Abstract
Disc-like nanoparticles are desirable for fundamental studies of self-assembly, liquid crystal phenomenon, diffusion and rheology behavior. However, the realization of such energetically less favorable nanostructures, especially via facile liquid-phase synthesis chemistry, remains a great challenge. Herein, we report a novel process to synthesize donut-shaped polymer nanodiscs with tunable thickness in aqueous solution, based primarily on the phase-transition of stearic acid and subsequent edge-preferential polymerization of benzoxazine induced by Tween-80. In this process, the spatial distribution difference of Tween-80 on stearic acid crystal between edge and center played a crucial role in the shape evolution, specifically the edge formation of donut-shaped polymer nanodiscs. More importantly, the porous carbon with perfectly inherited morphology could be obtained by a followed pyrolysis. In addition, micron-sized circular, rhombic polymer sheets and nanospheres have also been produced by simply modulating the molar ratio of stearic acid/Tween-80. This research provides a new perspective towards the precise construction of 2D colloidal and porous carbon nanomaterials by means of solution chemistry and, more importantly, adds to great potential for corresponding modeling studies and personalized applications.
