光响应聚合物驱动的表面微结构,作为可动态重构的智能微纳结构体系,凭借其非接触式调控、可大面积扩展制备等优势,成为微纳加工领域的研究热点. 本综述系统梳理了该领域的研究进展,并对2类核心表面微结构形成机理进行了阐明与比较;一是马兰戈尼流主导的流体质量迁移机理,由表面张力梯度驱动聚合物链定向流动,实现纳米级高精度图案复刻,进而揭示了表面张力、掩膜周期、自由体积与溶剂介导策略对微结构的多维度调控规律;二是模量差(梯度交联)的固体力学失稳机理,通过构建局部模量失配,驱动应力释放诱导力学屈曲,进行微米级大形变与复杂有序表面微结构的制备. 在此基础上进一步总结了上述体系在光学加密、柔性电子领域的前沿应用,最后对现存的精度瓶颈、多刺激协同调控等问题进行了展望.
Surface microstructures driven by photoresponsive polymers
as dynamically reconfigurable intelligent micro/nanostructured systems
have emerged as a prominent research hotspot in the field of micro/nanomanufacturing
benefiting from their unique advantages including noncontact manipulation
large-area scalable fabrication and high spatiotemporal resolution. This review systematically summarizes the recent research advances in this thriving field and elaborates as well as systematically compares two core formation mechanisms of surface microstructures. The first is the fluid mass transport mechanism dominated by Marangoni flow
where surface tension gradients drive the directional migration of polymer chains to achieve nanoscale high-fidelity pattern replication. The multidimensional regulation laws of microstructures governed by key factors including surface tension
photomask periodicity
free volume and solvent-mediated strategies are comprehensively revealed. The second refers to the solid mechanical instability mechanism originating from modulus mismatch (gradient crosslinking). By constructing localized modulus mismatch in polymer films
stress relaxation is triggered to induce mechanical buckling
enabling the facile fabrication of microscale large-deformation and complex ordered surface microstructures. On this basis
the state-of-the-art applications of such photoresponsive surface microstructure systems in cutting-edge fields including optical encryption
flexible electronics are further recapitulated. Finally
the existing challenges such as precision bottlenecks and multi-stimulus synergistic regulation are prospected
offering valuable insights for the future development of this promising research area.
