Due to two-dimensional lattice and unique electrical properties graphene is a material of interest in gas-sensing applications. In contrast to theoretical structure, real-life graphene contains numerous defects that modify its properties. The aim of the following study was to compare the influence of five different gaseous atmospheres and UV radiation on the electrical resistance of metallurgical graphene (HSMG®). Samples of virgin graphene and graphene annealed after transfer were used. Among the tested gases, hydrogen atmosphere showed the biggest impact on graphene resistance. The annealing step meant to cleanse graphene from process residues resulted in decreased graphene susceptibility to UV radiation.

由于二维晶格和独特的电性能，石墨烯是气体传感应用中的重要材料。与理论结构相反，现实生活中的石墨烯包含许多会改变其性能的缺陷。以下研究的目的是比较五种不同的气体气氛和紫外线辐射对冶金石墨烯（HSMG®）电阻的影响。使用在转移后退火的原始石墨烯和石墨烯的样品。在测试的气体中，氢气气氛对石墨烯的电阻影响最大。旨在从工艺残留物中清除石墨烯的退火步骤导致石墨烯对UV辐射的敏感性降低。
