Polyethylene terephthalate (PET) is the most used fiber material, but its hydrophilic property is weak. Common hydrophilic treatment process on PET clothes has lots of defects such as poor washability and undurablity. In this paper, long-chain monomers were introduced into PET main chains to improve its elastic property to promote the diffusion of water molecules. In addition, modified nano-SiO2 particles were also added into PET matrix to improve its hydrophilicity. PET-co-PEA/SiO2 was synthesized by direct esterification with terephthalic acid (PTA), ethylene glycol (EG), polyethylene glycol adipate (PEA), and SiO2 modified by KH560 on the surface. Morphology, structure, thermal property, and hydrophilicity of PET-co-PEA/SiO2 were investigated. PET-co-PEA/SiO2 has a typical PET characteristic absorption peak in FTIR spectra, indicating that the addition of SiO2 has little effect on PET chemical structure. PET-co-PEA/SiO2 shows similar thermal stability as PET, which is weaker than PET/SiO2 but superior to PET-co-PEA. Both nano-SiO2 particles and the copolymerized long-chain PEA can improve the hydrophilicity of PET. Contact angle of PET-co-PEA/SiO2 is 69.56°, which is much lower than that of neat PET 108.5°. © Springer Nature Singapore Pte Ltd. 2019.

The green nanocomposites of poly(lactic acid) (PLA) with various spherical nanocellulose formates (SCNFs) contents were prepared by solution casting method. It is found that the SCNFs act as an effective nucleation agent for crystallization of PLA. A study of the isothermal crystallization kinetics further illustrated that overall crystallization rate of PLA in the nanocomposites was faster than that of neat PLA. Furthermore, the tensile strength and Young' modulus increased by 130% and 116% for the nanocomposites with 10% SCNFs (mass fraction) compared to the neat PLA, respectively.

作者： Dhilip kumar Chinnalagu Balaji Murugesan Krithikapriya Chinniah Selvanathan Ganesan Yurong Cai Sundrarajan Mahalingam Advanced Green Chemistry Lab Department of Industrial Chemistry School of Chemical Sciences Alagappa University Karaikudi 630 003 Tamil Nadu India The Key Laboratory of Advanced Textile Materials and Manufacturing Technology of Ministry of Education National Engineering Lab for Textile Fiber Materials Science and Engineering Zhejiang Sci-Tech University Hangzhou 310018 China AVC College of Arts and Sciences Mannampandal Mayiladuthurai 609 305 Tamil Nadu India

This research paper delves that, two-dimensional (2D) materials such as borophene with its unique layered structure have become a central focus in research and particularly significant for advancing supercapacitor applications. Nevertheless, drawbacks like an uncontrolled self-restacking process decrease its capacitance performance by limiting electrolyte ions diffusion. Herein, zero-dimensional (0D) carbon spheres doped with S and N heteroatoms (LCCS-1) were utilized to intercalate Bphene to obtain LCCS-1/Bphene-0.5 NCs. The liquid phase exfoliation (LPE) technique was used to generate Bphene sheets in a 7:3 ratio of isopropanol and water. The ultrasonically assembled LCCS-1/Bphene-0.5 NCs showcased an improved specific surface area of 2100 m 2 g -1 , which is comparatively higher than the LCCS-1/Bphene-1 NCs combination. Electrochemical performance of the LCCS-1/Bphene-0.5 NCs in 2M KOH electrolyte showcased C s1 = 833 Fg -1 and C s2 = 653 Fg -1 from the CV and GCD evaluations. Moreover, capacitance and diffusion contribution (%) were calculated as 49.8 and 50.2 % at a low scan rate (10 mVs −1 ) from Trasatti and Dunn's method. The assembled LCCS-1/Bphene-0.5//LCCS-1/Bphene-0.5 SSD managed to reach an optimal operating voltage of 2.0 V with an estimated specific energy and specific power value of 30.5 Wh/kg and 10 kW/kg. The LCCS-1/Bphene-0.5//LCCS-1/Bphene-0.5 demonstrated outstanding performance, achieving a capacitance retention of 86.4 % and a coulombic efficiency of 100.1 % after 10,000 charge-discharge cycles. In a nutshell, this study presents a fast and efficient method for synthesizing LCCS-1 NCs integrated with 2D borophene, paving the way for significant advancements in electrode development for supercapacitor applications.

Recent research advances on fabric dyeing have focused on modeling the relationship between dye concentrations and the final color on fabrics. The emerging techniques in related studies have great potential to evolve the traditional dyeing industry to manufacture much more smartly. Given that dyeing is a complex process regulated by many factors, one of the challenging problems in the aforementioned techniques is to maintain the modeling accuracy at acceptable level. Other than developing high-performance algorithms and model architectures, it is also important to include effective data pre-processing techniques in modeling. In this paper, we show that conducting log-Transform to the industrial dyeing data can greatly improve the performance of industrial dyeing recipe models. Such observations are confirmed on modeling tasks using different formats of color as input and different types of loss function in the model training. These findings may provide useful implications for related studies for the dyeing industry. © 2023 The authors and IOS Press.
