The properties of rubber materials are dependent on the characteristics of the elastomer matrix, the filler type, the cross-linking agent, the number of ingredients, and their interactions. In the previous article, we showed that chloroprene rubber can be efficiently cross-linked with copper(I) oxide or copper(II) oxide. During the processing of rubber compounds, the incorporation of a filler and a curing substance are two substantial parameters, such as the homogeneity of mixing and cross-linking that significantly affect the properties of the vulcanizates. Therefore, this work aimed to evaluate the curing characteristics, mechanical and dynamical properties, morphology, and flammability of the composites containing chloroprene rubber cross-linked with Cu2O or CuO and filled with different fillers (silica, carbon black, montmorillonite, kaolin, chalk). It was found that the type of filler and curing agent had a significant impact on the degree of cross-linking of the chloroprene rubber and the properties of its vulcanizates. The degree and speed of the cross-linking of filled CR were higher when the CR was cured with copper(II) oxide. Among the fillers used, the presence of carbon black or silica ensured the highest degree of CR cross-linking and the most useful properties. The flammability tests indicated that all produced vulcanizates were characterized by a high oxygen index, which allows them to be classified as non-flammable materials.

Triboelectric nanogenerators (TENGs) that utilize triboelectrification and electrostatic induction to convert mechanical energy to electricity have attracted increasing interest in the last 10 years. As a universal physical phenomenon, triboelectrification can occur between any two surfaces that experience physical contact and separation regardless of the type of material. For this reason, many materials, including both organic and inorganic materials, have been studied in TENGs with different purposes. Although organic polymers are mainly used as triboelectric materials in TENGs, the application of inorganic nanomaterials has also been intensively studied because of their unique dielectric, electric, piezoelectric, and optical properties, which can improve the performance of TENGs. A review of how inorganic nanomaterials are used in TENGs would help researchers gain an overview of the progress in this area. Here, we present a review to summarize how inorganic nanomaterials are utilized in TENGs based on the roles, types, and characteristics of the nanomaterials.

A strategy to enhance the energy conversion performance of a cement-based triboelectric nanogenerator (TENG) has been proposed for large-scale energy harvesting from human footsteps. A cement-carbon black (CB) composite is fabricated by incorporating CB nanoparticles with a hydroxyethyl cellulose (HEC) admixture and used as a triboelectric material for TENG. The fabricated cement-CB@HEC TENG exhibits a 13fold enhancement of the electrical output with the highest power density of 2.38 W/m 2 . The tremendous improvement is ascribed to a good dispersion of conductive CB nanoparticles in the cement matrix, which is key for achieving a high dielectric constant that is required to intensify the triboelectric charge density of TENG. Moreover, it was found that the addition of the HEC admixture plays a crucial role in not only providing a good dispersion of CB for generating dielectric polarization but also facilitating the development of a microstructure and crystallization of cement hydration products to reduce the formation of air voids and micropores. These factors synergistically contribute to the improved dielectric constant and compressive strength of the cement-CB@HEC composite. This remarkable strategy presents great prospects for the development of smart cement materials for realizing applications in large-scale energy harvesting toward sustainable, clean, and renewable energy sources.
