PROJECT TITLE: New Material: Hollow Fibers
PROJECT DESCRIPTION: New Material: Hollow Fibers Various Substances can be Introduced through the Micropores to Alter the Properties of the Fibers Laser irradiation on synthetic fibers may produce a ripple-like pattern on the originally smooth surface. Laser irradiation on hollow fibers of the same materials can result in the formation of micropores along the ripple-patterned surface. The size and density of these micropores can be controlled by a pre-designed scheme of laser dosage. We have successfully produced micorpores of diameters in the order of a micron on a polyethylene terephthalate (PET) fiber with external diameter of 25 microns and bore diameter of 12 microns.
