Silicon Dioxide Nanowires

Product Overview
Silicon dioxide nanowires are nanomaterials with a one-dimensional structure, featuring a diameter of approximately 20-30 nm and a length greater than 100 micrometers. Due to their elongated form and large aspect ratio, these nanowires exhibit exceptional physical and chemical properties. They demonstrate superior mechanical performance, surface chemical reactivity, and unique electrical characteristics compared to bulk silicon dioxide materials. The high strength and toughness of silicon dioxide nanowires, along with their size-dependent effects, make them highly suitable for applications in the mechanical, electronic, and chemical fields.

Key Features

• Surface Chemical Reactivity:The surface of silicon dioxide nanowires is rich in silanol groups (Si-OH), allowing for reactions with other chemicals. This makes them suitable for surface modifications to alter their hydrophilicity, hydrophobicity, or biocompatibility, expanding their range of applications.
• Chemical Stability:In conventional environments, silicon dioxide nanowires exhibit good chemical stability and are resistant to reactions with most common chemicals. However, they may dissolve or undergo surface modification in strong acidic or alkaline conditions.
• Enhanced Mechanical Properties:Due to their high strength and toughness, silicon dioxide nanowires significantly enhance the mechanical performance of composite materials.

Applications

• Micro-Nano Device Assembly:With excellent insulation and mechanical properties, silicon dioxide nanowires are ideal for assembling micro-nano devices.
• Industrial Catalysis:As catalyst supports, silicon dioxide nanowires improve the efficiency and stability of catalytic reactions.
• Polymer Reinforcement:Adding silicon dioxide nanowires to polymers can significantly enhance the strength and toughness of the material.
• Cosmetic Whitening and UV Protection:Used in cosmetics, silicon dioxide nanowires can provide whitening effects and offer UV protection, safeguarding the skin from harmful UV radiation.
