초음파와 니들펀칭 공정을 이용한 소수성 ITO 나노입자의 PET 직물 담지

초록

Incorporation of long-chain capped nanoparticles on polyester textiles such as polyethylene terephthalate (PET) is challenging due to the low surface energy and chemical inertness of PET. We present a binder-free, ultrasonication method to immobilize indium tin oxide (ITO) nanoparticles on PET textiles while preserving the native fiber structure. Oleic acid-capped colloidal ITO nanoparticles were successfully incorporated to the PET textiles at 40 °C, which is confirmed by X-ray diffraction (XRD). The nanoparticle-incorporated PET textiles are shows high stability in washing condition even in the presence of detergent. The plasmonic property of ITO nanoparticles endows photothermal effect. Under a xenon solar simulator, ITO-loaded textiles exhibited high heating rates. This simple process enables durable, NIR-responsive PET textiles without plasma treatment or polymer binders.
