Abstract
In this study, Antimony-doped tin oxide (ATO) fixed and loaded on one-dimensional halloysite nanotubes (HNTs) were fabricated using the co-precipitation method to improve photocatalytic efficiency and dispersion of ATO. After that well dispersed ATO@HNTs nanofiller (AH) modified by monoethanolamine (mAH) was also embedded in the polyvinylidene fluoride (PVDF) coating by solution blend to further broaden the application fields. The results showed the introduction of HNTs accelerates electron transfer and promotes the decomposition of rhodamine B (Rh B). More significantly, with the effect of the well-dispersed mAH nanofillers, PVDF coating containing 15% mAH degraded more than 90% of Rh B under ultraviolet (UV) irradiation for 2 h, which was 1.2 times higher than that of PVDF coating. In addition, the PVDF/mAH-15% coating exhibits excellent antistatic stability under the harsh conditions of photoaging and thermal aging. Moreover, by comparing temperature differences, the thermal insulation performance of PVDF/mAH-15 coating with 70.24% visible light transmittance is significantly improved by reducing heat conduction and radiation at the same time.
