Cross-linking is a process where chemical bonds are formed between polymer chains, enhancing the material's mechanical strength, thermal stability, and resistance to solvents. This technique is widely used in the production of various materials such as plastics, rubber, and hydrogels, significantly altering their physical properties to meet specific application requirements.

Cross-linking

Chemical bonds are the attractive forces that hold atoms together in molecules and compounds, resulting from the interactions between their electrons. They are fundamental to the structure and properties of matter, influencing chemical reactivity, stability, and the formation of new substances through chemical reactions.

Mechanical strength refers to the ability of a material to withstand an applied load without failure or plastic deformation. It is a critical property in engineering and construction, influencing the durability and safety of structures and components.

mechanical strength

Thermal stability refers to the ability of a substance to maintain its physical and chemical properties at elevated temperatures. It is a critical factor in determining the suitability of materials for high-temperature applications and influences their degradation, decomposition, or phase change behaviors.

Hydrogels are three-dimensional polymer networks that can absorb and retain significant amounts of water, making them highly versatile for applications in medicine, agriculture, and environmental management. Their unique properties, such as biocompatibility and tunable mechanical strength, allow for innovative uses in drug delivery systems, wound care, and tissue engineering.

hydrogels

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity. These properties are crucial for identifying, classifying, and using materials in various scientific and industrial applications.
