金刚石传统上被认为是世界上最坚硬的材料,复旦大学梅永丰教授课题组通过超薄化和纳米化,降低了金刚石薄膜的抗弯折性能,提高其柔性;并通过应力控制实现三维微结构的自卷曲,实现了微米卷、微米弹簧和卷中卷等结构。同时,完整的三维卷曲管状结构可实现光学模式的谐振,并且由于金刚石具有非常好的热导性能,该卷曲金刚石管状光学 Diamond has traditionally been considered the hardest material in the world. Prof. Mei-Feng Fudan, Fudan University, through the ultrathinization and nanocrystallization, reduced the bending resistance of diamond films and increased their flexibility. Three-dimensional micro-control The structure of the self-crimping, to achieve the micron coil, the coil and other volumes in the spring roll structure. At the same time, a complete three-dimensional crimped tubular structure enables optical mode resonance and because of the very good thermal conductivity of diamond, the crimped diamond tubular optical
