Novel Nanosized Aluminium Carboxylates: Synthesis, Characterization and Use as Nanofillers for Protective Polymeric Coatings

“…Our group accomplished this task in a heterogeneous hydrolytic condensation (HHC) reaction. [7][8][9][10][11] Notwithstanding the practical applications of the HHC route, [11,12] its further development was urgently needed for various reasons. Firstly, purification of the acrylic nanodispersions from precarious by-products such as alcohols and alkyl acrylates required considerable technological effort and, secondly, the HHC nanodispersions could only be processed by tempered roll applications (typically at temperatures around 40 8C), particularly eluding spray and dip applications.…”

Comparative study on the optical, surface mechanical and wear resistant properties of transparent coatings filled with pyrogenic and colloidal silica nanoparticles

“…As reported in Ref. [20], for nanosilica particle, higher density corresponds to higher hardness and modulus. Therefore, in this work the real density of the nanoparticles was measured.…”

“…For example, Zhou et al [18,19] indicated that for a given particle content, the pyrogenic nanosilica-filled coating showed lower weight loss than the colloidal nanosilica-filled coating after abrasion wear tests. Bauer et al [20] presented that coatings filled with pyrogenic silica nanoparticles behaved further enhancement in microscratch hardness than those filled with colloidal nanoparticles. They assumed that the density and hardness of pyrogenic nanoparticles were much higher than those of colloidal ones.…”

Isothermal Crystallization of Poly(ethylene-co-glycidyl methacrylate)/Silica Nanocomposites

“…[17][18][19] The mixture was sonicated for 2 h. The modified silica (A-Silica) was separated using a centrifuge and dried at 50 C under vaccum for 6 h.…”

“…For the modified silica nanoparticles, two additional peaks are found at À57:6 and À68:6 ppm. 18,19 Figure 1c shows a 13 C NMR spectrum of neat APTS (dissolved in CDCl 3 ) and Figure 1d shows a 13 C CP MAS NMR spectrum of A-Silica. In Figure 1d, three peaks were observed around 9.8, 24.5 and 45.9 ppm, which could be assigned to C1 0 , C2 0 and C3 0 .…”
