원형 미세 홀 어레이를 가진 니켈 메쉬 시트의 방수 특성 및 응용가능성 평가

Nickel micromesh sheets with circular microhole array were designed and fabricated and their water-proof abilities were characterized. The micromesh enabled the material waves, including sound and light waves, to pass through the microholes, but repelled water. Reducing the hole size and increasing the lattice width of the micromesh are necessary to improve the water-proof ability.
