Beyond membrane: Efficient water treatment by carbon channel array

1.研究了分散纳米纤维素对单向冷冻法制备的多孔纤维素整体材料的结构、力学性能和传质性能的影响。结果表明，纳米纤维素的长径比和浓度都影响其形成连通孔壁的可能性。此外，纵横比影响纳米纤维素重排的均匀性。因此，得到了具有不同结构的多孔纤维素整体材料，包括不规则蜂窝状、排列良好的蜂窝状和不规则层状微通道.以纳米纤维素为结构导向剂，炭黑/酚醛树脂为碳源，采用单向冷冻法制备了韧性炭微蜂窝。

1. We investigated the effects of dispersed nanocellulose on the structure, mechanics, and mass transport property of porous cellulose monoliths prepared by unidirectional freezing. The results indicated that both the aspect ratio and concentration of the nanocellulose affect their possibility of forming connected pore walls. Additionally, the aspect ratio affects the uniformity of the nanocellulose rearrangement. Consequently, porous cellulose monoliths with various structures including irregular honeycomb-, well-aligned honeycomb- and irregular lamellar-shaped microchannels are obtained.2. A tough carbon microhoneycomb was synthesized by the unidirectional freezing method with nanocellulose as a structure-directing agent and carbon black/phenol-formaldehyde resin as carbon sources.
