At the first stage, the titanium dioxide nanoparticles surface has been modified with triethoxyvinylsilane. The so introduced surface vinyl groups of the titanium dioxide‒triethoxyvinylsilane nanoparticles have been used to graft poly(acrylic acid). To do so, free-radical polymerization of acrylic acid in the presence of the titanium dioxide‒triethoxyvinylsilane nanoparticles has been performed at the second stage. Molecular parameters of the obtained titanium dioxide‒triethoxyvinylsilane‒poly(acrylic acid) nanoparticles have been determined by means of static and dynamic light scattering, and their structure has been confirmed by means of infrared spectroscopy.

Effect of various experimental variables such as dye concentration, pH, contact time duration, and temperature were investigated. The grafted Kosa silk fabric was then subjected to exhaust dyeing with Acid Blue 25. The color properties of the dyed fabric were analyzed in terms of CIE L*, a*, and b* values (where L represents the difference in lightness/darkness, a denotes the difference in redness/greenness, and b refers to the difference in yellowness/blueness) and K/S values.

The one-stage method for producing composites involves the formation of filler structures during the burning of low-temperature plasma in the bulk of an aqueous polymer solution. Electrode materials were used as precursors. Regardless of the production method, 2D hexagonal structures are formed and embedded in the polymer matrix. This is evidenced by IR spectroscopy data showing shifts in the main characteristic bands and the appearance of new ones. It has been established that layered fillers can be both plasticizers and reinforcing agents. The influence of the viscosity of the polymer matrix on the mechanical characteristics of the composites has been revealed. The introduction of fillers changes the surface roughness, leading to an increase in hydrophobicity of the composites. It has been established that the current–voltage curves of the composites are nonlinear, so that such composites can be considered as flexible analogues of nonlinear electronic components.","PeriodicalId":739,"journal":{"name":"Polymer Science, Series B","volume":"65 5","pages":"692 - 699"},"PeriodicalIF":1.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139411007","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}

Then, the raw rubber, carbon black, vulcanizing agent, and so forth were mixed and then vulcanized, and the performance of the product was tested. The results showed that the synthesized acrylic rubber contained low levels of ash and volatile matter. The structure of the acrylic rubber was consistent with its design, and the glass transition temperature was –28.1°C. A study showed that the product vulcanized quickly. When the dosage of butyl acrylate was increased, the tensile strength decreased, and the elongation at break increased. The working temperature was reduced by adding plasticizer. With increasing plasticizer (RS-735) content, the elongation at break increased, and the tensile strength decreased. When the RS-735 level reached 10 phr, the brittleness temperature of the product decreased to –28°C.

The gallic acid-polyethylene imine codeposited carbon fibers were used to fabricate epoxy matrix composites. The results of mechanical tests showed that interlaminar shear strength, flexural modulus and strength of the gallic acid-polyethylene imine codeposited carbon fiber composite were increased by 27, 38, and 27% respectively, compared with those of the untreated carbon fiber composite.
