Conductive membrane sensor-based temperature and pressure responsive f-polymer dot hydrogels

A thermo-responsive conductive hydrogel membrane (PD-f-Ca2+/Gel) suitable for filtration of cells, water purification, and thermal sensing owing to the volume transition is successfully fabricated. The influence of temperature on the hydrogel changes electronic performance, showing 16.57 mu F cm(-2) and 12.91 mu F cm(-2) at 25 degrees C and 55 degrees C, respectively. Exposing PD-f-Ca2+/Gel to heat promotes volume transition, reducing the pore size of the hydrogel from 12 mu m (25 degrees C) to 2 mu m (45 degrees C). The conductive membrane displayed cell filtration efficiency of 22.96% (25 degrees C) and 71.83% (37 degrees C). Temperature-sensitive membrane sensors exhibit recyclable purification of oil-in-water (efficiency at 24.81%) and bacteria-contaminated water (100% efficiency).

Automated summary

A thermo-responsive conductive hydrogel membrane with volume transition is fabricated for cell filtration, water purification, and thermal sensing. The electronic performance and pore size of the hydrogel can be influenced by temperature, providing different efficiencies for cell filtration and oil-in-water purification.
