Durable, Lightweight, Washable and Comfortable Cooling Textiles from Nanodiamond/Polydopamine/Wool Nanocomposites

The development of cooling textiles has a significant impact on energy saving and cost-effectiveness in the context global warming. Engineering with performance while maintaining their intrinsic traits, for example, lightweight, washable, comfort, durability, is great challenge developing personal garments. Here, synthesis nanodiamond/polydopamine/wool (ND-PDA-wool) nanocomposites through facile dip-coating approach demonstrated. Different types ND including detonation (DND), carboxylated (ND-COOH) hydroxylated (ND-OH), are used, dopamine templating applied to achieve strong adhesion bonding between fiber ND. morphology, structure, properties as-coated fabrics characterized, together comfort measured. Due excellent thermal conductivity ND, temperature difference coated uncoated ones around 2.4–3.9 °C within short time span 30 min. ND-PDA-Wool demonstrated enhanced stability improved mechanical water absorbency greatly well-maintained air permeability. ND-PDA-wool composite offer strategy develop durable, comfortable immense potential reducing space costs.
