Luis Alvarez: 2019 SMEQ Winner

LUIS MANUEL ALVAREZ CERDA

LUIS MANUEL ALVAREZ CERDA received the prize for the best doctorate poster.

The XXXIV National Congress of the Mexican Society of Electrochemistry (SMEQ) and 12th Meeting of the ECS Mexico Section—held this June in Santiago de Querétaro, Mexico—honored Luis Manuel Alvarez Cerda for his work, titled, “Effect of the Polymerization Synthesis Temperature on the Hydrophilic/Hydrophobic Balance in Polyaniline Deposits (PANI) on an Anion Exchange Membrane.”

Each year, SMEQ hosts a poster session which awards prizes by degree (bachelor’s/master’s/doctorate). Alvarez took home the main prize for the best doctorate poster, which includes the opportunity to present at a future ECS biannual meeting.

Abstract

Title: Effect of the Polymerization Synthesis Temperature on the Hydrophilic/ Hydrophobic Balance in Polyaniline Deposits (PANI) on an Anion Exchange Membrane

Coauthors: A. Montes-Rojas and L. M. Torres-Rodríguez

In literature, films of polyaniline (PANi) obtained at low synthesis temperature have had better crystallinity and low electrical resistance. This is why it is interesting to use PANi deposit on exchange membranes at low temperature and evaluate the performance.

In this work, the electrodeposit temperature was 10, 15 and 20 °C using cyclic voltamperometry with 100 cycles. The evaluation was on hydrophobicity, hysteresis, permeability, water content, and crystallinity.

The principal results were that the hydrophobicity and hysteresis increase, but the water content and permeability decrease with the temperature. Finally, the better crystallinity was been obtained at 15 °C.
