The synthetic hydroxyapatite [Ca10(PO4)6(OH)2 (HAP)] based on calcium phosphate has been widely used in the medical and dental areas due to the chemical similarity with the inorganic component of human bone tissue. In this work, hydroxyapatite nanocrystalline powders were synthesized by the solid-state reaction method and sintered with a galactomannan and chitosan blend. The bioceramics studied were prepared from 70%, 80% and 90% of hydroxyapatite with 30%, 20% and 10% of galactomannan and chitosan blends, respectively. The influence of the blend content on the bioceramics was investigated through structural, vibrational, thermal, morphological and dielectric characterizations. It was observed that the increase in the blend percentage promoted an increase in the grain size, which was followed by a decrease in the density and hardness of the samples. The sample with a higher amount of polymeric blend also presented a higher dielectric constant and higher losses.<\/jats:p>","DOI":"10.3390\/cryst13101429","type":"journal-article","created":{"date-parts":[[2023,9,26]],"date-time":"2023-09-26T08:55:01Z","timestamp":1695718501000},"page":"1429","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Influence of Polymeric Blends on Bioceramics of Hydroxyapatite"],"prefix":"10.3390","volume":"13","author":[{"given":"Eduardo da Silva","family":"Gomes","sequence":"first","affiliation":[{"name":"Federal Institute of Maranh\u00e3o (IFMA)\u2014Campus Imperatriz, Research Laboratory, Imperatriz 65919-050, Brazil"}]},{"given":"Ant\u00f4nia Millena de Oliveira","family":"Lima","sequence":"additional","affiliation":[{"name":"Federal Institute of Maranh\u00e3o (IFMA)\u2014Campus Imperatriz, Research Laboratory, Imperatriz 65919-050, Brazil"},{"name":"Foundation for Research and Scientific and Technological Development of Maranh\u00e3o, (FAPEMA), S\u00e3o Lu\u00eds 65075-340, Maranh\u00e3o, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6216-3735","authenticated-orcid":false,"given":"S\u00edlvia Rodrigues","family":"Gavinho","sequence":"additional","affiliation":[{"name":"I3N and Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6858-9507","authenticated-orcid":false,"given":"Manuel Pedro Fernandes","family":"Gra\u00e7a","sequence":"additional","affiliation":[{"name":"I3N and Physics Department, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2217-4584","authenticated-orcid":false,"given":"Susana","family":"Devesa","sequence":"additional","affiliation":[{"name":"CEMMPRE, Centre for Mechanical Engineering, Materials and Processes, Department of Mechanical Engineering, University of Coimbra, Rua Lu\u00eds Reis Santos, 3030-788 Coimbra, Portugal"}]},{"given":"Ana Ang\u00e9lica Mathias","family":"Mac\u00eado","sequence":"additional","affiliation":[{"name":"Federal Institute of Maranh\u00e3o (IFMA)\u2014Campus Imperatriz, Research Laboratory, Imperatriz 65919-050, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1016\/j.matpr.2019.07.712","article-title":"Hydroxyapatite reinforced natural polymer scaffold for bone tissue regeneration","volume":"23","author":"Ragunathan","year":"2020","journal-title":"Mater.
