摘 要：正Microphase separation behavior on the surfaces of poly（dimethylsiloxane）-block-poly （2,2,3,3,4,4,4-heptafluorobutyl methacrylate）（PDMS-b-PHFBMA） diblock copolymer coatings was *** PDMS-b-PHFBMA diblock copolymers were successfully synthesized via atom transfer radical polymerization（ATRP）.The chemical structure of the copolymers was characterized by nuclear magnetic resonance（NMR） and Fourier transform infrared（FTIR） *** composition was studied by X-ray Photoelectron Spectroscopy（XPS）.Copolymer microstructure was investigated by atomic force microscopy（AFM）.The microstructure observations show that well organized phase-separated surfaces consist of hydrophobic domain from PDMS segments and more hydrophobic domain from PHFBMA segments in the *** increase of the PHFBMA content can strengthen the microphase separation behavior in the PDMS-b-PHFBMA diblock *** the increase of the annealing temperature can also strengthen the microphase separation behavior in the PDMS-b-PHFBMA diblock ***, Flory-Huggins thermodynamic theory was preliminarily used to explain the microphase separation behavior in the PDMS-b-PHFBMA diblock copolymers.
