Two methods for cross-selectivity enhancement of porous poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP)/carbon black (CB) composite-based resistive sensors are provided. The sensors are tested with acetone and ethanol in the presence of humid air. Cross-selectivity is enhanced using two different methods to modify the basic response of the PVDF-HFP/CB sensing platform. https://www.diegojavierfares.com/quick-offer-JOMEED-31-5-Square-Coffee-Table-Modern-Farmhouse-Living-Room-Furniture-Beige-p9138-amazing-deal/
