“…The degradation of pure PVDF under X-rays or electron beam is proposed to occur through de-hydrofluorination, forming radical species such as F* and H* by-products. 26,35,36 In agreement with the literature, we observe partial fluorine loss as highlighted by the decrease of the overall F 1s area with respect to C 1s (inset panels in Figure 3a,b). Since the reaction of a CF 2 group requires the presence of an adjacent CH 2 , the kinetics of the process have been proposed to be of the second order, although the details are still not clear due to the influence of polymer crystallinity and morphology.…”

We investigated the effects of X‐ray beam damage during X‐ray photoelectron spectroscopy measurement on LiNiO2 electrodes. The degree of damage induced by lab‐based and synchrotron X‐ray radiation has been compared between pristine and cycled electrodes, highlighting the role of positive solid electrode–electrolyte interphase to protect the cycled LiNiO2 surface from beam damage. The possible steps to avoid or at least reduce the beam‐induced effects are outlined.

“…3) revealed typical signals corresponding to the aliphatic and aromatic contributions (C-C/C-H), C-O, C-S, COO, and CF 3 functionalities, which agree with the data previously obtained for the MAPDST homopolymer and MAPDST-MMA copolymers. 15,21,[35][36][37] The S 2p spectrum of the untreated 2.15% MAPDSA-MAPDST surface shows four spinorbit split doublets, having binding energies that are characteristic of S-C, 38,39 S]O, SO 3 , and SO 4 . 40 The presence of four contributions in the S 2p envelope was necessary to t the experimental signal, which probably could be caused by a possible partial oxidation/degradation of the resists.…”

“…Meanwhile, another characteristic absorption peak also appeared at 1720 cm -1 , resulting from the carbonyl stretching vibration produced by the oxidation reaction. There have been some studies on the degradation process of PVDF, which mainly includes oxidation reaction and the decomposition of HF [49][50][51][52].…”

Material degradation has marked impact on the long-term properties and service life of membrane structures. This study is aimed at assessing and understanding the deterioration in visual aspect, surface microstructure, and mechanical properties of a polyvinylidene fluoride (PVDF) polymer after engineering applications. Three groups of PVDF-coated fabrics were removed from different membrane structures in China, which have been used for 15, 16, and 19 years, respectively. Firstly, spectrocolorimetry tests were carried out to determine the evolution of chromaticity and lightness. Other methods such as contact angle and thickness measurements were used to characterize the physical properties. Then, surface morphology was observed by using scanning electron microscope (SEM) technology. Moreover, a series of uniaxial tensile tests and tearing tests were performed to obtain the mechanical indicators including uniaxial tensile strength, strain at break, tearing strength, and uniaxial elastic modulus. In order to further study the degradation mechanism, infrared spectroscopy was used to characterize the molecular structure of aged fabrics. Finally, Principal Component Analysis (PCA) provided a comprehensive description of correlations between surface microstructure, physical properties, and mechanical properties. This paper offers a further understanding of the design, qualification, and durability evaluation of membrane structures.
