The feasibility of polyethylenimine (PEI)-impregnated millimeter-sized mesoporous carbon spheres (MCSs) for post-combustion CO2 capture is systematically studied over a wide range of adsorption...

2014年9月1日 · The high performance of polyethyleneimine (PEI)-based solid adsorbent for CO 2 capture has been well recognized in thermogravimetric analysis (TGA) and small-scale fixed bed reactors through the measurements of their equilibrium capacities but has not been really demonstrated on larger scales towards practical utilization.

2018年8月1日 · PEI/PC blends obtained with a batch mixer were characterized by the means of Thermogravimetric (TG) and Differential Thermogravimetric (DTG) analysis and Differential Scanning Calorimetry (DSC). The parameters associated with the physical properties of the various blends were evaluated and compared with those obtained for the pristine polymers.

The thermal degradation behavior, chemical structure and morphology of the PEI mats were characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR) and...

2007年6月27日 · The thermal degradation behaviours of a novel aromatic poly(ester–imide) (PEI) derived from pyromellitic dianhydride and 2,7-bis(4-aminobenzoyloxy)naphthalene have been investigated by thermogravimetric analysis (TGA) and by pyrolysis–gas chromatography/mass spectrometry (pyrolysis–GC/MS).

2011年11月1日 · The successful surface modification of MNPs was confirmed using X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and fourier transform infrared (FTIR) measurements. The modified MNPs interact strongly with negative fibrinogen and weakly with neutral γ-globin and positive lysozyme.

Thermogravimetric Analysis (TGA) - measures weight changes associated with thermal events. While TGA is most commonly used to determine compositional analysis, it is also valuable for determining thermal stability.

We present a comprehensive thermogravimetric analysis (TGA) of polyethylenimine (PEI)-impregnated resorcinol-formaldehyde (RF) aerogels. While numerous studies focus on PEI-impregnated SBA, RF materials have been less examined, despite their interest and specificities.

2023年7月11日 · 热重分析(tga)是—种常用的材料表征方法，可以用于研究材料的热分解行为和热稳定性。在pei聚醚酰亚胺的热重分析中，我们可以通过测量样品在加热过程中的质量变化来了解其热分解行为。

Figure 8 shows the TGA curves of the PEIs, evaluated under N 2 atmosphere. The polymers show 5% weight loss at temperatures ranging from 318 C to 418 C as shown in Table 1. ...
