Few‐layer porous graphene is a promising material for a variety of fields. However, the synthesis of few‐layer porous graphene is a great challenge. Here we report a feasible green path to produce few‐layer porous graphene, which was exfoliated from high‐pressure graphite balls onto microspheres with rough surfaces by a mild rolling transfer process. Ordinary ball milling equipment was adopted for the low‐speed (100 rpm) ball–microsphere rolling transfer process. The rolling time (<10 min) was controlled to obtain porous graphene instead of graphene. The porous graphene on the exfoliating microspheres was then easily dispersed in solution by bath sonication. The product contains very few impure functional groups. The hole size and layer distribution of the few‐layer porous graphene have been demonstrated to be 2.37±1.17 nm and 2.4±0.7 layers, respectively, and can be adjusted by redesigning the surface of the microspheres.

短滚动转移法软机械法制备几层多孔石墨烯

几层多孔石墨烯是用于各种领域的有前途的材料。然而，几层多孔石墨烯的合成是一个巨大的挑战。在这里，我们报告了一条生产几层多孔石墨烯的可行的绿色路线，该路线通过温和的滚动转移过程从高压石墨球剥落到表面粗糙的微球上。低速（100 rpm）球-微球滚动转移过程采用了普通球磨设备。控制轧制时间（<10分钟）以获得多孔石墨烯代替石墨烯。然后，通过浴超声处理，使脱落的微球上的多孔石墨烯易于分散在溶液中。该产品几乎没有不纯的官能团。几层多孔石墨烯的孔尺寸和层分布已证明是2.37±1.17 nm和2.4±0.7层，
