However, achieving foamed resins with high solids content and low viscosity in order to reduce cost and increase efficiency has been a challenge. A compound aliphatic waterborne polyurethane (AWPU) with high solids content and low viscosity was prepared by pre-polymerization method. The results showed that R value (-NCO/OH molar ratio), D value (hydrophilic group content), A-95 M ratio and IPDI/HDI molar ratio were critical in achieving the characteristics of high solids content and low viscosity of the resins through the synergistic effects of size, particle size distribution, and “electric double-layer”, respectively, and the corresponding resins also had a satisfactory foaming ratio. When <em>R</em> = 2.0, D = 2.8 wt%, A-95 = 0.5 wt%, IPDI/HDI = 5:5, the prepared AWPU resins had good appearance and stability, the solids content could reach 53.5 %, the viscosity is only 175 mPa·s. And the foaming ratio of AWPU-H foamed resins could reach 3.04 (CaCO<sub>3</sub> powder as a filler could reach 2.67), and the foamed layers holes formed are continuous, uniform, and non-collapsing. In terms of application performance, the air permeability and water vapor permeability of the prepared AWPU-H foamed leather could reach 187.32 mm/s and 277.88 g/m<sup>2</sup>·h, respectively.

Graphene modified vinyl ester resin, a new and highly promising composite coating with excellent anti-corrosion, has been widely used in important advance marine equipment. However, their inherent thermosetting cross-linked structures, coupled with the formation of pores and cracks during the curing process, limit their ability to self-heal after mechanical damage, thereby compromising their barrier effectiveness. To address these challenges, this work reports the development of a novel disulfide bond-containing vinyl ester resin by reacting epoxy resin with dithiodipropionic acid. The optimized cured resin exhibits a tensile strength of 50.41 MPa, demonstrates stress relaxation behavior, and possesses physical recyclability at 160 °C under 15 MPa within 30 min, along with heat-induced shape memory properties. Incorporating modified graphene oxide particles into the resin matrix imparts multi-stimuli-responsive self-healing capabilities and introduces a “maze” effect that enhances the coating's protective performance.

For the construction of the polymer structure, a quinoxaline (QX) moiety was utilized as a weak electron acceptor and conjugated with two triphenylamine (TPA) donors to form a new diamine monomer. This monomer was then polycondensed with three dicarboxylic acids to obtain a series of polyamides (PAs), named TPAQ-CA, TPAQ-OA, and TPAQ-SA. TPAQ-CA exhibits green color in the oxidized state, which achieves an optical contrast ratio of 80 % in the near-infrared range with short switching times of 2.9/1.5 s and maintains 80 % of the original optical contrast ratio after 2200 cycles. Owing to the distinct electrochromism from yellow to green, a self-adaptive camouflage model has also been developed for demonstration. Meanwhile, TPAQ-CA displays photoluminescence (PL) performance and aggregation-induced emission enhancement (AIEE) in the solid state, and it is responsive to explosives and HCl gas. Overall, this work highlights the great potential of these PAs for applications in camouflage and PL detection.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"205 ","pages":"Article 109288"},"PeriodicalIF":6.5,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143785758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
