Abstract

GOMEZ, L. M. et al. Effect of energy in the size of pyrrole-derived particles synthesized by plasma. Superf. vacío [online]. 2012, vol.25, n.2, pp. 88-91. ISSN 1665-3521.

This work presents a study about the synthesis by plasma of particles obtained from pyrrole with the purpose of evaluating the influence of the energy applied to the synthesis on the size and morphology of particles. The syntheses were performed with resistive glow discharges at 13.56 MHz, 10-1 mbar and 40-120 W. The particles have spherical morphology with mean diameter between 109 and 205 nm decreasing linearly with the energy of discharges. The structure of particles preserved great part of the aromatic functionality of pyrrole combined with C=O and C=N chemical groups that may help in the biocompatibility of the material.

Keywords : Particles; Pyrrole; Energy; Plasma.
