Synergistic effect of GMA and TMPTA as co-agent to adjust the branching structure of PLLA during UV-induced reactive extrusion J. Polym. Eng. (IF 2.0) Pub Date : 2023-07-04 Xi Chen, Wei-Tao Huang, Bing-Yu Yuan, Guang-Jian He, Xiao-Chun Yin, Xian-Wu Cao
In this work, glycidyl methacrylate (GMA) and trimethylol propanetriacrylate (TMPTA) are employed to adjust the branching structure of poly L-lactide acid (PLLA) during reactive extrusion induced by UV irradiation. The reaction of GMA epoxide with terminal carboxyl or hydroxyl groups at PLLA chain end can introduce C=C groups onto PLLA molecular chains. Chain branching reaction occurred via the free-radical

Fabrication and characterization of microencapsulated dimethyl adipate phase change material with melamine-formaldehyde shell for cold thermal energy storage in coating J. Polym. Eng. (IF 2.0) Pub Date : 2023-06-28 Bhagyashree Vasantrao Waghmare, Prakash A. Mahanwar
Microencapsulated phase change material (MPCM) was synthesized by using the in-situ polymerization technique. Dimethyl adipate (DMA) and melamine-formaldehyde were used as core and shell material for polymerization respectively. Sodium laureate sulphate (SLS) is used as a surfactant. The thermal properties were characterized by using a differential scanning calorimeter (DSC) and thermogravimetry analysis

Electrospinning and electrospun based polyvinyl alcohol nanofibers utilized as filters and sensors in the real world J. Polym. Eng. (IF 2.0) Pub Date : 2023-06-26 Kamran-ul-Haq Khan, Suhaib Masroor, Ghaus Rizvi
Electrospinning is a contemporary and effective technique for producing fine fibers with diameters as small as nanometers by using an electric field. These fibers have numerous industrial applications, including filtration, sensors, composite materials, and membranes. This study provides an overview of the electrospinning process and discusses a few applications of polyvinyl alcohol based electrospun

PVA-borax/g-C3N4 nanocomposite hydrogel with excellent mechanical property and self-healing efficiency J. Polym. Eng. (IF 2.0) Pub Date : 2023-06-19 Shishan Xue, Dengliang He, Xianchun Hu, Yuqian Cao, Jinliang Ge, Shuxin Liu
Most self-healing hydrogels always exhibited poor mechanical property which largely limited the applications in many fields. In this work, g-C3N4 nanosheets were introduced to the PVA-borax hydrogel to reinforce the network without sacrificing the self-healing ability. The obtained hydrogel displayed remarkable tensile strength (0.98 MPa), Young’s modulus (1.54 MPa) and toughness (4.43 MJ m−3), of

The efficient removal of low concentration hexavalent chromium via combining charged microporous membrane and micellar adsorption filtration J. Polym. Eng. (IF 2.0) Pub Date : 2023-06-15 Wu-Shang Yang, Peng Zhang, Shu-Yang Shen, Qian-Wei Su, Ya-Ni Jiang, Jian-Li Wang, Ming-Yong Zhou, Ze-Lin Qiu, Bao-Ku Zhu
It is challenging to effectively purge wastewater containing heavy metal ions at low concentration. In order to remove trace Cr (VI) from wastewater efficiently, a positively charged microporous membrane was prepared by firstly non-solvent induced phase separation (NIPS) of amphiphilic polymer and secondly surface quaternization modification. The morphologies, surface roughness, surface charge, hydrophilicity

The degradation behaviors of optical cellulose triacetate films in alkali/acid solutions J. Polym. Eng. (IF 2.0) Pub Date : 2023-06-13 Jian’an Wang, Xiushan Fan
In this research, the degradation behaviors of ramie-based cellulose triacetate (CTA) films in alkali or acid solutions at room temperature were assessed. Moreover, the attenuated total reflection infrared (ATR-IR), physicochemical properties testing, scanning electron microscope (SEM), and thermogravimetric analysis/differential scanning calorimeter (TG/DSC) were employed to evaluate the detailed
