Synthesis and properties of polypropylene-graphene nanocomposite was written by Rishaban, R.;Balakrishnan, G.;Hema, R.. And the article was included in Materials Today: Proceedings in 2022.Category: esters-buliding-blocks This article mentions the following:
Graphene being 2D crystalline material has attracted broad and deep interest all over the world due to its good phys., chem., mech. and elec. property with high shape asymmetry. Fabrication of high-quality graphene is becoming increasingly important to work on its various properties and application prospects. Recent progress on the hybrid material-based nanomaterial has greater prospects in many applications. In this investigation, com. graphite powder is preferred as the precursor and two different solvents showing different exfoliation efficiencies, i.e., N-Methyl-2-pyrrolidone and 1-Methylnaphthalene are employed as exfoliation media. Ball milling technique, known to have successfully produced nanomaterials in large scale, is employed in this work to produce multi- layered graphene sheets. Multi-layer graphene’s are made with high aspect ratio with modifications in process parameter. The exfoliated multi-layered graphene is incorporated as filler material with polypropylene matrix to develop polymer nanocomposites. The enhanced mech. stability of the polypropylene/graphene nanocomposite and its resp. morphol. is studied in this work which has applications in photovoltaics, electronic devices and facial reconstruction. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Category: esters-buliding-blocks).
2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: esters-buliding-blocks
