Ice adhesion properties of periodic surface microtextured optically transparent superhydrophobic polydimethylsiloxane

There is a need for optically transparent surfaces which repel water and eliminate ice formation in applications, such as solar power generation. Surface microtexture has played an important role controlling wetting properties adhesion pressure. Here we report the effect of periodic surface on pressure Polydimethylsiloxane. Laser ablation was used to produce aluminum substrate transferred onto polydimethylsiloxane (PDMS) via hot embossing. The control laser processing patterns with smooth area from 53.8% 89.6% enabled fine-tuning properties. PDMS grid pattern proven be superhydrophobic exhibited low 60.1 kPa, allowing achievement repellent anti-icing surface. microtextured were quantified by measurement receding contact angle (RCA), hysteresis (CAH), Various publications have pointed ROA, RCA, or CAH predictor pressures surfaces. For surfaces, it found that most accurate • An icephobic been achieved. Ice strength correlates well rather than angle. Low prepared irradiation embossing replication.
