▎ 摘　　要

NOVELTY - A graphene-polymer microfilament array gas sensor comprises a graphene microwire array which is one-dimensional and parallel to each other and extends in a one-dimensional distribution, and polymer film layer on the microwire array. USE - Graphene-polymer microfilament array gas sensor for monitoring food and air pollutant. ADVANTAGE - The gas sensor has high detection efficiency, sensitivity, selectivity, performance stability and excellent processing performance, and can be prepared in simple, easy and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene-polymer microfilament array gas sensor.
