In this study, two silsesquioxane-based fluorescent hybrid porous polymers with semiconducting properties, PCS–PSP and PCS–PSSP, were synthesized by the Friedel–Crafts reaction of octavinylsilsesquioxane with 4,4′-thiene-2,5-diyldibenzonitrile (PSP) and 4,4′-(2,2′-bithiophene-5,5′-diyl)dibenzonitrile (PSSP). The study focused on their physicochemical characterization and photocatalytic activity. Compared with PCS–PSSP, PCS–PSP showed higher thermal decomposition temperature (<i>T</i>_5% = 385 °C), larger specific surface area (1001 m² g^–1), greater pore volume (0.75 cm³ g^–1), more substantial light absorption capacity (250–561 nm), and smaller optical band gap (<i>E</i>_g = 2.21 eV). Their photocatalytic ability was carried out to degrade tetracycline (TH) under visible light, and PCS–PSP exhibited a superior performance with 51% of TH adsorption in the dark and 84% removal efficiency after 1 h of light irradiation. Meanwhile, it also has excellent stability and recyclability. Free-radical trapping experiments and electron spin resonance tests revealed that superoxide radicals (^•O₂^–) played a significant role in the photocatalytic degradation process. Surprisingly, PCS–PSP also can be used as a probe for TH detection with high sensitivity and selectivity.

A critical component in the VPP printing process is photoinitiators (PIs), which trigger polymerization by generating free radicals under light exposure. However, many PIs face challenges due to poor water solubility, leading to issues such as uneven printing, particularly in tissue engineering applications. This review offers a concise yet comprehensive overview of strategies to enhance the water solubility of PIs and their applications in VPP-based 3D printing.

Biobased plasticizers that are biocompatible, nontoxic, and biorenewable have captured much attention as a sustainable alternative to the conventional phthalate for PVC plasticization. Epoxidized cottonseed oil (ECSO), derived as a byproduct of the cotton fiber industry, was synthesized through a safer and more selective solvent-free chemoenzymatic epoxidation reaction of cottonseed oil (CSO) using Novozym 435. The epoxidation reaction products were studied by ¹H NMR, FTIR, and acid number titration, and a varying amount of purified ECSO (0–100 phr) was incorporated into PVC films through solvent casting. The effects of ECSO on the glass transition temperature (<i>T</i>_g), thermal stability, and mechanical properties of the films were examined. The average Young’s modulus dropped up to 330-fold from 1.78 GPa to 5.27 MPa, and the average elongation at break increased up to 80-fold from 3% to 266%. The <i>T</i>_gs decreased from 85.3 °C to the lowest of −25.6 °C, which is well below room temperature and consistent with the flexible and rubbery behaviors. In contrast, unmodified CSO was unable to provide effective plasticization, and a <i>T</i>_g of 76 °C was seen on the second differential scanning calorimetry (DSC) heating. The degradation onset temperature showed an up to 21 °C improvement for ECSO plasticized PVC film, whereas the incorporation of unmodified CSO reduced it. XRD analysis indicated that both CSO and ECSO were initially mixed with PVC chains at a molecular level before heating and emphasized the role of epoxy in the effective plasticization and stabilization of PVC, where intimate mixing alone was insufficient. The findings from this study demonstrate the feasibility and scalability of producing ECSO using sustainable chemoenzymatic epoxidation and provide critical insights into its working mechanisms as an effective bioplasticizer.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 7","pages":"4427–4435 4427–4435"},"PeriodicalIF":4.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814420","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, a stretchable and temperature-tolerant TENG with poly(vinyl alcohol) (PVA)-gelatin-LiCl organohydrogel (PGL–OHG) as the electrode is presented. The PVA-gelatin dual-network structure endows the PGL–OHG with exceptional stretchability (530% fracture elongation and 0.3 MPa tensile stress), while the synergistic effect of dimethyl sulfoxide (DMSO) and LiCl suppresses ice crystallization, thereby extending the operational temperature range to −50 to 50 °C. Moreover, LiCl enhances the ionic conductivity of the PGL–OHG, which ensures the stable electrical output of PGL–OHG TENG. Furthermore, the assembled stretchable PGL–OHG TENG has an outstanding 78 V output voltage, wide working temperature range (−50 to 50 °C), excellent stretchability (250%), durable long-term stability (50 days), and cycling stability (7800 cycles). Additionally, the application of the proposed PGL–OHG TENG in energy harvesting and self-powered devices also exhibits a potential capability in wearable electronics.
