High oxygen barrier property of polyethylene composite films with bilayer polyvinyl alcohol coating for emergency foods in high‐humidity environments

Journal of Applied Polymer Science, Journal Year: 2024, Volume and Issue: 141(16)

Published: Jan. 30, 2024

Abstract The limited oxygen barrier of polyethylene (PE) films has restricted their further application in food packaging, like emergency foods. Although its property can be improved by applying a polyvinyl alcohol (PVA) coating, the PVA/PE composite high‐humidity environments is still challenging. Hence, this study aimed to enhance properties environments. Specifically, PVA coatings were modified itaconic acid (IA) and magnesium‐aluminum layered double hydroxides (LDH), then applied PE as bilayer coating. Because unique coating on surface, film (IA/LDH‐p) been improved. results confirmed that IA/LDH‐p had an permeability coefficient 1.92 ± 0.16 × 10 −16 cm 3 cm/(cm 2 s Pa) under environment test, 82.42% better than single‐layer coated surface. After being stored at RH 90% for 36 h, tensile strength elongation break values 27.20 MPa 919.63%, respectively. Overall, obtained showed great potential foods particularly

Poly(vinyl alcohol) Composite Aerogel toward Lightweight, Remarkable Flame Retardancy, and Thermal Insulation Properties by Incorporating Carbon Nanohorns and Phytic Acid

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(14), P. 8027 - 8039

Published: July 12, 2024

In this work, an aerogel with excellent flame retardancy, enhanced compression modulus, and efficient thermal insulation was developed from poly(vinyl alcohol) (PVA), biobased phytic acid (PA), single-walled carbon nanohorns (SWCNHs). The microstructural evolution of the freeze-dried PVA/PA/SWCNH composite aerogels revealed that varied amounts could influence three-dimensional architecture. Especially, when concentration PA 1.5%, PVA/PA/SWCNHs a tightly arranged "short tubes" structure had high compressive modulus 2.02 MPa, corresponding to specific 20.2 MPa cm3/g. Compared PVA/SWCNHs aerogel, showed better fire as confirmed by limited oxygen index (LOI) tests cone calorimetry (CC) tests. Notably, introduction at 1.5% resulted in LOI values up 49.8 ± 0.1% pHRR THR were dramatically reduced 74.3 81.0%, respectively. addition, different concentrations exhibited performance slightly lower conductivity (32.2–46.9 mW/(m K)) resisted ∼1300 °C flame. Meanwhile, synergistic retardancy between SWCNHs also analysis char residues gas-phase products. These unique characteristics make promising multifunctional candidate for applications aviation, aerospace, other fields.
