Surface modification has been numerously required to nano/microparticles since many characteristic of small size nano/microparticles are determined by surface property. Here we introduce a one-step and kilogram scale surface modification method of metal-oxide particles. By simple ball milling of metal-oxide particles with trimethyl-terminated polydimethylsiloxane(m-PDMS), hydrophobic PDMS brush is grafted on the surface of the metal-oxide particles. Since m-PDMS is chemically identical with polysilicone, the PDMS grafted metal-oxide particles have a good compatibility with other PDMSs. Therefore, high metal-oxide particle concentration of metal-oxide/PDMS composite can be prepared with no phase separation that opens a door to realize composites of high filler ratio for various research and applications. |
