STRATIFIED MICROFLUID STRUCTURE, METHOD FOR LAMINATING AT LEAST TWO POLYMER FORMATION ELEMENTS IN ORDER TO FORM STRATIFIED POLYMER MICROFLUID STRUCTURE, AND MANUFACTURING METHOD FOR STRATIFIED POLYMER MICROFLUID STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for sealing a polymer microstructure, which can be simply reproduced and has a high yield.;SOLUTION: In the manufacturing method for a polymer microfluid structure, two or more of structure elements of the microfluid structure are firmly combined with each other, or are laminated with a weak solvent combining agent, especially, acetonitrile and a mixture of acetonitrile and alcohol. The acetonitrile can be used as a weak solvent combining agent in order to seal a microstructure in a non-elastomer polymer such as acetonitrile, polystyrene, polycarbonate, acrylic, or the other linear polymer which forms a three-dimensional microfluid network. The method includes a step of moistening at least one of opposite surfaces of a polymer substrate formation element by the weak solvent combining agent which adjacently comes in contact with opposite surfaces at a designated lower temperature range and activates the combining agent at temperature higher than a low temperature range during a designated period.;COPYRIGHT: (C)2010,JPO&INPIT
