However, achieving filler-derived functionalities harmoniously with their dynamic characteristics is highly momentous in VNCs. Herein, the vitrimeric thiol-epoxy matrix incorporating tyre-waste-derived carbon nanosheets (CNS) is shown as a versatile nanocomposite integrating flexibility, high strength, and tunable electrical conductivity, together with self-healing and shape-memory characteristics. The transesterification-aided bond exchange reactions enabled vitrimeric features, while the CNS endorsed electrical transport, mechanical, thermal, and dimensional stabilities. Primary investigations, together with ultra-small angle X-ray scattering, explored the structural integrity of dispersed CNS. The hierarchically dispersed nanofillers provided efficient conductive pathways, offering a systematically varying electrical conductivity with filler concentration. They exhibited excellent dimensional stability even after multiple healing cycles, along with an exceptional stretchability up to 276%. Compared with the pristine matrix, a threefold increase in storage modulus has been observed at the maximum filler loading (15 wt%). They exhibited a commendable balance between the rigidity offered by CNS and excellent matrix flexibility, showing their versatility. As a result of accelerated thermoresponsive bond-exchange reactions, a complete shape recovery with an impressive healing efficiency of 99.6% is observed. This study not only provides a detailed elucidation of a multifunctional system but also offers practical insights for developing highly efficient epoxy-based vitrimers suitable for a wide range of applications.<\/jats:p>","DOI":"10.3390\/polym18192318","type":"journal-article","created":{"date-parts":[[2026,9,22]],"date-time":"2026-09-22T15:28:43Z","timestamp":1790090923000},"page":"2318","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Study of Structural and Multifunctional Characteristics in Dynamic Transesterification-Aided Epoxy Carbon Nanocomposites"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-0137-8074","authenticated-orcid":false,"given":"Vaishnav","family":"B","sequence":"first","affiliation":[{"name":"Department of Physics, Applied Science Cluster, UPES, Dehradun 248007, India"},{"name":"Deutsches Elektronen-Synchrotron DESY, Notkestr. 85, 22607 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Halsi","sequence":"additional","affiliation":[{"name":"Department of Physics, Applied Science Cluster, UPES, Dehradun 248007, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4430-6875","authenticated-orcid":false,"given":"Ajay","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Physics, Applied Science Cluster, UPES, Dehradun 248007, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9215-7563","authenticated-orcid":false,"given":"Sravendra","family":"Rana","sequence":"additional","affiliation":[{"name":"Department of Physics, Applied Science Cluster, UPES, Dehradun 248007, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3483-3310","authenticated-orcid":false,"given":"Sarathlal","family":"Koyiloth Vayalil","sequence":"additional","affiliation":[{"name":"Department of Physics, Applied Science Cluster, UPES, Dehradun 248007, India"},{"name":"Deutsches Elektronen-Synchrotron DESY, Notkestr. 85, 22607 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"112343","DOI":"10.1016\/j.eurpolymj.2023.112343","article-title":"Vitrimer Chemistry for 4D Printing Formulation","volume":"197","author":"Gerdroodbar","year":"2023","journal-title":"Eur.
