However, traditional methods to enhance the mechanical properties of ionic hydrogels often compromise their self-healing and sensing performance. Considering this, in this study, we developed a high-strength, recyclable hydrogel with a wide monitoring range, formulated from acrylic acid, hexahydrate aluminum chloride, and polyquaternium-10. By employing a simple freeze-thaw process, the tensile strength of the hydrogel was significantly increased from 0.3 MPa to 1.89 MPa, and the elongation at break was enhanced from 900% to 1400%. Additionally, the hydrogel demonstrates exceptional adhesion to various substrates and possesses mechanical-electrical dual self-healing properties. The hydrogel's broad strain detection range (1%-400%) further underscores its potential for high-performance sensing applications. Furthermore, the reconfigurable, high-density supramolecular network of hydrogels enables the reprocessing of discarded material into value-added products through a straightforward water swelling treatment. We believe that our approach offers a straightforward and efficient strategy for enhancing the mechanical properties of acrylic acid-based hydrogel sensors and, more significantly, contributes to the sustainable utilization of hydrogel materials.","PeriodicalId":405,"journal":{"name":"Polymer","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It will be a waste of resources if these waste HAFs cannot be handled sensibly and efficiently. Based on the above background, in this paper, discarded HAFs are recycled for the preparation of heterocyclic aramid nanofiber aerogel membrane (HANFAM) at greatly reduced cost. The strategy started from the chemical exfoliation of discarded HAFs, which were converted into HANFAM through the bladed coating followed by the freeze-drying techniques. The prepared HANFAMs have tunable and ultra-low dielectric constants and low dielectric loss, with the dielectric constant range of 1.31-1.47 and the dielectric loss range of 0.0026-0.0073 at 1 MHz, which are much lower than other reported aerogel materials. Therefore, it can be used as an important substrate to secure high-speed circuit transmission in integrated electronic devices. In addition, the obtained HANFAMs exhibit a high initial thermal decomposition temperature of 514 °C and a low thermal conductivity of 28.87-40.73 mW/(m·K).

In this study, oriented PA4 fibers were fabricated by dry spinning followed by thermal drawing. Elastic modulus (El) of the crystalline regions (crystal modulus) of PA4 fibers in the direction parallel to the chain axis was evaluated from the X-ray diffraction peak shift owing to the tensile stress. The apparent El value of PA4 is 67 GPa for meridional 004 reflection and 119 GPa for 0010 reflection, respectively. The reason for the different El is that the decrease of crystallite size of PA4 by the applied stress brought extra shifts of 004 reflection peak to lower angle based on the Laue factor. In contrast, 0010 reflection peak received less effects from this effect, and the El value of 119 GPa obtained from 0010 reflection was considered to be a reliable value. The observed El value of PA4 is much lower than the calculated values assuming fully extended planar zigzag skeleton for PA4. Thus the low El value is attributed to the highly contraction (-1.9%) from the fully extended conformation as observed for another polyamides.","PeriodicalId":405,"journal":{"name":"Polymer","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report high-flux polyamide thin-film composite (TFC) membranes consisting of Tröger’s base for nanofiltration. Tröger’s base diamine (TBD) was synthesized as an aqueous phase monomer for interfacial polymerization. Detailed characterization of TBD-based polyamides was performed using thermal, spectroscopic, and microscopic analyses. Notably, the V-shaped and rigid Tröger’s base motif rendered TBD-based polyamide (named TBD-TMC) features with enhanced microporosity as well as an enlarged pore size compared to conventional polyamide chemistry (i.e., MPD-TMC). As a result, the TBD-TMC membrane exhibited a 570% improvement in water permeance compared to MPD-TMC membranes while exhibiting moderate salt rejection up to 91%, outperforming most reported nanofiltration membranes. Also, the TBD-TMC membrane exhibited high monovalent/divalent ion selectivity (∼7.0 for NaCl/Na2SO4 separation), which may have resulted from the combined effects of size exclusion and charge repulsion. This work highlights the potential of Tröger’s base motif as a new diamine monomer for interfacially polymerized membranes to tune their microporous structures.","PeriodicalId":405,"journal":{"name":"Polymer","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic coatings are widely exploited to provide corrosion protection on low-carbon steel. However, the raw materials and preparation methods for common anticorrosive coatings are not sustainable. In this framework, the efficient microwave-assisted methacrylation of a natural polyphenolic compound, tannic acid (TA), provided a UV-curable monomer with a high degree of substitution. The produced methacrylated tannic acid (MTA) was characterized by means of 31P NMR and FTIR spectroscopies. The UV-curing of MTA by radical photopolymerization was deeply investigated via the real-time FTIR, photo-DSC, and photo-rheological analyses, confirming the high photo-reactivity of MTA with a conversion of 80% and a gel point at 2.5 s. The UV-cured MTA showed good thermal stability and a glass transition temperature (Tg) of 133 °C. Furthermore, UV-cured MTA coating exhibited high hardness and hydrophobicity. The zeta potential measurement indicated a negatively charged surface with an isoelectric point (IEP) at pH 2.7. Finally, the good corrosion protection performance of UV-cured MTA coating on plasma pre-treated steel surface was assessed through electrochemical impedance spectroscopy.","PeriodicalId":405,"journal":{"name":"Polymer","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
