“…5). Unfortunately, we could not observe the C-Br stretching vibration at 571, 640 and 661 cm À 1 with ATR/FT-IR spectroscopy due to the wavelength limit of the detector [25]. The structure of PPMM-N 3 is supported by the observation from the ATR/FT-IR spectrum of the azide stretching band at 2100 cm À 1 [11,[27][28][29], indicating the successful exchange of Br atoms in PPMM-Br with azide groups in NaN 3 .…”

“…The flask was placed in front of 2×300 W high-pressure mercury vapor lamps at a distance of 7 cm. 17 Then UV-irradiation was performed for a specified time. The un-reacted bromine was removed by ammonia washing and then the product was kept in a vacuum oven at room temperature for 25 h. The brominated PVDF was designated as PVDF-Br, the Br atoms in which were served as initiation sites for ATRP reaction.…”

Controlled grafting of well-defined polymer brushes of methyl methacrylate (MMA) on the poly(vinylidene fluoride) (PVDF) powders was carried out by the surface-initiated atom transfer radical polymerization (ATRP). The ATRP initiator was anchored on the PVDF surface by alkaline treatment, followed by UV-induced bromination; then methyl methacrylate (MMA) was grafted onto the brominated PVDF by the ATRP technique. The chemical composition changes of PVDF were characterized by Fourier transform-infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). FT-IR and XPS results clearly indicated the successful graft of poly(methyl methacrylate) onto the PVDF surface.

Many applications require polymeric materials to be in contact with other materials or with specific environments. In this respect, the surface and interface properties of polymers cannot be overemphasized. This article describes, reviews, and updates the three most common surface modification techniques for synthetic polymers, viz, (i) plasma modification, (ii) surface grafting and graft polymerization, and (iii) chemical modification and reaction. Plasma modification involves surface energetic interactions, as well as plasma polymerization and deposition. Surface modification via grafting and graft polymerization generally involves the “grafting to” and “grafting from” approaches. The latter approach has been made even more versatile by the development of surface‐initiated controlled radical polymerizations in the late 1990s. Chemical modification of polymer surfaces includes ozone treatment, chemical and electrochemical redox reactions, sulfonation and halogenation, photochemical reactions, biologically influenced modification, and layer‐by‐layer coating. Finally, the effects of physical structures of modified surfaces are briefly discussed.
