypropylene (PP) and polyvinylidene fluoride (PVDF) hollow fiber (HF) membranes wer...

In recent decades, membrane-based processes have been extensively applied to a wide range of industrial processes, including gas separation, food industry, drug purification, and wastewater treatment. Membrane distillation is thermally driven separation process, in which only vapour molecules transfer through microporous hydrophobic membrane. At the operational level, performance membrane negat...
