一般描述

(3-Aminopropyl)triethoxysilane (APTES) is a versatile organosilane widely used in material science for surface modification and functionalization. Its structure contains a triethoxysilane group that hydrolyzes in the presence of moisture to form silanol groups, which can covalently bond with hydroxylated surfaces such as glass, silica, and metal oxides. Additionally, the terminal amino group (-NH₂) allows for further reaction with a wide range of organic or polymeric functional groups, making APTES an effective molecular bridge between inorganic and organic phases. This bifunctionality makes it ideal for improving adhesion in composites, creating self-assembled monolayers (SAMs), and enhancing the compatibility and dispersion of nanoparticles in various matrices. APTES is also compatible with sol-gel processes and exhibits good thermal stability, making it suitable for use in sensors, coatings, electronic devices, and hybrid nanomaterials.

应用

3-Aminopropyl)triethoxysilane (APTES) can be used :
  • For the surface functionalization of silica nanoparticles to enhance their colloidal stability.
  • As a self-assembled monolayer (SAM) in the fabrication of amorphous silicon thin-film solar cells, to enhance their performance and stability.
  • To modify zinc oxide quantum dots for enhancing the performance of fluorescent orthodontic adhesives.
  • Synthesis of Fe3O4@SiO2/APTS/Ru magnetic nanocomposite catalyst for hydrogenation reactions

特点和优势

  • (≥98.0%) ensures effective bonding and modification without the interference of impurities, leading to improved adhesion and durability of coatings.
  • The absence of contaminants allows for consistent performance in enhancing the compatibility between organic and inorganic materials, resulting in stronger and more reliable composites.
  • It ensures that the functional groups are readily available for reactions, leading to efficient immobilization and improved sensitivity of biosensors.
