The obtaining method is the in situ emulsion polymerization of the (poly urea-formaldehyde) (PUF) coatings. The microcapsules were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM), high-performance liquid chromatography (HPLC), and low-field nuclear magnetic resonance (NMR) techniques. The optimal formation of uniform microcapsules is achieved at a stirring speed of 800 rpm and centrifugation is no longer necessary. HPLC demonstrates that the microcapsules formed at 800 rpm show a better control of liquid release than the heterogeneous ones obtained at a lower stirring speed. The centrifuged samples have rounded shapes, with dimensions between 80 and 800 nm, while the non-centrifuged samples are more uniform, with a spherical shape and dimensions of approximately 800 nm.<\/jats:p>","DOI":"10.3390\/nano14221853","type":"journal-article","created":{"date-parts":[[2024,11,20]],"date-time":"2024-11-20T03:57:04Z","timestamp":1732075024000},"page":"1853","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Synthesis and Characterization of Microcapsules as Fillers for Self-Healing Dental Composites"],"prefix":"10.3390","volume":"14","author":[{"given":"Maria Amalia","family":"T\u0103ut","sequence":"first","affiliation":[{"name":"Physics and Chemistry Department, Technical University of Cluj-Napoca, 103-105 Bulevardul Muncii Street, 400641 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9714-4809","authenticated-orcid":false,"given":"Marioara","family":"Moldovan","sequence":"additional","affiliation":[{"name":"Raluca Ripan Institute for Research in Chemistry, Babe\u0219-Bolyai University, 30 Fantanele Street, 400294 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6536-7696","authenticated-orcid":false,"given":"Miu\u0163a","family":"Filip","sequence":"additional","affiliation":[{"name":"Raluca Ripan Institute for Research in Chemistry, Babe\u0219-Bolyai University, 30 Fantanele Street, 400294 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3274-8817","authenticated-orcid":false,"given":"Ioan","family":"Petean","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Engineering, Babes-Bolyai University, 11 Arany Janos Street, 400028 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2960-9832","authenticated-orcid":false,"given":"Codru\u0163a","family":"Saro\u015fi","sequence":"additional","affiliation":[{"name":"Raluca Ripan Institute for Research in Chemistry, Babe\u0219-Bolyai University, 30 Fantanele Street, 400294 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9812-695X","authenticated-orcid":false,"given":"Stanca","family":"Cuc","sequence":"additional","affiliation":[{"name":"Raluca Ripan Institute for Research in Chemistry, Babe\u0219-Bolyai University, 30 Fantanele Street, 400294 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian Catalin","family":"Taut","sequence":"additional","affiliation":[{"name":"Applied Electronics Department, Technical University of Cluj-Napoca, 26-28 George Bari\u021biu Street, 400027 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8082-6600","authenticated-orcid":false,"given":"Ioan","family":"Ardelean","sequence":"additional","affiliation":[{"name":"Physics and Chemistry Department, Technical University of Cluj-Napoca, 103-105 Bulevardul Muncii Street, 400641 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viorica","family":"Laz\u0103r","sequence":"additional","affiliation":[{"name":"Department of General Medicine, Vasile Goldis University of Medicine, 310048 Arad, Romania"},{"name":"Pediatric Clinic II, Clinical Hospital Emergency of Arad County, 310037 Arad, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sorin Claudiu","family":"Man","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy Cluj-Napoca, 400124 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1111\/j.1834-7819.2010.01296.x","article-title":"Resin composite restorative materials","volume":"56","author":"Ilie","year":"2011","journal-title":"Aust.
