  Wettability is a fundamental physicochemical property of solid surfaces, with
unique wettability patterns playing pivotal roles across diverse domains.
Inspired by nature's ingenious designs, bio-inspired materials have emerged as
a frontier of scientific inquiry. They showcase remarkable hydrophobic
properties observed in phenomena such as mosquitoes preventing fog
condensation, and lotus leaves exhibiting self-cleaning attributes. This
groundbreaking research delves into the hydrophobic characteristics of
biomimetic surfaces using coarse-grained molecular simulation and the free
energy barrier evaluation system. By analyzing the butterfly wings and mosquito
eyes model, we aim to pioneer a comprehensive framework that factors in the
influence of surface parameters on the free energy barrier. Through meticulous
simulation and analysis, we strive to validate and enhance the reliability of
the free energy barrier assessment method, deepening our understanding of
hydrophobicity across diverse biomaterials and paving the way for optimizing
their properties for a myriad of applications. During our investigation, we
shed light on the elusive intermediate state, a departure from the typical
Cassie or Wenzel state, enriching our theoretical framework for surfaces with
distinctive properties. This research is a catalyst for developing biomimetic
materials with superior hydrophobic characteristics and innovative fabrication
processes, transcending academic boundaries and promising significant strides
in environmental conservation, medicine, and beyond, offering hope for a
greener, healthier, and more sustainable future.
