Thermoresponsive hybrid particles of SiO2-PNIPAM (PNIPAM: poly(N-isopropyl acrylamide) were synthesized by surface initiated atom transfer radical polymerization (SI-ATRP). The structure of hybrid particles was characterized by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The grafting ratio of PNIPAM on the silica surface was about 103.7% as measured by thermogravimetric analysis (TGA). The thermoresponsive behavior of monodisperse hybrid particles wasdoi:10.3866/pku.whxb201512111 fatcat:4zznetuvpreh3ivlyp6erpc7pm
