“…However, exceptions exist, particularly for the magnetic stirring method, which requires an elevated temperature [31]. Regarding the processing times, solid grinding typically proceeds rapidly [4,12], whereas mechanical stirring, magnetic stirring, and sonication demand more extended durations to ensure thorough mixing and homogeneity with the fillers [7,31,32]. Table 8 also exhibits the mixing methods utilized to fabricate hybrid polymer composites.…”

“…This design strategy diverges from the conventional reinforcementbased approach by emphasizing the integration of diverse polymer constituents. For example, a hybrid polymer composite could involve blending two or more polymers, each contributing distinct attributes to the final material [4]. This blending of polymers results in a composite with tailored properties that surpass the individual capabilities of the constituent polymers.…”

Polymer hybrid composites and hybrid polymer composites are distinct but interconnected composite classes, each with unique compositions and design philosophies. The mechanical properties of these composites are vital in advanced materials due to their impacts on performance, durability, and suitability for various applications. The addition of ionic liquids into these composites is a promising innovation in advanced materials. In this short review, various polymer matrices (e.g., thermosets, thermoplastics, and biopolymers), fillers (e.g., inorganic, carbon, organic, and metal), and ionic liquids (e.g., imidazolium- and phosphonium-based) used to fabricate polymer hybrid composites and hybrid polymer composites with added ionic liquids are identified. Furthermore, the addition of ionic liquids into these composites through different methods (e.g., magnetic stirring, mechanical stirring, solid grinding, etc.) is discussed. The influence of ionic liquid addition on the mechanical properties, specifically the tensile properties of these composites, is also shortly reviewed. The changes in the tensile properties, such as the tensile strength, tensile modulus, and elongation at break, of these composites are explained as well. The information presented in this review enhances the understanding of the methods applied to add ionic liquids into polymer hybrid composites and hybrid polymer composites, along with their tensile properties. In short, some ionic liquids have the capacity to enhance the tensile properties of hybrid polymer composites, and several ionic liquids can reduce the tensile properties of polymer hybrid composites.

Nanomaterials as additives are effective for improving the strength, toughness, corrosion resistance, and wear resistance of polymer coatings. The dimensionality of nanomaterials (0D, 1D, and 2D) has a significant influence on the anticorrosion performance and mechanism. It is also desired to develop composite additives using two or more nanomaterials (0D/1D, 1D/2D, and 0D/2D) to further enhance the anticorrosion performance of polymer coatings. In this Review, nanomaterials as additives are categorized according to their dimensionality. Their anticorrosion performance and microscopic mechanism are comprehensively summarized and discussed. Then, the synergistic effects of composite additives, which consist of two or more nanomaterials, are discussed in detail. Finally, the current issues and research prospects of nanomaterials as anticorrosion additives for polymeric coatings are discussed.

The growing study of polymer composites has motivated scientists to explore more methodologies to enhance the final demanding properties of polymer composites. Polymer composites have commonly been fabricated using thermosets or thermoplastics with synthetic or natural fillers. Lately, ionic liquids have been applied as coupling agents for polymer composites. In this succinct review, two types of ionic liquids, specifically imidazolium‐ and phosphonium‐based ionic liquids that are applied as coupling agents, are identified. Additionally, the synthesis of ionic liquids with different precursors and reactions is explained. The coupling effect of ionic liquids on the mechanical, thermal, and chemical properties of polymer composites is also succinctly reviewed. The knowledge shown in this review gives a more transparent comprehension of the fabrication of polymer composites coupled with ionic liquids and the essential properties of polymer composites. In conclusion, most imidazolium‐ and phosphonium‐based ionic liquids can improve several mechanical, thermal, and chemical properties of thermoset and thermoplastic composites.
