▎ 摘　　要

NOVELTY - The sensor has a hydrogen-chromic pigment core comprising a platinum group metal oxide partially attached to a surface of a porous support. A polymer film is dispersed with the pigment core. The porous support is selected from zeolite, metal-organic structure (MOF), carbon body, graphite, graphene, carbon nanotube, porous silica, porous polymer, clay and porous titania. The polymer film comprises a styrenic block copolymer, polyurethane, polyvinylidene fluoride (PDF), polyethylene terephthalate (PET) and a porous material selected from a group consisting of cellulose, PVC and PVC. USE - Hydrogen sensor based on porous material e.g. zeolite, metal-organic structure (MOF) and porous support. ADVANTAGE - The hydrogen sensor has excellent discoloration rate, elasticity, and can be transformed into various shapes according to the use environment and purpose. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a hydrogen sensor based on porous material.
