摘要: Filter media are provided having improved conductivity to enhance filtration efficiency and/or dissipate static charge, and methods for making the same. In one exemplary embodiment, the filter media can include a filtration substrate, and at least one conductive coating disposed on at least a portion of the filtration substrate. In use, the conductive coating is coupled to an energy source and it is effective to emit ions when energy is delivered thereto to increase the efficiency of the filtration substrate and/or to dissipate or eliminate static charge generated during filtration.

摘要: 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.
