Fabrication of Solvent Resistance Poly(dimethylsiloxane) Microfluidic Devices by surface modification with hybrid material |
| 초록 |
A simple method was established for fabricating solvent-resistant microfluidic devices. Poly(dimetylsiloxane) based microfluidic devices can be modified easily with with HR4, a hybrid inorganic/organic polymer. This modification remarkably increases the resistance of PDMS microfluidic channels to various solvents because it leads to a significant reduction in the rate of solvent absorption and consequent swelling. The compatibility of modified PDMS with a wide range of solvents was investigated by the evaluation of swelling ratios measured by changes of weight in standard blocks. Microfluidic devices based on HR4-modifed PDMS was applied to the formation of water-in-oil (W/O) and oil-in-water (O/W) emulsions. This high compatibility with a variety of solvents can expand the application of microfluidic systems using HR4-modifed PDMS to many research fields. |
