Such systems are developed for multilayer corrosion protective coatings. A sorption model was developed to calculate the moisture concentration field in the multilayer structures using Fick\u2019s law of diffusion. The finite-difference method was used for the numerical solution. Epoxy\/LDH nanocomposites were prepared using various dispersion methods with solvents, wetting agents, and via a three-roll mill. Moisture absorption was measured under different environmental conditions, including temperatures up to 50 \u00b0C and salinity levels up to 26.3 wt% salt solution. The results showed that equilibrium moisture content increased by 50% in hot water, while it was reduced by up to two times in salt solution. The diffusion coefficient in hot water increased up to four times compared to room temperature. The numerical algorithm was validated against experimental data, accurately predicting moisture distribution over time in complex polymer systems. Mechanical tests revealed that the elastic modulus did not change after water exposure; however, the ultimate strength decreased by 10\u201315%, especially in specimens with 5 wt% LDH.<\/jats:p>","DOI":"10.3390\/polym16233388","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T13:34:04Z","timestamp":1733146444000},"page":"3388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Moisture Absorption and Mechanical Degradation of Polymer Systems Incorporated with Layered Double Hydroxide Particles"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7945-2410","authenticated-orcid":false,"given":"Stanislav","family":"Stankevich","sequence":"first","affiliation":[{"name":"Institute for Mechanics of Materials, University of Latvia, Jelgavas St. 3, LV-1004 Riga, Latvia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1241-0803","authenticated-orcid":false,"given":"Daiva","family":"Zeleniakiene","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Kaunas University of Technology, Student\u0173 St. 56, 51424 Kaunas, Lithuania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1198-6202","authenticated-orcid":false,"given":"Jevgenijs","family":"Sevcenko","sequence":"additional","affiliation":[{"name":"Institute for Mechanics of Materials, University of Latvia, Jelgavas St. 3, LV-1004 Riga, Latvia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8889-6451","authenticated-orcid":false,"given":"Olga","family":"Bulderberga","sequence":"additional","affiliation":[{"name":"Institute for Mechanics of Materials, University of Latvia, Jelgavas St. 3, LV-1004 Riga, Latvia"}]},{"given":"Katerina","family":"Zetkova","sequence":"additional","affiliation":[{"name":"SYNPO a.s., S.
