Cotton fabrics with the main constituent of cellulose, which is hydrophilic, bacterial infected, and flammable, are in urgent need functionalization as a kind widely applied material. To address these issues, this work, modified polyelectrolyte complex (MPEC) coatings polyethylenimine (PEI), polyphosphate (APP), perfluorodecyltrichlorosilane PEI (PFTS-PEI) prepared to construct multi-functionally gradient MPEC on cotton fabrics. Stability synergistic effects hydrophobicity, antibacterial activity, flame retardancy system have been studied. Notably, PFTS-PEI fluorine silicone elements confirmed provide hydrophobicity durability for coatings, not only has no negative effect other functions but also makes some improvement activity. This MPEC-treated fabric finally an rate against S. aureus E. coli 99.9% 96.9%, limiting oxygen index 28.5% water contact angle 118°, can be almost maintained after 20 times washing. The PEC will efficient strategy achieve durable multi-functions cellulose-based

In Situ Assembly of Nanostructured Polyelectrolyte Coatings by Aqueous Phase Separation toward Outstanding Thermal Insulation and Fire Resistance

ACS Materials Letters, Год журнала: 2024, Номер unknown, С. 5418 - 5428

Flame-retardant surface treatments effectively reduce the fire hazard of polymeric foams but are plagued by high coating thickness and deterioration inherent thermal insulation. Constructing a nanostructure can significantly enhance insulation coatings, current methods usually rely on toxic solvents harsh conditions. Herein, we present facile eco-friendly strategy employing Cu2+-assisted aqueous phase separation (APS) for assembly nanostructured polyelectrolyte coatings in situ. Exploiting multiple cross-linking interactions between Cu2+ complex (PEC), unique nanosheet (∼200 nm) structure was assembled PEC coating. When coated rigid polyurethane foam (RPUF), conductivity reduced to 28.1 from 30.0 mW/m·K. Moreover, RPUF manifests limiting oxygen index 36% reduces heat/smoke release (>60%). This work provides cast flame-retardant materials with excellent integrated performances.
