This project aims to achieve the efficient functionalization of the silica microparticles via ATRP reaction in flow reactor. The continuous flowing of different monomers makes this methodology efficient and universal for grafting different polymer structures from silica microparticles according to various needs. Firstly, a linear PNIPAM polymer brush was grafted from silica microparticles to prove this methodology work. Then hyperbranched polystyrene chain ends were attached onto the PNIPAM-functionalized microparticles. The reaction times of both steps were studied to elucidate the relation between flow time, molecular weight and polydispersity of the polymer. FTIR, TGA, NMR, and GPC techniques were utilized to characterize the functionalized silica microparticles and the polymer shell. Finally, branched PDMAEMA brushes were grafted from the silica microparticles to set an actual example for this methodology as it could easily produce the functionalized silica microparticles with dual-responsive properties. Dye absorption and contact angle tests were conducted to prove the potential applications of the functionalized particles.
