▎ 摘　　要

NOVELTY - Composition comprises graphene dispersion, polymethylsilsesquioxane resin and a polyethylene resin-containing solution. USE - The composition is useful for detecting alkaline leakage using leak detection sensor (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for leak detection sensor comprising a base film layer and a leak sensing layer including a sensing line formed on the base film layer and a conductive line spaced apart from the sensing line by a predetermined distance, where the sensing line is formed from the composition.
