The possibilities for the new field of two-dimensional, one-atomic-layer-thick materials, including but not limited to graphene, appear almost limitless. In new research, Penn State material scientist...
加拿大着手石墨烯标准的研究
加拿大 石墨烯标准 研究
2017/4/21
近期，加拿大国家研究理事会(NRC)组建了一个特别研究小组，进行石墨烯标准的研究，这种多功能材料有可能重塑多个产业的格局。石墨烯是迄今人类发现的最薄、强度最大、导电和导热性能最强的材料之一，然而，目前市场销售的石墨烯相关材料的质量差异巨大，尚无用于表征石墨烯的标准，造成对市场提供的大量石墨烯材料无法进行可靠比较，特别是在寻求满足一定目标性能的石墨烯材料时采购风险更大。
