My paper on the self-cleaning of gecko adhesives was published in Applied Materials and Interfaces. We reported that for certain particle sizes and fiber diameters, both hard (polypropylene) and soft (PDMS) fibrillar adhesives recover adhesive capabilities to different degrees. An analysis of the contact strength between fibers, particles and substrates reveals that dry self-cleaning is more effective for smaller fiber diameters and smaller loss functions, such as hard thermoplastics.
