弹性基底上软物质梁的弹性毛细变形
Elastocapillary Deformation of Soft Matter Beams on Elastic Substrate
摘要
Abstract
With droplets on the surface of soft matter or micro/nanostructures,wetting-induced elastocapillary deformation should be considered.Based on a new wetting equation,the relationship between the droplet spreading radius and its surface curvature was determined,and the necessary conditions for the droplet to hold the spherical cap without the influence of gravity were obtained.Combined with the Winkler foundation model,the elastocapillary deformation of soft material microbeam on elastic substrate was calculated.The analytical solution for the deflection of the microbeam was given.With polystyrene and polyethylene beams as examples,the influences of the droplet spreading radius,the beam material elastic modulus and the Winkler foundation parameter on the microbeam deflections and detachments from the substrate,were analyzed and discussed.关键词
