2023年12月21日 · Based on previously developed aqueous COF colloid, we have formulated a stable aqueous COF-based ink that can be successfully printed with a microfluidic-based printing head. Through this system, we achieved precise control over the ink's gelation process, enabling a layer-by-layer printing of pure COF monoliths with arbitrary shapes.

2023年6月8日 · With molecularly well-defined and tailorable 2D structures, covalent organic frameworks (COFs) have emerged as leading material candidates for chemical sensing, storage, separation, and catalysis. In these contexts, the ability to directly and deterministically print COFs into arbitrary geometries will enable rapid optimization and deployment.

2023年12月14日 · This work presents a comprehensive methodology for the transformation of a COF into three-dimensional (3D) scaffolds using the technique of 3D printing. As part of the 3D printing process, a composite material called CelloCOF was created by combining cellulose nanofibrils (CNF), sodium alginate, and COF materials (i.e., COF-1 and COF-2).

2021年1月1日 · Herein, we report a binder-free, 3D printing process for COF materials (SNW-1 and ATFG-COF), capable of producing free-standing, crack-free 3D COF monoliths by the control of the solvent choices and their diffusion and evaporation among the …

Considering the useful applications of 3D printed MOF/COF-based materials, this review will focus on and highlight the successful uses of 3D printed COF- and MOF-based materials in remediation, gas separation, biomedical, and electronic fields.

2019年3月26日 · In this work, we report a general method to integrate COFs with imine or β-ketoenamine linkages into three-dimensional (3D)-printing materials. A 3D-printing template, Pluronic F127, was introduced to coassemble with imine polymers in an aqueous environment.

2024年3月21日 · Recent advances in design strategies regarding both the paste/scaffold formation and the 3D-printing/covering process for preserving the better structural features of M/COFs (surface area, porosity, and micromorphology) in their 3D printed monolith are overviewed and discussed.

共价有机骨架 （cof）是一类多孔共价材料，目前合成的cof通常是不可加工的结晶粉末，这严重影响了了这类材料将来在分子存储、分离、催化和储能等实际应用中的潜力。近些年来，人们通过加入添加剂和粘合剂已经成功对金属有机骨架（mof）进行3d打印，但cof ...

sensing performance of the COFs. In particular, the printed COF-CNT nanocomposite films show high in-plane COF crystallinity and exhibit tunable electrical conductivity as a function of CNT loading, COF pore size, and temperature, ultimately resulting in …

2023年12月21日 · This study presents a novel strategy to address this issue by developing a 3D printable ink comprising a colloidal water suspension of COF nanoparticles. A microfluidic device is engineered that...
