“…In their study, they discussed in detail the implementation, experimental methodology, and computational procedure of the method and proved the validity of the multiple-relaxation-time lattice Boltzmann model (MRT LB model). In the same year, the group [99] used computational simulations using the lattice Boltzmann method to complement the assessment of the swelling behavior of hydrogel samples of cylindrical and parallel hexagonal shapes. Later, Boschetti et al [100] utilized finite elements and FDM to simulate the free swelling of 3D hydrogels.…”

Hydrogel sweat cooling is one of the leading areas in the study of multiphase heat transfer. In this study, the principles, applications, current research status, and future trends of hydrogel sweat cooling technology are comprehensively reviewed. By combing through and analyzing the relevant literature, the research progress in hydrogel sweat cooling is presented from the application perspective, including its use in electronic devices, buildings, and clean-energy facilities. The principle of each application is illustrated, the research status is established, and pros and cons are proposed. To provide inspiration for future research, the development trend is set out. Our literature review indicates that research on advanced hydrogels is the most promising research direction, including studies on the effect of environmental and indoor factors on sweat cooling performance through numerical, experimental, and theoretical means. Challenges for future research mainly include conducting hydrogel numerical analysis which can be experimentally verified, developing advanced hydrogels in a green way, and achieving the precise regulation of hydrogel control through intelligent methods. Interdisciplinary integration might be promising as well due to the fact that it can reveal the hydrogel sweat cooling mechanism from a different perspective. This study aims to promote multiphase cooling technology in exploring the application of hydrogels in energy utilization criteria.

“…The dose-response sigmoidal model for drugs delivery can be considered appropriated to identify regions of toxic effect and regions of therapeutical effect [97]. Boltzmann release can be associated with the hydrogel relaxation [98], related to-Fickian diffusion-controlled release [99]. Since Aloe vera mucilage can be quickly released to aqueous media [100], it is expected that the media exchange place with the Aloe vera mucilage (low swelling degree), destabilizing the integrity of the gel (high weight loss).…”

Delivery kinetics of natural active agents by PVA hydrogels intended for wound care

et al. 2023

Acute wound dressings can be based on PVA hydrogels, which present many characteristics of an ideal dressing, e.g., fluid uptake, a moisturized environment, etc. The lack of antimicrobial properties leads to the addition of natural active agents. The present work aims to manufacture and compare PVA gels loaded with Barbatimão bark extract, Leucaena bark extract, Aloe vera, and Lavender essential oil. They were characterized by FTIR, swelling tests, SEM, actives release. There were interactions between PVA and the active agents. The addition of Leucaena and Barbatimão increased the PVA ability to swell, but the opposite was found for Aloe vera and Lavender essential oil. PVA-Lavender essential oil samples presented interconnected pores, while samples with essential oil or extracts presented high crystallinity. Lavender essential oil and Aloe vera presented the highest release. The Barbatimão and Leucaena samples' release may be related to the samples' swelling, but the initial release of Aloe vera and Lavender samples was diffusion controlled by swelling. Their long-term release was dose-dependent for Aloe vera, while it was a non-Fickian diffusion for Lavender essential oil related to the hydrogel's relaxation step. There is a synergistic effect when Aloe vera and Lavender essential oil are loaded in PVA hydrogels.
