Meanwhile, it could be in-situ deposited current collector by electro-polymerization, making binder-free free-standing for Li-S batteries. S/PTBT...
Two-dimensional (2D) covalent fused-ring aromatic frameworks (FAFs) can be regarded as holey graphene and hold considerable potential in many applications. However, the development of such materials has been seriously limited by their poor solubility. In this work, four soluble 2D frameworks, FAF1–FAF4, common organic solvents, were successfully synthesized creating large pore structures attaching long side-chain substituents. They possess high molecular weights (Mw = 56,500–87,000 Da)...
