However, their widespread use generates significant quantities of waste, which poses serious environmental and disposal challenges. In this study, rigid PU foam was effectively depolymerized <i>via</i> microwave-assisted glycolysis, using 2-methyl-1,3-propanediol (MP-diol) as the glycolysis agent and sodium hydroxide (NaOH) as the catalyst. The depolymerization process was systematically optimized by varying the reactant ratio, catalyst concentration, reaction temperature, and microwave power. The resulting oligomeric product (PUF-O) was characterized by physical, chemical, and spectroscopic analyses. Subsequently, a series of polyester polyols (PEs) was synthesized by partially and fully replacing neopentyl glycol with an oligomeric product in formulations containing adipic acid and phthalic anhydride. These PEs further reacted with commercial polyisocyanates to form polyurethane coatings. Characterisation was conducted to analyse the optical, mechanical, chemical, and anticorrosive properties of the cured films were characterized. The PUF-O-based polyols exhibited performance comparable to those synthesized using conventional raw materials, demonstrating the feasibility of incorporating recycled PU foam into high-performance coating systems.

In this architecture, a non-conjugated node, typically an imide nitrogen, breaks conjugation between the donor and acceptor, spatially separating the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) on the two components. This decoupling renders p- and n-type doping independent and precisely controllable, thereby overcoming the fundamental limitations of conventional conjugated polymers. This review systematically summarizes the recent progress in D-n-A systems from small molecules to functional polymers. In PBI dyads and triads, node-induced exciton coupling enables tunable photophysics, whereas molecular conformation controls the competition between fluorescence and symmetry-breaking charge separation. The cascade energy-level alignment in the D-n-A₁-n-A₂ architectures yields long-lived charge-separated states by spatially separating the radical ion pair. Covalent linking of stable radicals (TEMPO, TTM) to PBI or naphthalene bisimide (NBI) <i>via</i> nodes allows efficient photoinduced intersystem crossing and the formation of quartet states (S=3/2), promising for molecular qubits. In the polymer domain, D-n-A polymers with a small fraction of PBI acceptors exhibit photoenhanced hole transportation, serving as hole-transporting layers for photodetectors. Bipolar polymers with a D:A ratio of approximately 1:1 demonstrate ambipolar charge transport and storage and have been successfully applied in flexible supercapacitors, lithium-ion batteries, and multicolor electrochromic devices. Finally, the outlook highlights future directions: precise control of donor-acceptor coupling, optimization of polymer morphology, translation to stable solid-state systems, and multifunctional integration of electrochemistry with spin quantum properties.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 11","pages":"3623 - 3638"},"PeriodicalIF":4.6,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149339218","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}

This study compares the efficacy of mechanical mixing versus <i>in situ</i> polycondensation as methods for incorporating Fe₂O₃ and Al₂O₃ nanocrystalline particles into PI matrices with varying flexibility of macrochains that have different dianhydride fragments based on either pyromellitic acid (PMDA) or 1,3-bis(3′,4-dicarboxyphenoxy)benzene acid (R), with the same diamine: 4,4′-oxydianiline (ODA). Comprehensive characterisation using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed the chemical and crystalline structures of the polymers and the inorganic fillers, respectively. Scanning electron microscopy (SEM) analysis demonstrated that the <i>in situ</i> method provided significantly more homogeneous particle distribution within the matrix, reducing the agglomeration observed with mechanical mixing. This facilitated adding more filler into the PIs, which in turn enhanced key properties of the materials. For example, a semi-flexible-chain PMDA-ODA-based composite with 7 wt% of Fe₂O₃ prepared <i>in situ</i> exhibited a 19% increase in rigidity relative to the host polymer. In contrast, the mechanically mixed counterpart demonstrated only a 6% increase in Young’s modulus relative to the matrix. Meanwhile, the tensile strength of the <i>in situ</i> prepared composite is approximately the same as that of the corresponding matrix polymer, whereas for the mechanically mixed composite it decreases by about 20%. For Al₂O₃-containing composites, materials based on the flexible-chain R-ODA exhibit higher thermal stability than those based on the semi-flexible PMDA-ODA, which is attributed to better accommodation of local inhomogenieties and more efficient heat dissipation.
