摘要：The multifunctional polyethylene terephthalate (PET) fabrics with flame retardant, antibacterial and super-hydrophobic properties were successfully fabricated by a simple coating approach to enhance the properties of PET fabrics and to make them extensively applicable in a number of fields. The composite coating was composed of ammonium polyphosphate (APP), polydopamine (PDA), PDMS-silica (PDMS-SiO2), and silver nanoparticles (AgNPs). ATR-FTIR spectra, XPS analysis, and SEM-EDS spectrometer were employed to investigate the morphological properties and constitution of these coatings. The flame retardant performance of the multifunctional PET fabrics was determined by LOI, vertical flame test (VFT) and cone calorimeter test (CCT). The results revealed that the APP@SiO2-PDA@Ag PET fabrics' LOI value reached 29.0 %, which was 9.5 % higher than that of pristine PET fabrics. Besides, the APP@SiO2-PDA@Ag PET fabrics could self-extinguish the fire quickly in the VFT. The peak heat release rate and total heat release of the APP@SiO2-PDA@Ag PET fabrics were 34 % and 26 % lower than those of the pristine one. Notably, the multifunctional PET fabrics had excellent antibacterial activity against E. roll and S. aureus. The multifunctional fabrics exhibited super-hydrophobicity with a water contact angle (CA) greater than 150 degrees and showed excellent self-cleaning and antifouling properties. More importantly, the multifunctional PET fabrics still retained excellent flame retardant performance and antibacterial properties after multiple washing cycles.
