Molecular weaving makes polymer composites stronger without compromising function

Chemistry is a lot like working with building blocks at its most basic level, but the materials are atoms and molecules. COFs – or covalent organic frameworks, a new class of porous crystals – are a great example of a material that behaves like a molecular Lego set, where individual building blocks are connected through strong chemical bonds to form a highly open and structured network. This intricate structure provides a scaffold for polymer chains to thread or wrap during their formation and strength. Think of a woven scarf or basket – a single piece of yarn or twine may not be much on its own, but when woven together, the pattern enhances the final product’s overall performance. Furthermore, when these chains weave together, sometimes even the chemical reactions further strengthen the material’s properties.
