A novel wicking material using nanostructured titania grown on high aspect ratio titanium micropillars is demonstrated. High aspect ratio titanium micropillars were micromachined from bulk titanium sheets. Nanostructured titania was then grown on the surface of titanium micropillars by oxidation in aqueous hydrogen peroxide solution followed by thermal annealing. The nanostructured titania formed has an open porous structure with a nanoscale pore diameter and wall thickness. X-ray diffraction and pole figure studies indicate the formation of anatase phase of titania and the absence of a preferred orientation in the porous film. The hybrid nanostructured titania on titanium micropillars has excellent hydrophilic properties with a water capillary speed comparable to or exceeding that of conventional wick materials commonly used in heat pipes for the thermal management of electronic devices.
