The affinity of various amphiphilic solutions in the microchannel was influenced by the polarity ratio and the size of molecules. The polarity ratio of isopropyl alcohol (IPA) was closest to that of the recovered PDMS surface and the chain length of IPA was also suitable for high affinity. IPA showed the highest affinity for the recovered PDMS and was selected as the continuous phase to form oil droplets in a PDMS microchannel. With this new continuous phase solution, IPA, we could successfully generate not only oil droplets but also double emulsions in the PDMS microfluidic chips.
