The simultaneous enhancement in strength and toughness seems to be an intrinsic contradiction in multiple material designs, including the structural regulation of polymer composites. In this study, benzimidazole-containing aromatic-polyamide thin films are used as typical rigid polymers with high strength and modulus to study their strength-toughness collaboration via a multi-scaled stress distribution mechanism. A fully organic deformable filler with a fractal structure is designed. Utilizing the large-scale deformability of the filler to absorb the energy and dislocation node structure of the filler to disperse the stress, the composite thin film is significantly toughened, which is reflected in the elongation at break increased by 144.9% and energy at break increased by 154.2%. In addition, the specific fractal structure of the filler provided a larger interaction area, which enhanced the interfacial bonding force and improved the strength of the film. Moreover, owing to the larger interaction area provided by the fractal structure, the interface bonding force between the filler and matrix due to the similar chem. structures is further improved and the tensile strength of the composite thin film is increased from 389.2 ± 11.98 to 426.2 ± 4.41 MPa. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Reference of 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Reference of 4422-95-1
