2005年12月1日 · XPS measurements of polydiallyl phthalate recorded with a SSX-100 spectrometer in standardized experimental conditions are presented: survey scan, high resolution core level spectra as well as...

2023年1月1日 · The elemental composition and surface chemistry of PVC and PVC-PEI were investigated by XPS. In compared with PVC, the XPS survey spectrum of PVC-PEI offers a new signal of N, confirming the introduction of PEI in the cross-linking reaction (Fig. S7). At the same time, the intensity of Cl signal was significantly reduced in PVC-PEI.

2023年1月1日 · In this work, a polyethyleneimine-modified chitosan/Ce-UIO-66 composite hydrogel (PEI-CS/Ce-UIO-66) was prepared using the ex-situ blend method. The synthesized composite hydrogel was characterized by SEM, EDS, XRD, FTIR, BET, XPS, and TG techniques, while the zeta potential was recorded for sample analysis.

2009年7月15日 · PEI with a mean molar mass of 2000 g mol −1 provides the best protection against localized corrosion, as demonstrated by cyclic polarization measurements. A closer insight into the polymer adsorption was obtained by XPS technique.

2016年1月11日 · Polyethylenimine (PEI) is a cationic polymer able to interact with nucleic acids. Taking advantage of this property, PEI-modified functional surfaces for the capture of DNA were developed and characterized with X-ray photoelectron …

2016年1月11日 · 利用这一特性，在制备的每个步骤中，开发了用于捕获DNA的PEI修饰的功能表面，并通过X射线光电子能谱（XPS）进行了表征。 XPS证明功能表面上存在PEI，而PEI伯氨基的密度通过比色法定量，结果为6×10 14个氨基/ cm 2。 不同数量的DNA吸附在功能表面上，并且通过荧光和XPS监测DNA和PEI之间的相互作用。 功能表面确实能够捕获DNA，从而为低成本，快速的DNA纯化策略提供了可能性。 版权所有©2016 John Wiley＆Sons，Ltd. Polyethylenimine …

Polyethylenimine (PEI) is a cationic polymer able to interact with nucleic acids. Taking advantage of this property, PEI-modified functional surfaces for the capture of DNA were developed and characterized with X-ray photoelectron spectroscopy (XPS) during every step of the preparation.

2006年12月18日 · XPS measurements of poly (ethylene imine) recorded with a SSX-100 spectrometer in standardized experimental conditions are presented: survey scan, high resolution core level spectra as well as the energy loss regions of carbon and nitrogen peaks are analyzed.

该团队进一步介绍，pei-zn材料同时具备优异的光电性能、化学稳定性和机械柔性，既能与多种印刷电极（包括agnws和pedot:pss电极）相兼容，又能与非富勒烯活性层体系（pbdb-t-2f:it-4f和pbdb-t-2f:y6）相兼容，在柔性电子和印刷电子领域有重要意义。
