“…Therefore, a composite water-absorbent material prepared from it exhibits good water absorption and is significant for environmental protection. AMPS is a solid anionic watersoluble monomer containing strong hydrophilic groups with good salt resistance, acid-base resistance, and hydrolytic stability [17,24]. ATP is an aqueous magnesium-aluminum-rich layered chain silicate mineral with a particular fibrous crystal structure and a large surface area, having a theoretical chemical formula of Mg 5 Si 8 O 20 (HO) 2 (OH 2 ) 4 •4H 2 O [25,26].…”

Attapulgite-hydroxyethyl cellulose-poly (acrylic acid-co-2-acrylamide-2-methylpropanesulfonic acid) (ATP-HEC-P(AA-co-AMPS)) in-concrete curing material was synthesized by aqueous solution polymerization using attapulgite (ATP) as an inorganic filler and hydroxyethyl cellulose (HEC) as a backbone. The effects of relevant factors such as ATP dosage, HEC dosage, degree of neutralization, initiator quality, and cross-linking agent quality on the water absorption characteristics of ATP-HEC-P (AA-co-AMPS) were investigated through expansion tests. The micro-morphology of ATP-HEC-P (AA-co-AMPS) was also comprehensively characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, a thermal analysis, and other applicable means. The results showed that the prepared ATP-HEC-P (AA-co-AMPS) had a strong water absorption and water retention capacity, with a water absorption multiplicity of 382 g/g in deionized water and 21.55% water retention capacity after being placed at room temperature for 7 d in a bare environment. Additionally, ATP-HEC-P (AA-co-AMPS) showed good performance for absorbing liquids within the pH range of 7–12. The material’s thermal stability and mechanical properties were also significantly improved after the addition of ATP. The preparation cost is low, the process is simple, and the material meets the requirements for concrete curing materials.

The limited oxygen barrier of polyethylene (PE) films has restricted their further application in food packaging, like emergency foods. Although its oxygen barrier property can be improved by applying a polyvinyl alcohol (PVA) coating, the application of PVA/PE composite films in high‐humidity environments is still challenging. Hence, this study aimed to enhance the oxygen barrier properties of PVA/PE composite films in high‐humidity environments. Specifically, PVA coatings were modified by the itaconic acid (IA) and magnesium‐aluminum layered double hydroxides (LDH), and then applied to PE films as bilayer coating. Because of the unique bilayer coating on the PE surface, the oxygen barrier property of PVA/PE composite film (IA/LDH‐p) in high‐humidity environments has been further improved. The results confirmed that IA/LDH‐p had an oxygen permeability coefficient of 1.92 ± 0.16 × 10−16 cm3 cm/(cm2 s Pa) under a high‐humidity environment test, 82.42% better than that of single‐layer coating coated on PE surface. After being stored at RH 90% for 36 h, the tensile strength and elongation at break values of IA/LDH‐p were 27.20 MPa and 919.63%, respectively. Overall, this obtained PVA/PE composite films showed great potential for application in emergency foods packaging, particularly in high‐humidity environments.
