According to CHEN Yonghsheng of Nankai University, graphene can be driven by light sources such as sunlight, and the thrust generated in vacuum conditions is 1,000 times higher than that of polyimide film, studied by Western researchers for “solar sails”. Graphene is among the strongest and thinnest known materials, and can withstand temperatures over 800 degrees centigrade.
