A facile approach was proposed to synthesize uniform ZnO nanofibril with tunable dimension as a function of the template size by using electrophoretic deposition (EPD) process. A mathematical model describing the interaction and coagulation of ZnO nanoparticles within the anodic alumina membrane (AAM) channel environment during EPD is presented, and the related deposition mechanism, morphology, and dimension of the ZnO nanofibril were also discussed. The result shows that the diameters of the fabricated ZnO nanofibrils are uniform and their values are close to the theoretically predicted values for different AAM channel sizes.
