  • Publication number: 20230167220
    Abstract: Herein presented is a high electrical conductivity, uniform, material based on nanoparticles-Li+-polycarboxylate grafted few-layer graphene oxide including perovskite type nanoparticles for filler in polymeric matrices, in direct and reverse osmosis membranes, in lithium batteries, among others. The material is obtained by a method comprising the step of: preparation of a composite material having polymers with mono- or di-acid groups covalently bonded to graphene; optionally further comprising the preparation of a composite material with graphene covalently bonded to polymers having mono- or di-acid groups that have been replaced by lithium ion; and optionally further comprising the preparation of a composite material with graphene covalently bonded to polymers having mono- or di-acid groups that have been replaced by lithium ion in addition to grafted nanoparticles, including nanoparticles perovskite type.

  • Patent number: 8664308
    Abstract: The present invention relates to compatibilizers to be used for obtaining materials called polyolefin nanocomposites, microcomposites and polymer blends, and it includes the process for obtaining such compatibilizers. Such compatibilizers are obtained from the monomers of the organic compounds itaconic acid (ITA) or its monooctadecyl itaconate (MODIT) derivative. The compatibilizers are polyolefins grafted with those monomers, which are characterized by having functional groups with a hydrophilic character and a polymer backbone with a hydrophobic character. The compatibilizers of this invention are characterized by having controlled degrees of grafting of these monomers, and they can be used optimally in various applications. It also relates to the process for obtaining such compatibilizers.
