  • Publication number: 20220135764
    Abstract: The present invention aims to obtain a resin composition with low thermal expansion property by suppressing functional deterioration in negative thermal expansion property when a negative thermal expansion material is added to a thermoplastic resin and heat-processed. The present invention provides a resin composition including metal oxide particles and a thermoplastic resin, both having a negative thermal expansion property. The negative thermal expansion of the particles is attributed to a crystal phase transition, which is driven by electron transfer between the constituent metals, and a covalent protective layer that inhibits the electron transfer is formed between the particles and the thermoplastic resin.
