摘要

Surface pattering engineering techniques are essential to fabricate advanced topographies that can be use to modulate cell and tissue response in bio-materials. Particularly, direct laser interference patterning permits fabrication of repetitive arrays and microstructures by irradiation of the sample surface with coherent beams of light. In this study, we explore the possibilities of this technique to produce advanced architectures on several polymeric substrates. The previously calculated interference patterns using the well known interference theory could be directly reproduced on the polymeric surfaces. Moreover, the cross-section of the structured polymers changes depending on the intensity of the laser beams and number of laser pulses, and photomachinability of polymers is highly influenced by laser wavelength. High absorbance of the polymeric materials at specific wavelengths allows the reduction of the laser intensity required to achieve a determined structure depth. In addition, copolymers of methylmetacrylate-styrene were also studied showing that different types of periodic structures could be obtained depending on laser intensity. The obtained results were compared with thermal simulations by finite element methods as well as classical models.
