美国纽约罗切斯特大学的研究人员通过用飞秒激光脉冲轰击普通金属,研发出一种新型表面材料,它可以有效吸收光能、防水以及自我净化。这种多功能材料可用于制造高耐用、低保养的太阳能集热器和太阳能传感器。“这是首次使用激光制造出的多功能金属表面材料,该材料具有超疏水(防水)、自我净化及高吸收等多重功能。”罗切斯特大学光学院物理学家郭春雷说。郭春雷与同事Anatoliy Vorobyev共同研发了该新型材料。 Researchers at the University of Rochester in New York, USA developed a new surface material that efficiently absorbs light, wicks water and self-purifies by bombarding common metals with femtosecond laser pulses. This versatile material can be used to make highly durable, low maintenance solar collectors and solar sensors. “This is the first multi-functional metal surface material made of laser, which has multiple functions of superhydrophobicity, self-purification and high absorption,” said Guo Chunlei, a physicist at the University of the Rochester. Guo Chunlei and his colleague Anatoliy Vorobyev jointly developed the new material.
