“…[5][6][7] Typically, polymer chain grafting is performed by attaching polymer chains that are able to bind to substrates, the so-called 'grafting-to' approach, or by polymerizing monomers from the substrate surface, the so-called 'grafting-from' approach. 8 The 'grafting-from' method is often preferable for producing a thick polymer layer consisting of densely surface-tethered polymer chains.…”

Direct surface modification of polymer fibers and films by surface-initiated polymerization has been investigated. The introduction of initiating sites on polymer materials and their successive polymerization produce surface-tethered polymer chains on the polymer surface. The surface-selective modification controls the surface properties, such as wetting, lubrication and antifouling, without sacrificing bulk performance. Among the various procedures for introduction of initiating groups and subsequent polymerization proposed to date, this focused review article highlights our studies on polymer brush grafting to electrospun polymer fibers and polymer films through surface-initiated polymerization. We review studies focusing on grafting polymer chains to five different types of solid polymers: poly(methyl methacrylate)-based copolymers, Br-containing polyolefins, poly(vinylidene fluoride-co-trifluoroethylene), poly(butylene terephthalate), and poly(ether-ether ketone).

“…13 The second method employs high-energy sources including plasma, irradiation, and corona to activate the Teflon surface. 15,16 For example, Chu et al adopted plasma treatment to change both the morphological and chemical structures of PTFE surface on which osteoblast 17 and mesenchymal stem cell 18 behaviors were well tailored. In addition, Lee et al conducted sensitive DNA detections on functionalized FEP substrate by treating the inert surface with ion implantation and graft polymerization.…”

This paper presents a convenient strategy to modify the surface of whole-Teflon microfluidic chips by coating the channel walls with a thin layer of polydopamine (PDA) film, which is formed by oxidation-induced self-polymerization of dopamine in alkaline solution. Two coating strategies, static incubation and dynamic flow, are demonstrated and used for tuning the physical and chemical properties of the coated channel walls. The functionalized surfaces were investigated with the contact angle, X-ray photoelectron spectroscopy, and atomic force microscopy measurements. The coating time was optimized according to the fluorescent intensity of the green fluorescent protein immobilized on the modified surface. Applications of the PDA-modified Teflon microchips in bioanalysis were demonstrated with a typical sandwich immunoassay. Moreover, long-term cell culture experiments on modified and native Teflon chips revealed that the chip biocompatibility can be greatly improved with PDA coating. The results indicate that the surface properties of the Teflon can be easily controlled by the PDA modification, thus greatly expanding the application scope of whole-Teflon chips for various chemical and biological research fields.

“…[1][2][3][4][5][6] Many advanced applications of ultrathin polymer films can be envisioned, such as all polymeric semiconducting devices and direct-write lithography [5,6]. Currently, the most common method to prepare thin polymer films is by wet techniques, such as electrochemical deposition, spin coating.…”

“…The characterizations of the films were carried out using ex-situ Fourier transformationinfrared-reflection absorption spectroscopy (FT-IR-RAS), X-ray photoelectron spectroscopy (XPS), optical microscopy and atomic force microscopy (AFM). Figure 1 shows FT-IR-RAS spectra of 6-diallylamino- [1,3,5]triazine-2,4-dithiol (DA) thin films of 50 nm UV irritated at various times. Table 1 summarizes the main absorption bands found in the spectra and their associated vibration modes.…”

Abstract:In this study, polymer thin films were prepared and patterned by vapor deposition photo-polymerization of 6-diallylamino-[1,3,5]-triazine-2,4-dithiol) on SiO 2 /Si substrates. The characterizations of these films were investigated using FT-IR-RAS, XPS, optical microscopy and AFM. The polymerization rate of 0.10 ~ 0.14 min -1 was obtained by an ex-situ FT-IR-RAS study. The structure characterized with XPS showed that the polymer films contained disulfide bonds produced by thiol groups, and monosulfide bonds produced by the reaction between allyl and thiol groups and formed network chains. Furthermore, the 2.19 μm pattern of lines and spaces was developed sufficiently by optical observation.
