Process for producing microcapillaries on plastic surface.

摘要

A process for producing micro-capillaries on a plastic surface comprises directing a pulsed laser radiation beam onto a focal area of the plastic surface. The beam comprises photons having an energy greater than about 3.5 eV, possesses a fluence in the range of from about 400 to about 1500 mJ/cm<-><2> and is pulsed at a frequency of from about 50 to about 100 Hz. The plastic surface and the radiation beam are translated relative to one another in a manner whereby the focal area is exposed to from about 100 to about 200 pulses of the beam for a temporal pulse duration of from about 10 to about 40 nsec.
