这种观点提出了一种最近开发的方法，通过一种新形式的光导向组织的光反应聚合物介质组织聚合物和聚合物复合材料。在合适的条件下，这样的介质将与光相互作用，在相互的动态过程中，这导致输入光场的自发组织，并且重要的是，聚合物介质。新的材料结构可以在自由基引发的介质、聚合物共混物和聚合物-溶剂混合物以及可能更复杂的多组分配方中产生。概述了基本原理和化学现象以及示例性材料结构。使用这种新的加工方法生产的材料可用作功能涂层，纹理表面和膜，以及通过选择聚合物组合物的许多其他应用。关键开放的问题和领域，进一步调查和进步。光图案形成过程的动力学耦合到光反应物质是一个有前途的新方法，组织材料的一系列关键应用，并揭示了有趣的非线性动力学现象的组织材料。
This perspective presents a recently developed approach to organize polymer and polymer composite materials through a new form of light-directed organization of photoreactive polymeric media. Under suitable conditions, such media will interact with light, in a mutual dynamic process, that results in the spontaneous organization of both the input light field and, importantly, the polymer media. New material structures can be created in free-radical-initiated media, polymer blends and polymer-solvent mixtures, as well as possibly more complex, multicomponent formulations. An overview of the underlying principles and chemical phenomena and exemplary material structures are presented. Materials produced using this new processing approach can be used as functional coatings, textured surfaces, and membranes, as well as a host of other applications via selection of polymer composition. Key open questions and areas for further inquiry and advancement are presented. Coupling the dynamics of light pattern formation processes to photoreactive matter is a promising new approach to the organization of materials for a range of critical applications and reveals interesting nonlinear dynamic phenomena in the organization of materials.
