20120085695 | Carbon nanotube wetlaid depth media - Disclosed is a media (such as a filter media) having one or more carbon nanotube (CNT)-containing layer. Each CNT-containing layer contains high temperature refractory fibers (e.g., staple quartz fibers and/or ceramic refractory fibers) that have melting temperatures greater than about 600° C. and in situ grown CNTs. Substantially all of the in situ grown CNTs have one end thereof associated with the fibers. This results in substantially all of the in situ grown CNTs extending away from substantially all of the fibers. Moreover, substantially all of the in situ grown CNTs are dispersed throughout the fibers. In one embodiment the media also includes one or more supporting layer. Each supporting layer contains high temperature refractory fibers that have melting temperatures greater than about 600° C., optionally bulk refractory fibers, optionally E-glass fibers, and optionally microglass fibers. The media can be tailored as a filter media to remove different size particles and have different dirt loading capacities depending upon the desire of the consumer. | 04-12-2012 |
