    Quantification of grafted poly(ethylene glycol)-silanes on silicon by time-of-flight secondary ion mass spectrometry
    摘要:
    采用静态飞行时间二次离子质谱法(TOF-SIMS)对具有不同 PEG 链长的硅接枝单分散聚乙二醇(PEG)硅烷及其混合物进行了系统分析。质谱显示了各种相对信号强度的差异,这一观察结果可用于阐明接枝过程的重要方面。PEG - 硅烷碎片离子丰度与 Si+ 离子丰度之间的关系被用于:(i) 定性描述硅上 PEG - 硅烷接枝混合物的层厚度;(ii) 构建校准曲线,从而确定 PEG 链长(或分子质量);(iii) 定量确定不同链长(3、7 和 11 个 PEG 单位)的接枝单分散 PEG - 硅烷的表面混合物成分。结果表明,在吸附过程中确实发生了分化。在含有 PEG3 硅烷的混合物中,PEG 链较短的 PEG 硅烷会被分辨出来,而在 PEG7/PEG11 硅烷混合物中,PEG 链较长的 PEG 硅烷会被分辨出来。造成这种吸附行为差异的原因尚不清楚。本文讨论了接枝过程和 TOF-SIMS 分析的各个方面。Copyright © 2002 John Wiley & Sons, Ltd.

  • Volume Fraction of Ether Is a Significant Factor in Controlling Conductivity in Proton Conducting Polyether Based Polymer Sol–Gel Electrolytes
    作者:Benjamin Yancey、Jonathan Jones、Jason E. Ritchie
    DOI:10.1021/jp5072082
    日期:2014.11.13
    We have synthesized several copolymers of methyl polyethylene glycol siloxane (MePEG(7)SiO(3))(m) and methyl polypropylene glycol siloxane (MePPG(n)SiO(3))(m) as hydrogen ion (H+) conducting polymer electrolytes. These copolymers were prepared by a solgel polymerization of mixtures of the MePEG and MePPG monomers. We synthesized these H+ conducting polymer electrolytes in order to study the relationship between observed ionic conductivity and structural properties such as viscosity, fractional free volume, and volume fraction of ether. We found that viscosity increased as the fraction of the smaller comonomer increased. For the MePPG(2)/MePPG(3) copolymer, an increase in fractional free volume increased the fluidity. The heterogeneous copolymers (PEG/PPG copolymers) obeyed the Doolittle equation, while the homogeneous (PEG/PEG and PPG/PPG) copolymers did not. The increase of FFV did not, however, correspond to an increase in conductivity, as would have been predicted by the Forsythe equation. The conductivity data did correspond to a modified Forsythe equation substituting Volume Fraction of Ether (V-f,V-ether) for FFV. We conclude that the proton conductivity of MePEG copolymers is more dependent on the volume fraction of ether than on the fractional free volume.
  • Quantification of grafted poly(ethylene glycol)-silanes on silicon by time-of-flight secondary ion mass spectrometry
    作者:K. Norrman、A. Papra、F. S. Kamounah、N. Gadegaard、N. B. Larsen

    Silicon grafted monodisperse poly(ethylene glycol) (PEG) silanes with various PEG chain lengths and mixtures of these were systematically analyzed with static time-of-flight secondary ion mass spectrometry (TOF-SIMS). The mass spectra show differences in the various relative signal intensities, an observation that was used to elucidate important aspects of the grafting process. The relationship between PEG-silane fragment ion abundances and Si+ ion abundances were used to (i) qualitatively describe layer thicknesses of grafted mixtures of PEG-silanes on silicon, (ii) construct a calibration curve from which PEG chain length (or molecular mass) can be determined and (iii) quantitatively determine surface mixture compositions of grafted monodisperse PEG-silanes of different chain lengths (3, 7 and 11 PEG units). The results suggest that discrimination does take place in the adsorption process. The PEG-silane with the shorter PEG chain is discriminated for mixtures containing PEG3-silane, whereas the PEG-silane with the longer PEG chain is discriminated in PEG7/PEG11-silane mixtures. The origin of this difference in adsorption behavior is not well understood. Aspects of the grafting process and the TOF-SIMS analyses are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
