“…These bonds are all present in the ester functionality, again lending support to the theory of monomer structure retention. [33] XPS was also performed on the PECVD PHEMA to confirm the atomic makeup of the film. The 2.59 eV full width at half maximum (FWHM) of the oxygen 1s peak versus the FWHM minimum of 1.6 eV suggested the expected multiple bonding states corresponding to the three different oxygen bonding types in the film; carbonyl(C --O Ã ), hydroxyl(O Ã -H), and ester functional groups(CO-O Ã -CH 2 ).…”

Plasma Enhanced Chemical Vapor Deposition (PECVD) of poly-2-hydroxyethyl methacrylate (pHEMA) biocompatible, biodegradable polymer films were produced alone and cross-linked with ethylene glycol diacrylate (EGDA). Degree of cross-linking was controlled via manipulation of the EGDA flow rate, which influenced the amount of swelling and the extent of degradation of the films in an aqueous solution over time. Noncross-linked pHEMA films swelled 10% more than cross-linked films after 24 h of incubation in an aqueous environment. Increasing degree of film cross-linking decreased degradation over time. Thus, PECVD pHEMA films with variable cross-linking properties enable tuning of gel formation and degradation properties, making these films useful in a variety of biologically significant applications.

“…The oxygen atoms with a lone pair of electrons act as electron donor atoms in the structure of the polymer host. The interaction between the oxygen atoms and lithium ions of the metal salt forms a coordinate bond and generates polymer-salt complexes [5,6]. Previous studies on various MG were reported elsewhere [5,7,8].…”

Abstract:The studies of rubber-polymer blends as solid polymer electrolyte for electrochemical devices application have been investigated. The electrolyte films were prepared by solution casting technique. The effect of poly(methyl methacrylate) (PMMA) and lithium tetrafluoroborate (LiBF 4 ), salt concentration on chemical interaction, ionic conductivity, structure and morphology of 49% poly(methyl methacrylate)-grafted natural rubber (MG49) have been analyzed by using fourier transform infrared spectroscopy (FT-IR), electrochemical impedance spectroscopy (EIS), x-ray diffraction (XRD) and scanning electron microscopy (SEM). Infrared analysis showed that the interaction between oxygen atoms and lithium ion occurred at ether (C-O-C) and carbonyl (C=O) group in the MMA host. The highest ionic conductivity for blended MG49-PMMA films is 8.3 10 -6 S cm -1 as compared to MG49 electrolyte with 9.6 10 -10 S cm -1 at 25 wt. % LiBF 4 . The structural analysis showed the reduction of MMA crystallinity phase at the highest conductivity for both systems. Meanwhile, morphological analysis shows that recrystallization of LiBF 4 salts have occurred in the electrolyte system after the optimum conductivity.

Elastomers

View full text Add to dashboard Cite

Elastomers refer to natural or synthetic amorphous polymers which exhibit elastic properties of rubber. Elastomers are able to deform under stress and return to its original state upon removal of stress. As elastomers exhibit glass transition temperatures (T g ) below room temperature (r.t.), elastomers are soft and rubbery at r.t, and segmental motion exists. Elastomers, which contain polar atoms, such as oxygen (O), fluorine (F) and nitrogen (N), can be suitably employed as matrices in polymer electrolytes (PEs). The electronegative atoms serve as electron donors and are able to coordinate with cations from inorganic salts to form a complex. Among elastomers that have been employed in PEs include modified and copolymerised polyisoprene or natural rubber, polyurethanes, and polysiloxanes. This chapter focuses on the progress of natural rubber and its derivatives in the field of polymer electrolytes, and discussesc their interactions with other components of the PEs and ion conduction. Area percentage of ionic species, as well as ion transport parameters, such as number density, mobility and diffusion coefficient of lithium ions as obtained from deconvolution of infrared (IR) spectra, are also discussed in this book chapter.
