Formation of a Novel Polypyrrole/Porous Phosphate Glass Ceramic Nanocomposite

Abstract: Este trabalho focaliza a obtenção de um novo nanocompósito, formado mediante a polimerização in situ de monômeros de pirrol na superfície dos poros de vitrocerâmicas porosas com esqueleto LiTi2(PO4)3, após troca-iônica com cobre.This work is concerned with evidences of a new composite system, formed by in situ polimerization of pyrrole moieties in the copper-exchanged pore surface of LiTi2(PO4)3 glass ceramic.

“…Therefore, the gc-LVCP exhibits leachability up to approximately 45 vol.%. In summary, the preliminary data reported here allows us to conclude that fabrication of porous glass-ceramic monoliths with skeleton of V(PO 3 ) 3 and Ca 3 (VO 4 ) 2 and having a three-dimensional network structure using vanadium phosphate glass as precursor, was obtained and is reported here for the first time. The pgc-LVCP can be a promising porous host for ICS the because Ca 3 (VO 4 ) 2 phase has ferroelectric and luminophor properties 19,21 while the V(PO 3 ) 3 phase exhibits magnetic property associated with high degree of mechanical, chemical and thermal stability.…”

“…O desenho de materiais em nanoescala pode contribuir para a otimização e o surgimento de novas propriedades, permitindo o uso desses sistemas em diversas aplicações, como na óptica, eletrô-nica, catálise, biotecnologia e eletroquímica do estado sólido [1][2][3][4][5] . Considerando a importância das interfaces para a eletroquímica, os pesquisadores vêm desenvolvendo novos sistemas à base de nanocompósitos, os quais são caracterizados pelas dimensões das partículas e/ou da distância entre os seus constituintes em uma escala nanométrica 6,7 .…”

“…Considerando esses resultados de MECQ, pode-se deduzir alguns aspectos importantes. Primeiramente, quando o cátodo é constituído de uma mistura de PANI e V 2 O 5 em uma escala nanométrica, ClO 4 -não participa do processo de compensação de cargas do PCE. Os átomos de oxigênio do óxido, com densidade de carga negativa, impedem a intercalação de ânions e compensam a carga positiva da PANI formada durante o processo de oxidação.…”
