    Influence of process parameters on the preparation

    Electrostatic powder deposition (ESPD) has been developed as a solvent-free method to prepare pharmaceutical films. The aim of this work was to investigate the influence of process parameters during (1) electrostatic powder deposition, (2) curing, and (3) removal of the film from the substrate on the properties of the film.

    Electrostatic Deposition - an overview

    Electrostatic deposition of AEROXIDE ® powder has been positively tested as one of several techniques used to apply a powder onto the surface of a film during blow molding. Further, it is proposed to use a rollerhead extrader to press the particles into the surface of the plastic film while this is still soft enough to be partially penetrated

    The samples were prepared in the pure state by ultrasonic spray, and elaborated deposition was completed via electrostatic adsorption. Scanning electron microscopy, X-ray powder diffraction, and atomic force microscopy were used to characterize the size of the particles; this was subsequently followed by differential scanning calorimetry.
