Anti-infrared/ultraviolet property of fullerene-containing polyacrylate film

Abstract

High-optical quality polyacrylate films containing a small load of C₆₀ were prepared by blending the soluble polyacrylate with the fullerene C₆₀ derivative poly-[2-(acrylamido)-2-methylpropane sulfonic acid] (PAMPS)-C₆₀. TEM was used to observe the morphological structure of the fullerene-containing polyacrylate solution. The anti-infrared/ultraviolet property was characterised by UV–VIS and FTIR in the wavelength range of 190–5000 nm. Experimental results demonstrated an improved anti-IR/UV property of polyacrylate as well as good diaphaneity. In the visible spectrum, its transmittance was greater than 80%. In the UV region, the transmittance decreased to 10% (<300 nm). Meanwhile, the transmittance was 55·7% in the near IR wave range (4000–14000 cm⁻¹) and 31% in the middle IR wave range (2000–4000 cm⁻¹), respectively. This new nanocomposite material has great potential to serve as an anti-IR/UV thin coating to implement heat insulation in many applications.
