The use of 1-ethyl-3-methylimidazolium acetate ([EMIM][Ac]) as an ionic liquid solvent facilitated the dissolution of cotton, enabling the creation of a spinning dope containing cellulose and polyester fibers. Successful spinning of bicomponent fibers ensued, followed by comprehensive fiber evaluation. The dissolution of cotton was achieved with [EMIM][Ac], and spinning trials were conducted to devise a suitable method for regenerated cellulose. Tensile tests on the produced cellulosic fibers clearly demonstrated an increase in tensile strength with higher cellulose concentration. The introduction of polyester fibers to the spinning dope, comprising [EMIM][Ac] and cotton, posed challenges to the entire spinning process. Tensile tests on the resulting bicomponent fibers revealed a decrease in tensile strength compared to pure regenerated cellulose fibers. This reduction was attributed to increased voids and irregular polyester fiber distribution, corroborated by microscopy images and a wicking test. It was concluded that the quantity and length of polyester fibers significantly influenced the tensile strength of the bicomponent fibers, with lower concentrations and shorter fibers resulting in higher strength.</p>\u0000 </div>","PeriodicalId":7372,"journal":{"name":"Advances in Polymer Technology","volume":"2024 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5239028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141584082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These wood-based biopolymers have garnered significant focus in recent years due to their environmental friendliness and vast potential across many different fields. A full factorial design with three independent variables (layer height, printing speed, and heat treatment exposure time) at three levels was considered. The research explores printing speeds higher than the speed ranges typically investigated in the existing scientific literature on FDM 3D printing of wood-based polymers. Additionally, in this study, heat treatment is proposed as a post-processing operation to enhance certain crucial proprieties such as surface quality, hardness, mechanical strength, and accuracy. The findings reveal that heat treatment has a positive influence on the investigated output parameters. Notably, 3D printed samples subjected to heat treatment exhibit an average decrease of 112.1% in surface roughness for a 5-min exposure time and 121.73% for a 10-min exposure time. The surface hardness of the samples also improved after applying the heat treatment. The part hardness improved with an average of 0.65%. Furthermore, significant correlations were observed between layer height and surface quality, hardness, printing speed, and tensile strength. Notably, printing speed contributed significantly to the variation in tensile strength, accounting for 52.77% of the parameter’s variation. These insights shed light on the optimization of 3D printing processes for wood-based biopolymers, paving the way for enhanced performance and applicability across diverse fields.</p>\u0000 </div>","PeriodicalId":7372,"journal":{"name":"Advances in Polymer Technology","volume":"2024 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/7432507","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141435597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nano-Al₂O₃ particles with different contents are added into the HNBR composites. Then, friction and wear tests are conducted using a pin-on-disk tribometer. Scanning electron microscope (SEM) is used to observe wear topography of the HNBR composite surfaces. Attenuated total reflection–Fourier transform infrared (ATR–FTIR) spectroscopy is used to investigate mechanism of nano-Al₂O₃ reinforcing HNBR. Results show that the filled nano-Al₂O₃ and its contents significantly affect friction and wear performances. Presence of the nano-Al₂O₃ obviously decreases friction coefficient and volume wear rate. Friction coefficient and volume wear rate of the composites reduce initially with the increase of nano-Al₂O₃ content and then increase with further increasing the nano-Al₂O₃ content. The HNBR material filled by the nano-Al₂O₃ with the content of 15 phr shows better antifriction and wear performances. SEM results indicate that the HNBR material filled by the nano-Al₂O₃ of 15 phr presents the best topography of wear surface compared with the HNBR materials filled by other nano-Al₂O₃ contents in this study. ATR–FTIR results show that mechanism of the nano-Al₂O₃ reinforcing HNBR for wear resistance is due to the graft reaction between the modified nano-Al₂O₃ and HNBR to form cross-linking networks around the Al₂O₃ nanoparticles, and self-polymerization of unsaturated groups on the surface of the nano-Al₂O₃ to form interpenetrating polymer networks with the HNBR molecular main chains.</p>\u0000 </div>","PeriodicalId":7372,"journal":{"name":"Advances in Polymer Technology","volume":"2024 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5891303","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141264586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the information provided, there will be a growing demand for bitumen, a key raw material used in the manufacturing of asphalt. Bitumen may account for up to 60% of the total usage in asphalt production. This study aims to determine the effect of different content of polylactic acid (PLA) on the change in the chemical and physical properties of biopolymer bitumen during its modification. This study was carried out by using a sample of petroleum road bitumen from CASPI BITUM (Kazakhstan) and a sample of PLA from Zhejiang Hisun (China). As a part of the research, the change of quality indicators of biopolymer bitumen when adding 4%–10% of PLA to it has been established. The results showed that the values of the average molecular weight and average molar mass increased with increasing the content of PLA in biopolymer bitumen. In particular, when the PLA content in biopolymer bitumen increased up to 10%, the average molecular weight of the biopolymer bitumen increased from 1,263 to 2,759 Mw and the average molar mass increased from 1,215 to 1,395 Mn. It was shown that increasing the PLA content in biopolymer bitumen from 0% to 10% leads to an increase in the softening temperature from 47 to 70°C or ∼ 49%. It was found that all examined samples of biopolymer bitumen are characterized by increased plasticity at 25°C (&gt;100 cm).

Modification of bitumen with a copolymer of ethylene with butyl acrylate and glycidyl methacrylate leads to an improvement in the properties of road bitumen: the softening point, hardness, deformability at low temperatures, elasticity, and adhesion to metal and mineral filler increase. It was shown that ethylene with butyl acrylate and glycidyl methacrylate chemically interacts with the functional groups of bitumen asphaltenes through the epoxy group of glycidyl methacrylate. Analysis of the spectra and group composition indicates an increased content of high molecular weight asphaltenes in the modified bitumen with a slight increase in structuring resins. It has been established that bitumen modified with rubber crumbs of 0.6–1.0 mm in size has high elasticity. The most effective composition of a bitumen-regenerated composite material based on tire reclaim has been determined. In terms of the totality of physicochemical and operational characteristics and comparative cost, the most acceptable is the bitumen-regenerated composition (with a regenerate content of 20%) and is superior in the complex of properties to bitumen modified with an optimal content of ethylene with butyl acrylate and glycidyl methacrylate (1.6%). The technology for modifying bitumen with tire reclaim is less time-consuming, more economically profitable, and environmentally effective, since it utilizes large-tonnage waste of worn-out tires.
