Synthesis variables effect on TiO2/polyester fabrics photoactivity and stability
TiO2-SiO2 coatings on fabric samples were obtained by immersion of 9 cm2 of commercial polyester in a TiO2-SiO2 suspension. This suspension was prepared by adding TiO2 P25 to a silica matrix obtained from the hydrolysis of tetraethyl orthosilicate (TEOS). The aim of this work was to study the relati...

| description |
TiO2-SiO2 coatings on fabric samples were obtained by immersion of 9 cm2 of commercial polyester in a TiO2-SiO2 suspension. This suspension was prepared by adding TiO2 P25 to a silica matrix obtained from the hydrolysis of tetraethyl orthosilicate (TEOS). The aim of this work was to study the relationship between the immersion time of the fabric on the photocatalytic activity and stability of the coating against several cycles of use and washing. Obtained samples were characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and infrared spectroscopy (FTIR-ATR). Evaluation of modified fabrics was performed by self-disinfection tests under 250W/m2 of simulated sunlight using E. coli as model bacteria. In general, all modified fabrics (except that obtained at 2h immersion time) inactivated bacteria in less than 120min and its regrowth was prevented for at least 24h after the disinfection tests. It was determined that low immersion time (3-4h) lead to active and stable fabrics to 3 cycles of use and washing, whereas higher immersion times (12h) lead to more active but unstable fabrics. |

Muestras de tela recubiertas con TiO2-SiO2 fueron obtenidas por inmersión de un poliéster comercial de 9 cm2 en una suspensión de TiO2-SiO2.Esta suspensión se preparó adicionando TiO2 P25 a una matriz de sílice sintetizada mediante la hidrólisis de ortosilicato de tetraetilo (TEOS). El objetivo de este trabajo fue estudiar la relación entre el tiempo de inmersión de la tela, y la actividad fotocatalítica y estabilidad del recubrimiento a varios ciclos de uso y lavado. Las muestras obtenidas fueron caracterizadas por microscopía electrónica de barrido (SEM), espectroscopía de energía dispersiva (EDS) y espectroscopía infrarroja (FTIR-ATR). La evaluación de los textiles se llevó a cabo mediante pruebas de autodesinfección bajo 250W/m2 de luz solar simulada usando E. coli como microorganismo modelo. En general, todas las telas modificadas (excepto las obtenidas con 2h de inmersión) inactivaron la bacteria en menos de 120min, previniendo su recrecimiento bacteriano al menos por 24h después de las pruebas de desinfección. Se determinó que los tiempos de inmersión bajos (3-4h) dejan telas activas y estables a 3 ciclos de uso y lavado, mientras que tiempos de inmersión más altos (12h) dejan telas más activas pero inestables.Amostras de tecido revestidas com TiO2-SiO2 foram obtidos por imersão de um poliéster comercial de 9 cm2 em uma suspensão de TiO2-SiO2. Esta suspensão foi preparada por adição de TiO2 P25 a uma matriz de sílica sintetizado por hidrólise de ortossilicato de tetraetilo (TEOS). O objetivo deste trabalho foi estudar a relação entre o tempo de imersão do tecido, e a atividade fotocatalítica e a estabilidade do revestimento a vários ciclos de utilização e de lavagem. As amostras obtidas foram caracterizadas por microscopia eletrônica de varredura (MEV), espectroscopia por dispersão de energia (EDS) e espectroscopia no infravermelho (FTIR-ATR). A avaliação dos tecidos foi realizada por meio de testes de autodesinfección sob a luz solar simulada a utilização de E. coli como um modelo microrganismo. Em geral, todos os tecidos modificados (exceto aqueles obtidos com 2h de imersão) inativar bactérias dentro de 120min de irradiação, impedindo o seu novo crescimento bacteriano de pelo menos 24h após o teste de desinfecção. Encontrado que com tempos de imersão de baixo (3-4h) são obtidos tecidos ativos e estáveis a 3 ciclos de utilização e de lavagem, enquanto que os tempos de imersão mais elevado (12h) são obtidos tecidos mais ativos mais instáveis.application/pdfengUniversidad Industrial de Santanderhttps://revistas.uis.edu.co/index.php/revistaion/article/view/5984/6473Revista ION; Vol. 29 Núm. 2 (2016): Revista IONRevista ION; Vol. 29 No. 2 (2016): Revista IONREVISTA ION; v. 29 n. 2 (2016): Revista ION2145-84800120-100XCoated FabricTiO2-SiO2PhotocatalysisE.
