“…The application of microreactors is expected to have a number of advantages like high heat and mass transfer rate reactions as well as excellent thermal and chemical resistance. Thus, the reaction can be performed under more aggressive conditions with higher yields than it can be achieved with conventional reactors [1][2][3][4].…”

The aim of the work was to develop a sacrificial paste suitable for securing channels during shaping of ceramic materials with internal structures via combination of tape casting and soft lithography. Poly(ethylene glycol) methyl ether and polyethylene glycols with different molecular weight were selected as a main components of a sacrificial paste due to their compatibility to UV curable dispersion. The research shows that sacrificial paste should be characterized by proper melting point. This goal was achieved by using a composition of PEG600 with 15wt.%PEG20000 and 10wt.% carbon. The invented sacrificial paste solidify beyond 27ºC (melting point). after heating up to 80ºC the viscosity of paste is low enough and easily fills the channels with diameter of 150-300µm. What is more, the operational time during free cooling from 80ºC to solidification is around 8 minutes what gives enough time for application. Carbon was added as a modifier of rheological properties and as a black dye that helps in visual evaluation of a degree of filling channel. The first test proved that proposed method of preparation of ceramic samples with application of invented sacrificial paste is reliable and can be practically applied.

“…Another used sacrificial layer has been a strontium carbonate (SrCO 3 ) in an epoxytype ink which is dissolved by immersing the structure in a weak acidic solution [11,12]. Nathalie Serra et al [6,13] employed a solution based on trimethylolethane removed by thermal treatment to develop bridges and cantilevers by screen printing. Another sacrificial layer used to manufacture bridges by inkjet printing was a commercial photoresist Microposit ® 1813 ® from Shipley [14].…”

“…Wei et al [17][18][19][20][21] fabricated piezoelectric cantilevers on cotton by screen printing. Alumina substrate has been chosen to manufacture suspended structures for several authors [6,12,13,[22][23][24]. A few examples can also be found using plastic surfaces: a microelectromechamical switch developed on polyimide substrate by lamination techniques [25,26], switches on Kapton polyimide [15], electrostatic microactuators made of a flexible sheet [27], or printed bridges on polyethylene terephthalate (PET) [14] or a cantilever also developed on PET by screen printing [28].…”

“…Various original and characteristic micro-fluidic devices are proposed and fabricated for researches, and investigated in detail (Jacobs, et al, 2009) (Serra, et al, 2011) (Bouhadda, et al, 2012) (Curto, et al, 2012) (Kashkary, et al, 2012). However, on the final practical stage, the devices are generally thrown away after once used.…”

Fabrication of Precise Micro-fluidic Devices using a Low-cost and Simple Contact-exposure Tool for Lithography

Various methods have been proposed for fabricating biochemical, pharmaceutical, and medical microfluidic devices. Among them, the new method using groove patterns formed in a thick resist film as the flow paths is promising. Because the flow paths are directly fabricated only using one lithography process, complicated flow paths can be obtained easily and precisely. However, it is often required to prepare an expensive exposure system newly for applying the method to practical fabrications of the devices. For this reason, the effective method has not been sufficiently utilized practically. Here, a very low-cost exposure tool was developed to make a breakthrough. In the new tool, functions were minimized, and limited to indispensable ones. However, because the required pattern widths were in the range of 50-200 μm, flowpath patterns were nicely fabricated. Assembling the fabricated micro-mixer chips with the vessels and lids, it was verified that two liquids were simultaneously injected into the mixer paths without leaks. Thus, it was clarified that the new exposure tool was useful. Micro-patterns fabricated using the new simple exposure tool will be useful for developing various micro-fluidic devices.
