A versatile strategy based on a catalyzed in-situ sol-gel reaction in melt mixing was presented for the fabrication of polypropylene (PP) nanocomposites that equip inorganic network structures. PP nanocomposites with TiO2 network structures were obtained by melt mixing PP powder which was preliminarily impregnated with titanium alkoxide and a catalytic component. The addition of catalytic components, especially hindered amine stabilizer, was found to be effective not only for the acceleration of the in-situ sol-gel reaction but also for improved dispersion of formed inorganic nanoparticles. The obtained PP/TiO2 nanocomposites exhibited the disappearance of the terminal flow at ca. 3 wt% of the TiO2 content, indicative of the network formation. Moreover, the PP/TiO2 nanocomposite films exhibited distinct optical properties: not only high transparency for visible lights due to the excellent dispersion of the made nanoparticles but also absorption of UV lights, where absorption edges were tunable through a quantum effect for nanosized particles. In the experiment, the researchers used many compounds, for example, Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7Electric Literature of C30H56N2O4).
Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7) belongs to piperidine derivatives.Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Several piperidine alkaloids isolated from natural herbs, were found to exhibit antiproliferation and antimetastatic effects on various types of cancers both in vitro and in vivo for example Piperine, Evodiamine, Matrine, Berberine and Tetrandine.Electric Literature of C30H56N2O4
