Abstract
Poly(DNTD,N,N′-di[p-phenylamino(phenyl)]-1,4,5,8-naphthalene tetracarboxylic diimide) and its nanocomposite film incorporated with WO3 nanoparticles was prepared by a facile electropolymerization method on an indium in oxide (ITO) coated glass slide from the DNTD monomer and WO3 nanoparticles suspended methylene chloride solution. The morphology and microstructure of the nanocomposite film were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The SEM image shows that the WO3 nanoparticles are uniformly embedded in the polymeric matrix. The nanocomposite film also displays smooth topography with evenly sized and uniformly distributed nanoparticles under high resolution AFM observations. An air-stable electrochromical window was assembled and obtained by a homemade electrochemical cell to study the electrochromism and stability of the nanocomposite film. The composite film exhibits multiple colors at both the cathodic and anodic potentials, i.e., light blue at −1.4 V, o...
