Abstract
A method for manufacturing a PDMS device in accordance with an exemplary embodiment of the present invention surface treats the entire surface of a pattern with a thiol group (—SH), so that a hydrogel may be connected to the surface of the pattern by a covalent bond under ultraviolet rays. Therefore, a PDMS device manufactured by the above method has an advantage in that the shape thereof may be stably maintained without the swelling or desorption of a hydrogel even when an electrolyte is filled in a pattern.
Claims7
A method for manufacturing a PDMS device, the method comprising:
- (a) preparing a first PDMS substrate and a second PDMS substrate at least one of which has a pattern formed thereon;
- (b) introducing a hydroxyl group (—OH) on the surface of the first PDMS substrate and the surface of the second PDMS substrate;
- (c) introducing a first thiol group (—SH) on the surface of the first PDMS substrate, and introducing an epoxide on the surface of the second PDMS substrate;
- (d) bonding the first PDMS substrate and the second PDMS substrate to form a PDMS structure;
- and
- (e) substituting the epoxide present on the surface of the pattern of the PDMS structure with a thiol group.
