摘要：
The invention relates to water-repellent composite grains. Each composite grain includes: a first grain; and a low molecular weight polytetrafluoroethylene (PTFE) covering the first grain. The first grain is higher than the PTFE in mechanical strength. With this, the composite grains are improved in mechanical strength. A water-repellent article is produced by anchoring the composite grains to a substrate through an adhesive layer formed on the substrate. The composite grains are partly exposed on the adhesive layer and partly submerged in the adhesive layer. With this, the water-repellent article is made minutely rough. The water-repellent article is improved in mechanical strength and water repellency.
