In the present work, several polymer\/nanocomposite types based on two different linear low-density polyethylenes (LLDPEs), as well as polylactic acid (PLA), reinforced with carbon nanotubes (CNTs) or a combination of CNTs\/carbon nanofibers (CNFs) with graphene oxide (GO) at various loadings were investigated. The thermal diffusivity results for monofiller and hybrid nanocomposites with varying nanofiller loadings were analyzed. Additionally, existing models were employed to simulate the thermal conductivity using experimental data of both monofiller and hybrid nanocomposites. The model parameter values were utilized to explore the mechanism of the thermal conductivity increase, the role of CNTs and the synergistic effects of hybrid nanocomposites.<\/jats:p>","DOI":"10.3390\/nano16181162","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T13:33:42Z","timestamp":1789479222000},"page":"1162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Experimental Study and Model Simulation of the Effective Thermal Conductivity of Polymer\/Carbonaceous Nanocomposites"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7222-612X","authenticated-orcid":false,"given":"Panagiotis A.","family":"Klonos","sequence":"first","affiliation":[{"name":"Physics Department, School of Applied Mathematical and Physical Sciences, National Technical University of Athens, 15780 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5893-7849","authenticated-orcid":false,"given":"Apostolos","family":"Kyritsis","sequence":"additional","affiliation":[{"name":"Physics Department, School of Applied Mathematical and Physical Sciences, National Technical University of Athens, 15780 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evagelia","family":"Kontou","sequence":"additional","affiliation":[{"name":"Mechanics Department, School of Applied Mathematical and Physical Sciences, National Technical University of Athens, 15780 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"463","DOI":"10.1615\/JEnhHeatTransf.2020034592","article-title":"Thermal Conductivity Enhancement of Polymers via Structure Tailoring","volume":"27","author":"Xu","year":"2020","journal-title":"J.
