Abstract

In this paper, the light absorption rate with changes in cation and anion of MWCNT ionanofluid was investigated and compared to that of ionic liquid (IL). As a result, the light absorbance of [C12MIM][Tf2N] with a larger cation radius was higher than that of [HMIM][Tf2N]. In addition, the light absorbance of [HMIM][Tf2N] was lower than that of [HMIM][TfO]. When the MWCNT nanoparticles were added to IL, the light absorbance was increased. As the thickness of the fluid layer increased, the solar weighted absorption fraction was also increased; however, the increment of solar weighted absorption fraction in [HMIM][TfO] IL and ionanofluid increased compared to that of [HMIM][Tf2N] and [C12MIM][Tf2N]. Thus, light absorbance increases because molecules interfere with the light transmission as the bonding force increases when the cation is large or the anion is small, and the crystallisation temperature is relatively high.
