Abstract

"MéTODO PARA PREPARAR UMA DISPERSãO ESTáVEL DE NANOPARTìCULAS DE CARBONO EM UM LìQUIDO". A introdução de nanotubos em um líquidos provê um meio para mudar as propriedades físicas e/ou químicas do líquido. Melhorias em transferência térmica, propriedades elétricas, viscosidade e lubricidade podem ser realizadas mediante a dispersão de nanotubos em líquidos; entretanto, nanotubos comportam-se como partículas hidrofóbicas e tendem a se aglomerar juntos em líquidos. Métodos para preparar dispersões estáveis de nanotubos são descritos e tensoativos/dispersantes são identificados os quais podem dispersar nanotubos de carbono em meio líquido aquoso e de petróleo. O dispersante apropriado é escolhido para o nanotubo de carbono e o meio baseado em água ou óleo e o dispersante é dissolvido no meio líquido para formar uma solução. O nanotubo de carbono é adicionado à solução contendo dispersante com agitação, ultrassonificação e/ou combinação destas.
