According to UV spectro-scopy data and the results of measurements of the intrinsic viscosity of polymer solutions, it has been found that the introduction of organomineral complexes into the material helps to reduce the extent of photooxidative degradation of the material under conditions of hard UV irradiation. The organomineral complexes used effectively suppress the fouling of the composites by biofilms of the micromycete Yarrowia lipolytica 367-3. The mechanical characteristics of composites containing organomineral additives are maintained at a high level after thermal aging (in accordance with the technical documentation for the material). The composites also meet the technical documentation requirements for weight loss on heating, density, and volume resistivity, but increasing the concentration of the organomineral additive in the composite above 2 wt % leads to an increase in water absorption of the material above required values.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"66 3","pages":"421 - 430"},"PeriodicalIF":1.0,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790377","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 morphological properties of the sample evaluated by employing the field emission scanning electron microscope (FESEM) and the diameters of the samples are between 141 to 234 nm. The presence of both PVA and PAni in the nanofiber structure was evaluated with the aid of Fourier-Transformation Infrared Spectroscopy (FTIR). When a rifampicin-doped PVA film and a rifampicin-doped nanofiber PAni/PVA film were irradiated with a continuous wave laser beam at a wavelength of 532 nm, diffraction ring patterns (DFRPs) were seen. The nonlinear refractive index (NLDX) ({{n}_{2}}), was determined from the number of observed rings. Large value obtained of the order of 212.48 × l0–8 cm2/W for PAni/PVA nanofiber composites. The change in the nonlinear refractive index (Delta n), depends primarily on both the natural refractive index of the material and the NLDX, in which diffraction patterns play a major role in this change. In addition to that, the optical limiting) ({text{OPT}}) (qualities were investigated. Within a solid PAni/PVA host, the dye shows of some impressive optical limiting features.

Hence, solutions of CA and CA/SiO2 were made by acetone/dimethylacetamide (2 : 1) with oxygen enriching and Helium gas. The nanofiber’s morphology and chemical structures were studied by SEM and FTIR, respectively. Finally, the media’s thermal conductivities were calculated using the two-plate Togmeter device test method based on BS 4745:2005, and the media’s tensile strength features were evaluated under the ASTM D638-10 standard. According to SEM images, SiO2 nanoparticles incredibly covered the whole surfaces of CA nanofibers in the CA/SiO2 medium in a cloud shape. FTIR vibration spectrums confirmed the siloxane bands vibrated at 475/75 cm–1 in the CA/SiO2 mat. Moreover, the thermal conductivity of the CA and CA/SiO2 sheets were 0.1 W/(m K) with 0.225 ± 0.005 mm thickness and 0.044 W/(m K) with 0.461 ± 2.88 mm thickness, respectively. Additionally, the CA medium had 0.5 ± 0.28 MPa tensile stress at 2.57 ± 1.25% tensile strain and the CA/SiO2 membrane had 0.561 ± 0.057 MPa at 1.81 ± 0.939%. Hence, the CA/SiO2 nanocomposite medium has a super low thermal conductivity with good mechanical properties. Therefore, the characterization of the thermal conductivity of cellulose Acetate/nano-SiO2 electrospun nanofiber composites for energy-saving, using an Oxygen-enriched method was completely successful.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"66 3","pages":"411 - 420"},"PeriodicalIF":1.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790348","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 influence of chemical nature of hydrophobic comonomer and the copolymer composition on physico-chemical properties of polymers and their ability to strengthen friable (bulk) materials like quartz sand, clay, or limestone was systematically studied. It is shown that synthesized copolymers have relatively low glass transition temperatures, form aggregatively stable molecular solutions in water in a wide range of pH values, and have a pronounced surface activity, while their dried films demonstrate water-repellent properties. It is found that amphiphilic copolymers with a small content of hydrophobic comonomer units are much more effective as stabilizers of soils (bulk materials) in terms of mechanical strength and durability than the original hydrophilic homopolymer.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"66 3","pages":"363 - 375"},"PeriodicalIF":1.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790375","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}
