Patent

CA 2664837

The present invention generally relates to metal oxide fibers and nanofibers, the processes for making same, and uses thereof. Such metal oxide nanofibers possess the ability to absorb and decompose chemical warfare agents and other toxic chemicals. These nanofibers can be incorporated into protective clothing and devices for breathing or in another example may be used in lithium-ion batteries. In one embodiment, the present invention relates to titania, alumina, and/or magnesia fibers and nanofibers, and to processes for making same. In another instance, alpha-phase aluminum oxide is utilized as one material in nanofibers.

La présente invention concerne d'une manière générale des fibres et nanofibres d'oxyde de métal, des procédés de préparation de celles-ci et leurs utilisations. De telles nanofibres d'oxyde de métal possèdent la capacité d'absorber et de décomposer des agents de guerre chimique et d'autres produits chimiques toxiques. Ces nanofibres peuvent être incorporées dans des vêtements protecteurs et des dispositifs pour respirer ou, dans un autre exemple, peuvent être utilisées dans des batteries à ion lithium. Dans un mode de réalisation, la présente invention concerne des fibres et nanofibres en oxyde de titane, alumine et/ou magnésie, et des procédés de préparation de celles-ci. Dans un autre cas, de l'oxyde d'aluminium en phase alpha est utilisé comme matériau dans les nanofibres.
