We reported a novel method to fabricate both spherical and nonspherical PDMS (Polydimethylsiloxane) particles of amphiphilic property. PDMS particles were first obtained using microfluidic devices. A layer of PAA (poly (acrylic acid)) polymer was then selectively grafted on a section of particle surface. After modification, PDMS particles exhibited an amphiphilic property. We demonstrated the assembly of spherical particles at the water/oil interface as well as the deformation of cuboidal particles which possessed a bowl-shaped structure after deformation.
