Membranas de PVA e sílica para aplicação em célula a combustível de alimentação direta de álcool

Liz Contino Vianna de Aguiar, +2 more
- 01 Dec 2014 - 
TL;DR: In this article, PVA/silica membranes were synthesized by the sol-gel process under acidic conditions and Tetraethoxysilane (TEOS) was used as precursor with concentration between 5 and 30% in two distinct systems.
