Summary: Introduced in 1954, polyurethane foams gained popularity due to their light weight, high chemical stability, and excellent sound and thermal insulation properties. Despite their versatile applications, the high flammability of polyurethane foams limits their use. Nanoscale materials show potential as flame-retardant additives to improve the fireproof properties of polyurethane foams. This review focuses on the recent progress in modifying polyurethane foams with nanomaterials to enhance their flame retardance, including different types of nanomaterials and methods of incorporation, as well as the synergistic effects with other flame-retardant additives.

Summary: The development of thermally conducting electrical insulators plays a critical role in thermal management applications for advanced electronics and electrical devices. In this study, polymer nanocomposite films composed of various polymers and dielectric fillers were synthesized using a layer-by-layer technique. The thermal conductivity of the films was measured, and factors such as film growth, filler type, filler volume fraction, polymer chemical structures, and temperature were found to affect the thermal conductivity. Comparisons with theoretical models were made to understand the heat transfer behavior in such layered films composed of dielectrics and polymers.

Summary: This article reports on the synthesis and evaluation of starch nanoparticles (SNP) as nanofillers to improve the properties of polyurethane (PU) films using ultrasound-assisted acid hydrolysis. The study found that the addition of SNP to the PU matrix increased the roughness of the surface, lowered water vapor permeability, increased the glass transition temperature, and enhanced the microbial barrier properties of the film. Furthermore, an increase in the SNP content also improved the toughness and barrier properties of the film.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.
