The ice-phobic and transparent surface based on the distinctive structure of a coating material has been investigated. Moth eye structure fabricated on the quartz substrate was covered with a flat paraffin layer to isolate it in a cold and humid environment. Paraffin wax was chosen as the coating material due to low thermal conductivity. easy coating. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC550-WUH721816ALE6L0-0F38460-16TB-7-2K-RPM-SATA-6Gb-s-512e-ISE-3-5in-Hard-Drive/
