Quality Control of 3-(4-Aminophenoxy)anilineIn 2015, Liu, Changwei;Qu, Chunyan;Wang, Dezhi;Feng, Hao;Liu, Ping;Zhang, Yang published 《Preparation and characterization of magnetic polyimide composite films copolymerized with aminophthalocyanine-coated Fe3O4 nanocrystals》. 《Journal of Materials Science: Materials in Electronics》published the findings. The article contains the following contents:
Iron-aminophthalocyanine-coated Fe3O4 hybrid nanospheres were synthesized by a one-step solvent-thermal method and followed by a catalytic hydrogenation route. To effectively utilize the excellent magnetic sensitivity of the functional aminophthalocyanine/Fe3O4 hybrid nanospheres, we have developed a novel series of flexible Fe3O4@polyimide (PI) composite films, which was prepared with various Fe3O4/FePc-NH2 nanoparticle loadings (7, 15, 27 and 40 wt%). All of the flexible thin films have uniform morphol. without any agglomeration, which had been confirmed by the anal. of scanning electron microscope images. The above composite films, which have the higher saturation magnetization compared with that of the corresponding pure Fe3O4/PI films, illustrate that the excellent compatibility and homogeneous dispersion of the amine-coated Fe3O4 particles in the PI matrix based on the strong chemisorptions of PI onto the Fe3O4 surfaces and polymerization reactions between the amine groups and anhydride groups could significantly affect the magnetic properties of nanocomposite materials. The observed enhanced thermal stabilities, dramatic increased storage modulus and increased glass transfer temperatures (Tgs) of the magnetic films with increasing the particle loadings indicate that the composites could be a candidate to be used as high-performance absorbing materials.3-(4-Aminophenoxy)aniline (cas: 2657-87-6) were involved in the experimental procedure.
3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Quality Control of 3-(4-Aminophenoxy)anilineEthers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.
