    • A metal nanoparticle supported on or dispersed in a polymer is irradiated with photons from a laser source to address the nanoparticles. The polymer is transmissive to the photons and addressed nanoparticles transform the energy of the photon to heat which is transferred to a material in the vicinity of the nanoparticle. The locally heated material undergoes a physical or chemical transformation upon heating. The transformed material can be a material in the proximity of the metal nanoparticle supported polymer or metal nanoparticle/polymer composite. In this manner thermally induced physical or chemical transformations can be carried out in very small volumes of material without significant heating to the bulk of the material.
    • 负载在或分散在聚合物中的金属纳米颗粒用来自激光源的光子照射以解决纳米颗粒。 聚合物对光子是透射的,并且所寻址的纳米粒子将光子的能量转化为热,其转移到纳米颗粒附近的材料。 局部加热的材料在加热时经历物理或化学转化。 转化的材料可以是金属纳米颗粒负载的聚合物或金属纳米颗粒/聚合物复合材料附近的材料。 以这种方式,热诱导的物理或化学转化可以在非常小体积的材料中进行,而不显着加热到大部分材料。

    • 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面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。
