In this work, attapulgite (ATP) was used as the adsorption carrier of inorganic pigments to prepare color-dyed attapulgite (CD-ATP). The selected environmentally friendly inorganic pigments were well adsorbed by ATP in KOH aqueous solution, and could stably be monodispersed in KOH aqueous solution for more than 168 h. Moreover, the KOH aqueous solution could be reused repeatedly, thereby, a sustainable method to prepare novel CD-ATP was realized. By blending the as-prepared CD-ATP with polyamide-6 (PA6), a series of dope-dyed colorful PA6 composites was prepared. Scanning electron microscope (SEM) results indicated that the CD-ATP was still monodispersed in the PA6 matrix, and endowed PA6 with a vivid color. Further studies show that the adding of CD-ATP had little influence on the properties of PA6, but significantly reduced the water adsorption. This novel color-dyed ATP has potential implications in making paper-making blankets and is highly expected to have more extensive applications in many fields of life.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 48","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microscopic images confirmed that the GO nanoplatelets are mainly localized in PBAT phase and then at the interface, contrary to the thermodynamic affinity of GO toward EVOH. The reactive nature of PBAT/EVOH/GO nanocomposites was confirmed via time-sweep rheological studies where specific changes were observed in melt viscosity over time. The results of microscopic studies, rheometry, tensile test, and dynamic mechanical thermal analysis (DMTA) confirmed that localizing GO at the interface establishes strong interactions between PBAT and EVOH. By the addition of 0.75 wt% GO, tensile and yield strength were improved by 19% and 45%, respectively. Increasing GO significantly increased the hydrolysis degradation rate of the nanocomposites.

In our study, butylated hydroxy toluene (BHT), ascorbic acid and α-tocopherol, which are considered synthetic standard antioxidants, were used to compare antioxidant activity. In addition, since it is known that the MDA levels resulting from the oxidation of fats in Saccharomyces cerevisiae yeast cells are inversely proportional to the antioxidant properties, it gave an idea about the in vitro antioxidant properties of the new synthesized PCs.

The electrode/electrolyte interface interaction is one of the most important factors in improving the electrochemical performance of energy storage materials, and these polymers are often combined with a negatively charged poly(styrene sulfonate) (PSS) chain to improve their interaction with alkali metal cations such as sodium and potassium. In this work, we performed a one-step electrochemical synthesis of PEDOT on carbon fabric using the molecule 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) to create highly effective materials for supercapacitor electrodes. The electrode had a significant increase in capacitance value, measured 16.4 times higher than that of the PEDOT electrode. The 2-electrode system exhibited a specific capacitance value of 495.2 F g−1 at a scan rate of 5 mV s−1. It exhibited a high operating voltage of 2.3 V in aqueous electrolyte system. It showed a significant energy density of 109.0 Wh kg−1 when operating at 6.1 kW kg−1 power density and 85.2 Wh kg−1 when operating at 30.6 kW kg−1 power density. Recent findings reveal that the capacitance retention performance value of the device increased significantly to 113.9% after 25,000 cycles in 3.0 M NaCl aqueous electrolyte, demonstrating its outstanding long-term durability. Thus, the creation of the synthesized supercapacitor electrode is a significant advance in the study of conducting polymers, which often have a limited lifetime in real-world electronic applications.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"141 48","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to enhance the rejection of heavy metal ions, a critical issue in water treatment. The parameters of the interfacial polymerization (IP) process, including monomer concentration, reaction time, curing temperature, and curing duration, were tailored to determine the most effective membrane configuration. Polyimide (P84) was employed as the support material, with the IP involving trimesoyl chloride (TMC) and piperazine (PIP). Comprehensive characterization through Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), and water contact angle measurements provided information on the functional groups, surface and cross-sectional morphologies, and hydrophilic properties of the membranes. The optimized fabrication conditions, involving 0.2 w/v% TMC and 2.0 w/v% PIP monomer concentrations, a 2-minute IP reaction time, and a 40°C curing temperature for 10 minutes, led to the membranes achieving arsenic and chromium rejections of 89.7% and 99%, respectively. This was accomplished while maintaining a high pure water permeability of approximately 16.9 Lm−2h−1bar−1.

PTBI displayed commendable thermal stability, as evidenced by a temperature of 475°C at which a 5% weight loss occurred and a char yield of up to 65% at 800°C. Trinitrotoluene (TNT) was effectively adsorbed by PTBI in aqueous solutions, thanks to the combined effects of three π–π interactions and one dipole–π interaction. At 25°C, PTBI achieved a maximum adsorption capacity as high as 280.8 mg/g, with approximately 60% of this capacity attained within just 1 h. Furthermore, a thermodynamic analysis showed that the adsorption of TNT by PTBI was a spontaneous, exothermic process that was followed by a decrease in entropy. It is noteworthy that following five adsorption and desorption cycles, the adsorption efficiency held steady at a relatively high level using acetone as the eluent.

The phase composition and microstructure of the samples were analyzed by scanning electron microscope, energy-dispersive x-ray spectroscopy, x-ray diffraction.

Moreover, the density and hardness of sample S3 showed minimal variation compared to those of unmodified sample S1.

This paper reported a novel observation of cold crystallization (CC) and the key factors affecting the formation of CC in the PEEK membrane via immersion precipitation phase separation, using mixture solvents of concentrated sulfuric acid (SA) and methane sulfonic acid (MSA). The CC in PEEK was identified by an exothermal peak slightly above the PEEK's glass transition temperature (Tg) at 146–150°C in differential scanning calorimetry (DSC). The CC formation was contributed to folded rigid segments resulted from the solid–liquid phase separation. Factors affecting CC investigated in the membrane preparation were the exposure time before immersion and the solvent ratio. It was found that increased exposure time from 0 min to 15 min in ambient led to cellular pore structure with decreased total crystallinity (28.9%–25.5%), but increased proportion of CC (27.7%–43.6%) for PEEK3:1 membrane. Increase of SA in the mixture solvent resulted in decreased CC and total degree of crystallization. Tensile strength measurements demonstrated that the CC contributed positively the strain of PEEK membranes.
