The decreasing inter-distance between particles in conjunction with their increasing content as studied by micro-computed tomography (μCT) as well as the inter-melling between GTR and NR matrix were observed. It resulted in a strain localization in the NR matrix at the GTR and NR interface at the origin of mechanical reinforcement upon tensile deformation. In addition, GTR particles were found to show a nucleating ability on strain-induced crystallization (SIC) and elastocaloric properties independently of the particle size. The strain localization was found to relate to a localization of the temperature field, suggesting localization of the elastocaloric effect in NR/GTR blends. The evidence of such heterogeneities would be of interest for the proper design of elastocaloric waste-based rubber composites for heating/cooling applications.18 p.application/pdfengcc-by-nc-nd (c) Budapest University of Technology and Economics, 2022http://creativecommons.org/licenses/by-nc-nd/4.0/ElasticitatCristal·litzacióCautxúElasticityCrystallizationRubberinfo:eu-repo/semantics/article7271872025-06-23info:eu-repo/semantics/openAccess
