The optimized FMP aerogel exhibited low density, good surface hydrophobicity, and mechanical robustness. Additionally, it displayed reliable flame resistance and structural stability, and superior thermal insulation compared to traditional polymer foam materials. This work presents an innovative strategy for developing hydrophobic, flame retardant, and thermal insulating aerogel materials with promising applications.

Summary: Inspired by nature, superhydrophobic surfaces have excellent fouling resistance, and nanocomposite coatings are an economical way to fabricate such surfaces. However, there is limited research on the effects of chemical composition on hydrophobicity and antifouling performance. This study fabricated epoxy-based nanocomposite coatings with varying wettability and found that reducing the solid surface free energy significantly improved the hydrophobicity and antifouling performance of the coatings.

Summary: The phenyl-enhanced flexible silica aerogel, prepared by incorporating PTES into a binary silicon source system, shows improved thermal stability, mechanical properties, and hydrophobicity. With low density, high porosity, and high specific surface area, it exhibits a membrane-like structure derived from PTES, transitioning from a spherical particulate structure to a non-particulate structure. The aerogel demonstrates superior mechanical properties, hydrophobility, thermal stability, and flame resistance, making it suitable for extreme conditions with high temperature and high humidity.

Summary: An environmentally friendly coating with excellent thermal insulation ability was investigated in this study. It uses styrene-acrylic latex as the film-forming material and silica aerogel as one of the fillers. The study found that the coating meets the requirements of use and adding silica aerogel can improve the properties of the coating, but the amount should be controlled within a certain range.

Summary: Polyimide aerogels (PIAs) are promising materials for thermal protection due to their high temperature resistance and low thermal conductivity. In this study, a hybrid formation strategy was proposed to create nanoporous polyimide/silica aerogels (PIAs-A) with exceptional mechanical strength and ultralow thermal conductivity. The PIAs-A exhibited a three-dimensional nanoporous network structure with a pore size distribution of 10-20 nm. The aerogels maintained low temperatures even when in contact with hot surfaces and demonstrated excellent mechanical and thermal stability.

Summary: The experimental analysis of the fracture behavior of recycled opaque PET (rPET-O) containing TiO2 revealed distinct mechanical behavior and fracture properties compared to recycled transparent PET (rPET-T), particularly in the post-yielding region and crack propagation stage, due to the presence of TiO2 particles and matrix cavitation characteristics.

Summary: This study presents experimental results on the mechanical and fracture behavior of three polymeric blends prepared from recycled plastics, with the addition of PET-O significantly increasing the Young's modulus by over a third due to the microfibrillar structure. EWF analysis revealed that the specific essential initiation-related work of fracture was mainly influenced by the microfibrillar structure of the PET-O phase, which greatly improved its value by a factor of three. The results suggest the potential for manufacturing in situ MFCs without a precursor morphology, providing an economic way to increase the recycling rate of PET-O.

Summary: The strain-rate dependence of a commercial grade ABS copolymer in compression and tension has been studied. The hydrostatic pressure-dependence on the material's deformation behavior can be determined through measuring in two loading geometries. An alternative method to determine pressure-dependence, based on the difference in strain-rate dependence for various loading geometries, has been shown to be effective for both thermorheologically simple and complex materials. The study also compared a yield criterion based on a pressure-modified rate equation with finite element simulations, and found that only the fully 3D EGP model can accurately represent large-strain deformation behavior.
