Preparation of water dispersible carbon nanotubes using photoinduced hyperbranched copolymerization and noncovalent interactions was written by Un, Merve;Temel, Gokhan. And the article was included in European Polymer Journal in 2018.Category: bromides-buliding-blocks The following contents are mentioned in the article:
Amine containing methacrylic-based hyperbranched copolymers were prepared according to type II photoinitiation methodol. in the presence of a com. available photoinitiator. Several feed ratios of 2-(diethylamino)ethyl methacrylate and Me methacrylate monomers were used to obtain copolymers with varying branching densities. Resulting copolymers were easily modified using pyrene functional compound via Menschutkin quaternization reaction. Subsequently, pyrene possessing hyperbranched copolymers were attached onto multiwalled carbon nanotube surface by π-π stacking strategy. Gel permeation chromatog., thermal gravimetric anal. and UV spectroscopy were utilized to analyze structures and mol. weight values of modified copolymers and precursors. Dispersion experiments of resulting copolymers/CNT were also carried out in organic and aqueous media in different pH values. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Category: bromides-buliding-blocks).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Category: bromides-buliding-blocks
