Abstract

En 中文
• A negative-defocus strategy of nanofibrous laser-induced graphene fabrication. • Nanofibrous structure achieved the highest reported capillary height and velocity. • Capillary height reaches 120 mm in 46 s, with a wicking velocity of 21.71 mm·s-0.5. • Ultrathin vapor chamber achieves thermal conductivity of 1225.6 W/(m·K)
Keywords:
