1 Introduction

Sodium acetate (NaOAc) is a white crystalline powder with the molecular formula C₂H₅O₂Na·2H₂O. It is soluble in water, slightly soluble in ethanol, and insoluble in acetone. Sodium acetate is widely applied in industries such as pharmaceuticals, food, textiles, and printing/dyeing as a buffer, preservative, and stabilizer. Additionally, it exhibits notable antibacterial properties, making it suitable for producing antimicrobial textiles.

Silane coupling agents, organic compounds containing siloxane bonds (typically in the form of Si-OH or Si-Cl), are characterized by their hydrophilicity and durability. They react chemically with various substrates to form stable bonds, improving the physical and chemical properties of materials. These agents hold broad application prospects in coatings, inks, adhesives, and composite materials.

2 Applications of Sodium Acetate in Material Science

2.1 Buffer

As a weak acid salt, sodium acetate dissociates in water to generate acetate ions and sodium ions, neutralizing acidic substances and acting as a buffer. In the pharmaceutical industry, it is commonly used to adjust pH and maintain solution stability. In textiles, it stabilizes dyes, preventing precipitation or discoloration during dyeing.

2.2 Preservative

Sodium acetate inhibits microbial growth and reproduction. In food processing, it functions as a preservative to extend shelf life. It is also employed in manufacturing antibacterial textiles to enhance antimicrobial properties.

2.3 Stabilizer

Sodium acetate forms complexes with metal ions, reducing their adverse effects on polymers. In the rubber industry, it acts as a vulcanization accelerator, speeding up the curing process. In coatings, it prevents pigment settling as an anti-settling agent.

2.4 Other Applications

Sodium acetate is used in producing antistatic agents, thickeners, and emulsifiers. In cosmetics, it serves as a moisturizer, while in agriculture, it improves fertilizer efficiency as a synergist.

3 Applications of Silane Coupling Agents in Material Science

3.1 Surface Modification

Silane coupling agents react with surface hydroxyl groups on substrates to form stable chemical bonds, enhancing surface properties. In coatings, they improve adhesion and weather resistance. In plastics, they increase wear resistance and tear strength. In electronics, they optimize surface resistivity and conductivity of conductive materials.

3.2 Adhesive

These agents strengthen adhesion between dissimilar materials, improving bond strength and durability. In aerospace, they enhance structural integrity and mechanical properties of composites. In automotive manufacturing, they improve component sealing and corrosion resistance.

3.3 Waterproof Coatings

Silane coupling agents crosslink with polar groups in polymers, forming a network structure that boosts waterproof performance. In construction, they enhance the water resistance and weatherability of waterproof membranes.

3.4 Other Applications

They are used as curing agents in polyurethane foams, epoxies, and polyimides. In solar cells, they improve light absorption and photoelectric conversion efficiency. In biomedicine, they enhance the hydrophilicity and biocompatibility of materials.

4 Conclusion and Prospects

Sodium acetate and silane coupling agents hold significant value in material science. Sodium acetate, as a buffer, preservative, and stabilizer, finds widespread use in pharmaceuticals, textiles, and printing/dyeing. Silane coupling agents, as surface-active agents, improve hydrophilicity, durability, and stability in coatings, inks, adhesives, and composites. With technological advancements, their applications in material science will expand further, providing robust support for industrial development.
