Tailoring of free standing microchannel structures via microtemplating

Original language description

The preparation of ceramic microchannel structures from powder based material is a time consuming, expensive or in?exible process. This work demonstrates microtemplating ? a new reliable and economical fabrication method for preparing ceramic alumina self-supporting microchannels with diameters from 10 to 1000 mm. The basis for this method is the controlled dip-coating of a sacri?cial polymeric ?ber template with suspensions containing sinterable particles. Subsequent sintering results in self-supporting ceramic microchannels. Thermal behavior of a microtemplate is critical for achieving self-supporting microchannels. We used polyamide, keratin, para-aramide, polypropylene, and polyimide ?bers to set models of microtemplate thermal behavior. We found that the negative in?uence of thermal expansion and gas production could be eliminated by microtemplates with hollow and porous internal structure. Furthermore we show ?exibility of the green stage procedure on an alumina micro?uidic loop
