The synthetic strategy involved aminolysis of polysuccinimide with <i>N</i>-Boc-1,6-hexanediamine followed by sequential modification with 4-nitro-1,8-naphthalic anhydride and morpholine, yielding a water-compatible fluorescent material. The structure of the obtained polymer was confirmed by ¹H NMR spectroscopy. The sensing behaviour of the polymer toward Fe²⁺ and Fe³⁺ ions was investigated in aqueous solution by fluorescence spectroscopy. Addition of iron ions resulted in a concentration-dependent decrease in emission intensity attributed to fluorescence quenching. Analysis of the quenching process using Stern–Volmer relationships demonstrated efficient interaction of the polymer with both oxidation states of iron, while a more pronounced and rapid response was observed for Fe³⁺ ions. The performance of the material was further evaluated in thin solid films. Fluorescence microscopy revealed substantial emission suppression after exposure to iron ions, consistent with the behaviour observed in solution. Morphological changes induced by polymer–metal interactions were examined by atomic force microscopy, providing complementary information on film structure and surface characteristics.

The plasticizing effect, service life, and application scenarios of polymers were highly dependent on the structure of the plasticizer. Among them, dioctyl terephthalate (DOTP), a widely used commercial plasticizer, achieved a good balance between the performance and service life of plasticized samples due to its overall long-chain molecular structure. However, concerns regarding the potential biotoxicity and environmental persistence of DOTP could not be overlooked. Moreover, its industrial production heavily relies on non‑renewable petrochemical resources, raising concerns over resource depletion, environmental footprint, and long‑term supply security. To address these issues, we herein proposed a novel molecular design strategy that leverages the synergistic effect of “long-chain, epoxy and ester” mobility to achieve both excellent plasticizing efficiency and migration resistance while reducing the reliance on petrochemical resources. Specifically, a series of long-chain epoxy-ester plasticizers were designed and synthesized: epoxidized acetylated ethyl ricinoleate (EAER), epoxidized acetylated n-butyl ricinoleate (EANBR), epoxidized acetylated n-hexyl ricinoleate (EANHR), epoxidized acetylated n-octyl ricinoleate (EANOR), and epoxidized acetylated n-decyl ricinoleate (EANDR). By adjusting the alkyl chain length, the plasticizing effects of these ricinoleate-based plasticizers with different chain lengths on polyvinyl chloride (PVC) were systematically investigated. The results demonstrated that, compared to pure PVC, the optimally plasticized sample, PVC/EANHR20, exhibited an approximately 30-fold increase in notched impact strength (891 J/m), a more than 50-fold improvement in elongation at break (175%), and a 30% reduction in glass transition temperature (<i>T</i>_<i>g</i>). Furthermore, EANHR exhibited excellent migration resistance and thermal stability. Notably, its thermal stability was comparable to that of the commercial plasticizer DOTP.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148987142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal degradation process of polyamide can be changed under different atmospheric conditions.

In triboelectric nanogenerators (TENGs), many cellulose-based triboelectric materials rely on refined nanocellulose, functional additives, or relatively complex fabrication processes, whereas the direct conversion of real paper waste into deliberately surface-engineered tribolayers remains comparatively underexplored. Herein, waste notebook paper is upcycled into surface-patterned cellulose/poly(vinyl alcohol) (CePVA) biocomposite films for high-performance triboelectric nanogenerators (TENGs). Cellulose powder was first extracted from waste notebook paper through alkaline-bleaching treatment and mechanical grinding and then incorporated into a PVA matrix to form flexible biocomposite films. Among the investigated compositions, CePVA70/30 showed a balanced combination of water resistance, mechanical integrity, and processability, with a water absorption of 15.58 ± 2.76%, tensile strength of 3.38 ± 0.45 MPa, elongation at break of 2.09 ± 0.36%, and Young’s modulus of 2.37 ± 0.27 MPa. The optimized composite was mechanically consolidated on a concave polystyrene mold to produce a convex-patterned CePVA film (<i>c</i>-CePVA) with uniform surface microstructures and a water contact angle of approximately 112°. When paired with a convex-patterned PDMS (<i>c</i>-PDMS) tribonegative layer, the resulting waste-paper-derived TENG exhibited improved electrical output compared with the flat counterpart, delivering an open-circuit voltage of 220 V, a short-circuit current of approximately 60 µA, and a maximum instantaneous power density of 39 mW m^{− 2}. The enhanced performance is attributed to the combined effects of cellulose/PVA hydrogen-bonding interactions, balanced mechanical flexibility, and surface-pattern-induced contact-area enhancement. The device also demonstrated capacitor-charging capability, LED operation, and functional output over 20,000 operating cycles. This work integrates real wastepaper valorization with triboelectric interface engineering, providing a practical route for converting discarded notebook paper into value-added biocomposite tribosurfaces for low-frequency mechanical energy harvesting.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 10","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148987117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Representative polymers, including γ-polyglutamic acid, alginate, chitosan, hyaluronic acid, gelatin, cellulose derivatives, dextran, silk fibroin, pullulan, agarose, and chitin, are discussed in terms of their sources, ionic characteristics, degradation behavior, and suitability for injectable hydrogel formation.
