Still, their stacking and aggregate behavior can limit their practical application. To address this issue, reversible addition–fragmentation chain-transfer (RAFT) polymerization as controlled radical polymerization was applied to functionalize the surface of graphene oxide with poly(<i>N</i>,<i>N</i>-dimethylaminoethyl methacrylate) (PDMAEMA) via the ‘grafting from’ method. This strategy enhances the distance between graphene sheets by occupying physical volume while improving effective charge transfer through tertiary amine groups participating in the doping process. X-ray diffraction was used to determine interlayer spacing after polymer grafting, which increased from 0.28 to 1.71 nm after polymer grafting. The hybridization of materials with diverse properties was used to enhance charge transfer capability for supercapacitor applications. PDMAEMA-functionalized graphene oxide, nano-manganese dioxide and polyaniline were combined to create a successful nanocomposite as electrode active material. The morphological structure and chemical composition of the synthesized nanocomposite were analyzed, and its electrochemical performance was evaluated using cyclic voltammetry, galvanostatic charge–discharge and electrochemical impedance spectroscopy. The nanocomposite exhibited a maximum specific capacitance, energy density and power density of 364.72 F g<sup>−1</sup> (at a scan rate of 50 mV s<sup>−1</sup>), 239.08 Wh kg<sup>−1</sup> and 678.34 W kg<sup>−1</sup>, respectively.

In this work, three commercial biodegradable (and, at least partially, biobased) polymers were investigated by a preliminary rheological and mechanical analysis, in order to perform film manufacturing experiments in laboratory equipment. Furthermore, oxygen and water vapour barrier properties were studied by permeability measurements. The investigation was ultimately performed on films produced in industrial equipment, and the results were compared to those for a typical, standard polypropylene (PP) film used in flexible packaging applications. It was found that the mechanical properties were adequate (in some cases, even up to 25–30% higher than for the PP counterpart), as well as oxygen permeability.

Carbon fiber (CF) polymer–matrix structural composites have relatively high in-plane thermal conductivity but low through-plane conductivity. In order to further enhance the through-plane and in-plane conductivity of CF-reinforced polybutylene terephthalate (PBT) composite, a hybrid loading approach was employed, incorporating synthetic graphite (SG), boron nitride (hBN), aluminium nitride (AlN) and graphene (G) in composite formulations. It was found that the in-plane conductivity of PBT-20CF-20SG-3G and the through-plane conductivity of PBT-20CF-20SG-3AlN are 69% and 25% higher, respectively, than those of PBT-40CF. However, the mechanical properties of hybrid composites exhibit lower values compared to those of CF-reinforced PBT composites. The tensile strength value of PBT-40CF is about 33% and 57% higher than those of PBT-20CF-20SG-3G and PBT-20CF-20SG-3AlN. Moreover, the flexural strength of PBT-40CF is about 48% and 38% higher than those of PBT-20CF-20SG-3G and PBT-20CF-20SG-3AlN, respectively. The density value of PBT-40CF is lower than that of the composites of PBT-20CF-20SG. From TGA it was observed that the thermal stability of PBT-40CF is comparable to that of the composites PBT-20CF-20SG. From the conducted study, it can be proposed that the hybrid combination of SG, hBN, AlN and G can be utilized to achieve higher thermal conductivity values, instead of relying solely on CF in the composites. © 2024 The Authors. <i>Polymer International</i> published by John Wiley &amp; Sons Ltd on behalf of Society of Industrial Chemistry.</p>","PeriodicalId":20404,"journal":{"name":"Polymer International","volume":"73 6","pages":"484-493"},"PeriodicalIF":3.2,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pi.6622","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139923381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
