    • A method of forming articles having closed microchannels includes the steps of providing a substrate including a composite material, the composite having metal nanoparticles dispersed in a polymer matrix. The substrate is irradiated with a laser beam at an intensity and time sufficient to selectively remove the polymer below a surface of said substrate to form at least one microchannel, wherein the intensity and time is low enough to avoid removing the polymer above the microchannel, wherein an article having at least one closed microchannel is formed. A metal nanoparticle/polymer composite composition can have functionality that can undergo addition reactions to seal or join pieces of polymers or composites upon irradiation of the composition placed on one or more pieces.
    • 形成具有闭合微通道的制品的方法包括提供包括复合材料的基材的步骤,所述复合材料具有分散在聚合物基质中的金属纳米颗粒。 以足够的强度和时间照射激光束的衬底,以便选择性地去除所述衬底的表面下方的聚合物以形成至少一个微通道,其中强度和时间足够低以避免去除微通道上方的聚合物,其中 形成具有至少一个封闭微通道的制品。 金属纳米颗粒/聚合物复合组合物可以具有在放置在一个或多个片上的组合物照射时可以经历加成反应以密封或连接聚合物片或复合材料片的官能团。
