The sheet resistance (Rs) and transmittance (T) of the PVB/AgNWs films are closely related to the AgNWs density and PVB thickness. Rsand T values at 550 nm were used to calculate the figure of merit (FoM, ΦTC) as defined by the Haacke equation37. $${{\rm{\Phi }}}_{{\rm{TC...
Initially, 3.0 g of graphite powder was introduced into 70.0 mL of concentrated sulfuric acid under stirring to achieve a homogeneous dispersion. Maintaining a temperature below 20 °C, this dispersion was transferred to an ice bath, where 9.0 g of potassium permanganate was carefully added. ...
