阅读说明：本技术 用于批量生产包括石墨烯的原子级薄的二维材料的装置和方法 (Apparatus and method for mass production of atomically thin two-dimensional materials including graphene ) 是由 保罗·拉迪斯劳斯 李·格拉斯哥 罗兰·马歇尔 于 2017-10-13 设计创作，主要内容包括：本发明提供了一种通过使得块体层状材料如石墨分层来制备石墨烯和类似原子级层状材料的装置；该装置包括：泵(112)以及冲击头(16),泵(112)用于在大于1MPa压力下沿着流体管道(12)泵送流体并且抵靠冲击头(16),该流体是块体层状材料的固体颗粒的悬浮液；冲击头(16)具有与进入流体的轨迹垂直或基本垂直的冲击面并且相对于管道(24)的近端作为主轴,以便形成狭窄且可变化的间隙(20),其中所述冲击头关于与所述主轴对齐一致的纵轴对称,使得该对称允许冲击头的旋转。该装置提供了延长的头部寿命并且避免了在隔离区中灾难性头部磨损。更好地保持整个过程的产品质量。并且可以实现自动解锁的分层装置所带来的益处,同时保持高产品质量和一致性。间隙尺寸相对小的变化足以避免堵塞,例如通过用于分层的高剪切间隙中大颗粒或颗粒组的聚集而发生的堵塞。(The present invention provides an apparatus for preparing graphene and similar atomic scale layered materials by layering bulk layered materials such as graphite; the device includes: a pump (112) and an impact head (16), the pump (112) for pumping a fluid at a pressure greater than 1MPa along the fluid conduit (12) and against the impact head (16), the fluid being a suspension of solid particles of a bulk laminar material; an impact head (16) having an impact face perpendicular or substantially perpendicular to the trajectory of the incoming fluid and acting as a main axis relative to the proximal end of the conduit (24) so as to form a narrow and variable gap (20), wherein the impact head is symmetrical about a longitudinal axis aligned with the main axis such that the symmetry allows rotation of the impact head. The device provides extended head life and avoids catastrophic head wear in the isolation zone. The product quality of the whole process is better maintained. And the benefits of an automatically unlocking layered device can be realized while maintaining high product quality and consistency. A relatively small change in gap size is sufficient to avoid clogging, such as occurs by the aggregation of large particles or groups of particles in the high shear gap used for stratification.)
