Abstract
Carbonaceous materials are widely studied for its unique properties such as conducting heat, electricity efficiency, mechanical strength and improving properties of composite materials. However, due to the poor dispersibility and chemically inertness, applications of unmodified carbonaceous materials are limited. Therefore, introducing reactive groups or linker molecules to carbonaceous materials would allow to customize their interfacial properties. Herein, first of all, a non-destructive method was used for amination of carbonaceous materials with linker molecules. We have used N-(3-Acetylaminopropyl) amino acetic acid as linker molecule for amination of graphitic materials using 1,3-dipolar cycloaddition. Furthermore, 3-Aminopropyl) triethoxysilane (APTES) was also used for amination of graphene. Second, a mechanochemical approach was used to functionalize of graphite with linker molecules. Maleimide derivatives were used as linker molecules to functionalize graphite using stainless steel ball-mill which by the tandem exfoliation and [4+2] cycloaddition (Diels-Alder) reaction. Third, carbon quantum dots were synthesized using facile hydrothermal method & their amination with (3-Aminopropyl) triethoxysilane (APTES) will be studied for imaging colon cancer tissues. Additionally, a facile method to monitor the transfer of single graphene sheets to Si substrate from Cu foil was developed. Last but not least, timed release of homoserine lactone (a quorum sensing bacterial agent) from carbonaceous materials will be studied.
