HYDROPHILIC TREATMENT OF A CARBON FIBER CONSTRUCTION
A method is provided for making a hydrophilic carbon fiber construction comprising the steps of: a) immersing a carbon fiber construction in an aqueous dispersion of one or more metal oxides, comprising: i) 1-15 % by weight metal oxide; ii) 0.01 %-5 % by weight dispersant; and b) subsequently heatin...

Zusammenfassung: | A method is provided for making a hydrophilic carbon fiber construction comprising the steps of: a) immersing a carbon fiber construction in an aqueous dispersion of one or more metal oxides, comprising: i) 1-15 % by weight metal oxide; ii) 0.01 %-5 % by weight dispersant; and b) subsequently heating the carbon fiber construction sufficiently to remove substantially a ll of the dispersant. Typically the entire method can be completed in less than 20 minutes. In addition, a hydrophilic carbon fiber construction made according to the method of the present invention is provided, typically havi ng a loading of metal oxide equivalent to 20-50 mg metal per gram of carbon. |
