Description

Application

• Enhanced Efficiency and Stability in Nanocrystal-Based LEDs: Octylamine was found to improve the stability and efficiency of CsPbI3 nanocrystal-based light-emitting diodes by influencing the integrity and performance of the nanocrystals, leading to significant improvements in device longevity and performance (H Li, W Dong, X Shen, C Ge, Y Song - The Journal of Physical Chemistry C, 2022) [source].
• Graphene Oxide Functionalization: A study on octylamine-functionalized graphene oxide explores its electrochemical stability and potential for hydrogen evolution, highlighting its utility in energy applications and hydrophobic coatings (N Palaniappan, IS Cole, AE Kuznetsov - RSC Advances, 2020) [source].
• pH-responsive Surface Modification: Octylamine was used to modify the surfaces of carboxylated aluminium oxide, enhancing their hydrophobic properties through covalent bonding, which could be advantageous in various material science applications (S Alexander, L Morrow, AM Lord, CW Dunnill - Journal of Materials Chemistry A, 2015) [source].
• Improving Mechanical Properties of Natural Rubber: The addition of octylamine in natural rubber composites was shown to coordinate with zinc ions, enhancing the dispersion of ZnO and improving the mechanical robustness of the material (YC Wei, D Zhu, J Zhang, HR Wang, MZ Zhou - International Journal of Biological Macromolecules, 2023) [source].
