“…This fact was underlined by the decrease of the absorption bands at 3037, 1635 and 1408 cm -1 and the concomitant development of new bands at 2935 and 1452 cm -1 assigned to methylene groups. Such post-polymerization was also observed in previous studies performed on the two homopolymers synthesized from the photopolymerization of the corresponding acrylate monomers [25]. It is relevant to mention that the same experiment performed in the absence of oxygen also led to the same features.…”

“…These gases were also detected in the case of the irradiation of homo-PETTA and homo-2EEEA [25]. Their formation was explained by chain scission reactions (Norrish I cleavage and ester elimination reactions) that took place both on PETTA and 2EEEA units [49,50].…”

“…In the present study, the matrix was stemming from the polymerization of a mixture of acrylate monomers consisting of pentaerythritol tetraacrylate (PETTA) and 2-(2-ethoxyethoxy)ethyl acrylate (2EEEA). As a consequence, the whole structure of the synthesized PETTA/2EEEA copolymer was rather complex and so, assessing its stability required in a first approach to evaluate the resistance to ageing of each of the two homopolymers (carriers of different functional groups) synthesized from the corresponding acrylate monomers [25]. It was established that the combined effect of light and oxygen caused both the post polymerization of the residual vinyl groups of the acrylate units and the degradation of the polymer network.…”

ZnO quantum dots, QDs (5 nm diameter) by their photogenerated charge carriers clearly influence the degradation of the acrylate host matrix, under conditions simulating solar light.As a result, QDs undergo a partial quenching of their fluorescence. To rationalize this influence, the investigation requires understanding the photochemical behavior of the acrylate photopolymer (carrier of ester and ether groups) in the absence of nanofiller. The matrix undergoes simultaneously a post-polymerization and photooxidative degradation. Infrared analysis and headspace gas chromatography coupled with mass spectrometry reveal that the main volatile organic compounds result from the oxidation of the ether groups, supposed to be the primary sites of degradation.The nanofiller increases the rate of degradation. Also, the concentration of the volatile organic compounds is all the more important as the doping percentage increases. However, the photostability of ZnO/polymer material strongly depends on the size of the nanoparticles.Whereas ZnO QDs display a photocatalytic effect, nanoparticles with a bigger size (10-30 nm) exhibit an unexpected UV-screening effect.

The present work aims to investigate the impact of a low amount of photo-induced silver nanoparticles (0.2 and 0.4 wt.% of Ag NPs) on the stability of acrylate materials (carriers of ester and ether groups) under the combined effect of oxygen and light. Different techniques were implemented to monitor the structural changes at different scales. The determination of the influence of AgNPs required a preliminary investigation of the pure acrylate polymer under the same experimental conditions. The polymer underwent a post-polymerization of the residual vinyl groups and a photo-oxidative degradation. This degradation induced chemical modifications evidenced by infrared spectroscopy and architectural changes resulting from chain scission reactions. These reactions were not only responsible for the steaming of volatile organic compounds, detected by HS-SPME/GC-MS but also for the increase in mesh size controlled by thermoporosimetry. As regards the polymer/Ag NPs composite, the higher the amount of filler dispersed in the matrix, the greater the rate of degradation. This behaviour was due to the photocatalytic effect of Ag NPs, regardless of the loading in nanoparticles. As a result of irradiation, the nanoparticles migrate to the surface of the film and coalesce, thus inducing an increase in size distribution and a gradient structuring as revealed by TEM analysis. The outcomes of this investigation are important for the development of new composite material with new functionalities (antibacterial, optical, conductive properties) for industrial applications as in textile industry.
