Abstract Functional microspheres with silicone were obtained by the hydrosilylation reaction using the silicon hydrogen bonds on the surface of the micrometer-scale silicone rubber microspheres and the carbon-carbon double bonds on the surface of the nanometer-scale silicon dioxide. The amount of silicon dioxide was considered for the hydrophobicity of functional microspheres. The results showed that the surface of silicone rubber microspheres coated with nano-silica aggregates, and it formed micro-nano structure. The data of contact angle results demonstrated that the contact angle of sample reached 150°. With the increased amount of silicon dioxide with carbon-carbon double bonds, the data of contact angle slightly increased and tended to be stable.
