However, the individual high-purity paraffins, especially the long-chain ones, are labor-intensive and costly to produce and capable of storing and releasing latent heat only within a limited temperature range. Herein, we demonstrate the feasibility of a high-purity paraffin wax fraction (C13\u2013C49) obtained via the Fischer\u2013Tropsch (FT) process as a versatile latent heat storage additive within a wide range of phase transition temperatures (8.1\u201398.2 \u00b0C). To avoid the leakage, the FT wax was encapsulated via nanoemulsion interfacial polymerization of melamine formaldehyde (MF) shells with various core-to-monomer and melamine\/formaldehyde ratios. Differential scanning calorimetry revealed that the latent heat storage capacity of the FT\/MF capsules was 104.5\u2013163.4 J\/g depending on the FT loading efficiency, with the heat storage and release range of \u22120.7\u2013100.2 \u00b0C and \u22129.8\u201385.8 \u00b0C, respectively. The capsules were tested as a thermoregulating additive to commercially available gypsum plaster. Unlike employment of the additives based on individual paraffins, the addition of FT\/MF capsules led to a smooth reduction in heating\/cooling rates of plaster layers in an extended temperature range. This makes FT\/MF capsules a promising and versatile additive for a diversity of thermal energy storage applications.<\/jats:p>","DOI":"10.3390\/polym18091111","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T13:32:21Z","timestamp":1777555941000},"page":"1111","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhancing Gypsum Plaster with Encapsulated Fischer\u2013Tropsch Paraffin Wax as a Phase-Change Additive for Broad-Range Thermal Energy Storage"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1960-6737","authenticated-orcid":false,"given":"Denis","family":"Voronin","sequence":"first","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ekaterina","family":"Smirnova","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nataliya","family":"Demikhova","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0246-8371","authenticated-orcid":false,"given":"Adeliya","family":"Sayfutdinova","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5791-4917","authenticated-orcid":false,"given":"Dmitry","family":"Kopitsyn","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2015-7649","authenticated-orcid":false,"given":"Rawil","family":"Fakhrullin","sequence":"additional","affiliation":[{"name":"Institute of Fundamental Medicine and Biology, Kazan Federal University, Kreml Uram\u0131 18, 420008 Kazan, Republic of Tatarstan, Russia"},{"name":"Biological Institute, Tomsk State University, 36 Lenin Ave., 634050 Tomsk, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir","family":"Vinokurov","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6094-7405","authenticated-orcid":false,"given":"Anna","family":"Stavitskaya","sequence":"additional","affiliation":[{"name":"Department of Physical and Colloid Chemistry, National University of Oil and Gas \u201cGubkin University\u201d, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"112106","DOI":"10.1016\/j.jobe.2025.112106","article-title":"Incorporation of phase change materials into building materials and envelopes for thermal comfort and energy optimization: A comprehensive review","volume":"103","author":"Abass","year":"2025","journal-title":"J.
