We discuss the effect of joule heat which comes from eletroosmosis flow on the microfluidic chip. Our microfluidic chips are fabricated from polymethyl methacrylate (PMMA). As everyone knows, PMMA is a poor conductor of heat, and its transfer coefficient is only 0.19W/m·K in room temperature. So, the heat is generated by eletroosmosis canʼt conduct outside the microchannels of microfluidic chip easily. We research the effect joule heat on walls of microchannels which are made of PMMA. During our study, interior surface of microchannelsʼ hydrophobicity is changed by effect of joule heat.
