The enhanced poly(?-caprolactone) melts flow behaviors though nanoscale channels under vibration were observed. The effect of vibration on the nanoflow is dependent on the vibration frequency of piezoelectric transducer that generates the vibration fields. The flow rate of poly(?-caprolactone) melts in nanochannels increases with the increase of vibration frequency within the range from 2.0 to 14.0 kHz. The observed enhanced flow through nanochannels under vibration is a new nanoscale phenomenon, which is potential in vibration-assisted nanofluidic, nanoimprint lithography, and micro-/nanoinjection molding etc.
