The current work describes room-temperature gas sensing performances using an oligoacenaphthylene (OAN)/p-hydroxyphenylacetic acid (p-HPA) composite. Based on inverse gas chromatography (IGC), the London dispersive surface energy γ s d is calculated by using 14 representative models. Even when the γ s d values of both OAN and the OAN/p-HPA composite are decreased as the temperature increases, the surface of OAN shows a higher value than that of the composite. The Gibbs surface free energy values of both are decreased with an increasing temperature. In our results, higher Lewis basic characters are observed in OAN and the OAN/p-HPA composite and the OAN/p-HPA surface exhibits a higher basicity compared to OAN. Because of the presence of phenolic groups in the OAN/p-HPA composite, the more important basic character drives a significant CO gas sensing ability with a sensitivity of 8.96% and good cycling stability as compared to the pristine counterparts. It is expected that the current study sheds light on a new pathway to exploring polymer composite materials for futuristic diverse and multiple applications, including IGC and gas sensor applications.

“…Benzoyl peroxide (BPO), a versatile substance, has attracted increasing attention, and has been widely employed as an organic initiator, oxidant agent, antibacterial agent, and bleaching agent in industrial production, pharmaceutical formulations, and the food industry [1,2,3,4,5]. However, BPO equipped with strong electron-withdrawing groups is water-insoluble, which makes it a potential environmental contaminant and could be a threat to human health due to the toxicity of peroxide and its various decomposition products (such as benzoic acid, benzoic acid ester, and biphenyl) [6].…”

The method capable of rapid and sensitive detection of benzoyl peroxide (BPO) is necessary and receiving increasing attention. In consideration of the vast signal amplification of fluorescent conjugated polymers (FCPs) for high sensitivity detection and the potential applications of boron-containing materials in the emerging sensing fields, the organoboron FCPs, poly (3-aminophenyl boronic acid) (PABA) is directly synthesized via free-radical polymerization reaction by using the commercially available 3-aminophenyl boronic acid (ABA) as the functional monomer and ammonium persulfate as the initiator. PABA is employed as a fluorescence sensor for sensing of trace BPO based on the formation of charge-transfer complexes between PABA and BPO. The fluorescence emission intensity of PABA demonstrates a negative correlation with the concentration of BPO. And a linear range of 8.26 × 10−9 M–8.26 × 10–4 M and a limit of detection of 1.06 × 10–9 M as well as a good recovery (86.25%–111.38%) of BPO in spiked real samples (wheat flour and antimicrobial agent) are obtained. The proposed sensor provides a promising prospective candidate for the rapid detection and surveillance of BPO.

“…For this reason, plasma technologies [39] (corona [40], glow [41], photo-grafting, UV induced and graft polymerization [42,43]) have been used to modify the surface of TPU. It is a very effective way to promote hydrophilicity of TPU surface by applying free radicals, peroxides (OOR, OOH), and functional groups (SiO 2 , CH 3 , OH, COOH, C=O, and NH 2 [44]) introduced by plasma or grafting of gas or monomers [45] such as O 2 [46,47], He, Ar [48,49], N 2 , CH 4 , C 2 H 2, CO 2 , acetic acid, acrylic acid [50,51], N-isopropylacrylamide (NIPAAm) [52], hexamethyldisilazane (HMDSZ), isopropanol. This hybrid hydrogel made from Chitosan, alginate, and gellan gum three element hydrogel and formed a three-dimensional network hydrophilic polymer.…”

Hybrid hydrogel was fabricated by a classic sol-gel method using EDC/NHS as crosslink reagent grafting onto the thermoplastic polyurethane (TPU), nonwoven fabric, for controlled release of drug. In this study, precursor acetic acid (AA) was used to plasma deposit on the surface of TPU to form a hydrophilic thin film. Hybrid hydrogel was investigated through scanning electron microscopy (SEM), water contact angle (WCA) measurement, Fourier transform infra-red (FTIR) spectroscopy, UV/V is spectroscopy, equilibrium swelling ratio, MTT assay and drug delivery system studies. This polyelectrolyte complexes (PECs) formed hydrogel, pH-sensitive type, was evaluated at pH value of 1.2 and 7.4 of buffer solution and at temperature of 37°C to observe its rate of swelling and drug release features with caffeine. Moreover, the mechanism of caffeine release from membrane devices (n=0.58) are anomalous transport, non-Fickian diffusion, the value of n lies between 0.43 and 0.85. It has an excellent release ratio up to about 90% absorption cumulative amounts of caffeine at pH 7.4 after 8h and could be a beneficial carrier for fragile drugs.
