These polymers have Mw 35524–12852 in moderate yields (35–67%). The influence of this kind of polymer’s structures on the optical properties was studied in detail with 1H NMR,13C NMR, FTIR, UV, FL, CV, TGA, and fluorescence lifetime test. The results showed that these polymers exhibited good solubility, high thermal stabilities, high oxidative stability, stable optical properties and emitted variously colored fluorescence in moderate quantum yields (28–61%) due to their different energy gap. The fluorescence lifetimes of the polymers P1, P2, P3, and P4 were 0.8974, 1.695, 1.728, and 0.5929 ns, respectively. And the values of lifetime decrease with increasing solvent polarity. The effective light-emitting color regulation of poly(aryleneethynylene)s was realized by Gaussian calculation and experiment results.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141511203","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 kinetic parameters and curing temperature of the curing reaction of the epoxy resin/ nano rare earth oxides system were calculated by Kissinger–Ozawa, Crane method and T-β extrapolation method. The results showed that the rare earth compounds reduced the activation energy of the epoxy resin curing reaction, but did not change the curing mechanism of the epoxy resin. Studies on the influence of sample fracture morphology showed that the introduction of nano rare earth compounds plays an important role in improving the tensile properties of nanocomposites. When the 1% weight component of nano Gd2O3 was added to the composite, the tensile strength of the composite increased by 65.18%, the flexural strength and modulus increased by 57.92 and 70.04%, respectively, and the glass transition temperature increased by 17.55°C.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141511112","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 apparent morphology of the porous membrane was observed by scanning electron microscopy, and the hydrophobic properties of the porous membrane were investigated before and after the infilling of the silicone oil by contact angle tester. The results show that the hydrophobicity of the porous substrate prepared when the content of TiO2/SiO2 particles is 15% and the concentration of composite material is 20 mg/mL is the best, and the sliding angle of the oil-filled SLIPS is 2° at the minimum.

It has been shown that systems based on these metal complexes, carbon tetrachloride, and isopropylamine as a reducing agent are capable of initiating the radical polymerization of methyl methacrylate. The most effective among those studied are systems based on ruthenacarboranes containing 9,9-dimethyl-4,5-bis-(diphenylphosphino)xanthene as a ligand. These compounds are capable of carrying out the process in a controlled manner, as evidenced by a linear increase in the molecular weight of the polymer and a decrease in dispersity values with increasing conversion. The controlled process according to the ATRP mechanism is confirmed by the presence of chlorine atoms at the ends of the polymer chains, as it has been detected by MALDI mass spectrometry. It has been shown that the possibility of coordination of the ruthenium atom with the oxygen atom of the ligand reduces the rate of the polymerization process and the degree of control over it.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141192033","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}
