采用1.4MW/mm ~ 2（波长532 nm，脉宽5 ns）的激光烧蚀聚硅氧烷油中的铜片制备了铜纳米颗粒。聚硅氧烷油有助于防止Cu颗粒的氧化和聚集。通过TEM观察制备的样品证实了2- 20 nm的颗粒尺寸。通过室温固化聚硅氧烷制备了含Cu纳米粒子的固体材料。
Cu nanoparticles were fabricated by ablating a Cu plate in polysiloxane oil with laser pulses of 1.4MW/mm2(wavelength: 532nm, pulse width: 5ns). Polysiloxane oil was useful to avoid oxidation and aggregation of Cu particles. Particle size of 2–20nm was confirmed by TEM observation of fabricated samples. Solid materials containing Cu nanoparticles were also fabricated by curing polysiloxane at room temperature.
