听,蜘蛛的脚步前不久,在都柏林三一学院的纳米技术实验室里,康纳·柏兰德(Conor Boland)和他的团队为石墨烯找到了新搭档。这个科研团队喜欢把普通家用器具用于实验室研究——2014年,他们发现用厨房中的食品搅拌器快速搅拌石墨,能方便地获得石墨烯。柏兰德从孩子玩的轻黏土中获得灵感,将大约20层原子厚、800纳米长的石墨烯薄片与自制黏土(一种有机硅聚合物)混合,得到了能导电的深灰色混合物G—putty。仅需施加微弱的压力,这种材料的电阻就会发生极大变化。这种特性可以
Listen, Spider’s Footsteps Not long ago, Conor Boland and his team found a new partner for graphene at the Trinity College nanotechnology lab in Dublin. The research team likes to use common household appliances for laboratory research - in 2014, they found graphene was easily obtained by rapidly mixing graphite with a food mixer in the kitchen. Ballanty draws inspiration from the kid’s light clay and mixes about 20 layers of atomic-thick, 800-nanometer-long graphene sheets with a homemade clay, a silicone polymer, to give a conductive, dark gray mixture, G- putty. With only weak pressure applied, the resistance of this material changes dramatically. This feature can be
