“…To date, a variety of hierarchically structured particles have been prepared, mainly including dumbbell shape, popcorn shape, strawberry shape, , and so on. Owing to the rough surface morphology and large specific surface area, , these particles have been extensively studied and applied in many areas, such as superhydrophobic coating, drug delivery, catalyst carriers, , environmental protection, and nanocomposites . Among them, superhydrophobic coating (water contact angle ≥ 150°) plays an increasing importance in applications, such as antifouling, self-cleaning, and anti-icing. , …”
