Abstract

"COMPóSITO POLIMéRICO DE NANOTUBOS, MATERIAL COMPóSITO CERáMICO, ELETRODO DE CéLULA DE COMBUSTìVEL, MATERIAL DE EMISSãO DE CAMPO, DISPOSITIVO DE EMISSãO DE CAMPO, E, COMPóSITO CERáMICO DE NANOTUBOS DE CARBONO". Compósitos de nanotubos de carbono de parede única (SWMTs) e um suporte cerâmico (por exemplo, sílica) compreendendo uma pequena quantidade de metal catalítico, por exemplo cobalto e molibdênio, são descritos. A partícula compreendendo o metal e o suporte cerâmico é usada como o catalisador para a produção dos nanotubos de carbono de parede única. O compósito cerâmico de nanotubos assim produzido pode ser usado 'como preparado' sem purificação adicional, proporcionando vantagens de custos significativas. O compósito cerâmico de nanotubos também tem sido apresentado como tendo propriedades melhoradas versus aquelas de nanotubos de carbono purificados em certas aplicações como dispositivos de emissão de campo. O uso de sílicas precipitadas e defumadas tem resultado em compósitos cerâmicos de nanotubos, os quais podem sinergicamente melhorar as propriedades tanto da cerâmica (por exemplo, sílica) quanto dos nanotubos de carbono de parede única. A adição destes compósitos aos polímeros pode melhorar suas propriedades. Estas propriedades incluem a condutividade térmica, a estabilidade térmica (tolerância à degradação), condutividade elétrica, modificação da cinética de cristalização, resistência, módulo de elasticidade, resistência à fratura, e outras propriedades mecânicas. Outros compósitos cerâmicos de nanotabos podem ser produzidos com base em AL~ 2~O~ 3~, MgO e ZrO~ 2~, por exemplo, os quais são adequados para uma grande variedade de aplicações."NANOTUBE POLYMERIC COMPOSITE, CERAMIC COMPOSITE MATERIAL, FUEL CELL ELECTRODE, FIELD EMISSION MATERIAL, AND FIELD NANOTUBE CERAMIC COMPOSITE". Single wall carbon nanotube composites (SWMTs) and a ceramic support (eg silica) comprising a small amount of catalytic metal, eg cobalt and molybdenum, are described. The particle comprising the metal and ceramic support is used as the catalyst for the production of single wall carbon nanotubes. The nanotube ceramic composite thus produced can be used 'as prepared' without further purification, providing significant cost advantages. The ceramic nanotube composite has also been shown to have improved properties versus those of purified carbon nanotubes in certain applications as field emission devices. The use of precipitated and smoked silicas has resulted in ceramic nanotube composites, which can synergistically improve the properties of both ceramic (eg silica) and single wall carbon nanotubes. Adding these composites to polymers can improve their properties. These properties include thermal conductivity, thermal stability (degradation tolerance), electrical conductivity, modification of crystallization kinetics, strength, modulus of elasticity, fracture resistance, and other mechanical properties. Other nanotable ceramic composites may be produced based on AL ~ 2 ~ O ~ 3 ~, MgO and ZrO ~ 2 ~, which are suitable for a wide variety of applications.
