Abstract

Maskless femtosecond laser two-photon polymerization micromachining technology is capable of inducing triggered two-photon polymerization (2PP) to fabricate three-dimensional additive templates with structural linewidths capable of exceeding the optical diffraction limit. With the help of polymer templates, disordered structural unit nanoparticles are spontaneously assembled into ordered structures through element-to-element interactions driven by free-energy minimization. In this paper, quadrilateral and hexagonal patterned tiling polymer templates were successfully fabricated by designing and tuning the processing parameters. The nanoparticle of appropriate size arrangement corresponding to the template pattern is expected to be successful in obtaining it by directed self-assembly. At the same time, the near-field and far-field optical properties of the template area under different assembly schemes were simulated and analyzed by CST Studio Suite based on finite element analysis.
