Microstructure and interface in organic/inorganic hybrid composites

Effect of nanosilica on the dielectric properties and thermal stability of polyimide/SiO2nanohybrid

“…One way of decreasing the extent of phase separation (increasing the miscibility) is by: (a) functionalizing the oligomers or polymer chains at their ends, (b) selecting polymers with appropriate groups within the repeat units, (c) involving co-monomers possessing appropriate functional groups, or (d) adding a coupling agent that can bond with both the growing inorganic oxide network and the PI chains [21][22][23][24][25][26][27][28][29][30].…”

Fluorescence Spectroscopic and Atomic Force Microscopic Studies on the Microstructure of Polyimide/Silica-Titania Ternary Hybrid Composites

“…Though fluorescence spectroscopy has been also used to investigate the interfacial interaction or miscibility in polymer blends as well as the dynamics and structure of solid polymers, [16][17][18][19][20][21][22] very little has been published on the fluorescence spectroscopic studies of organic/inorganic hybrid composites. Recently, we reported that the fluorescence spectroscopy can provide insight into how the state of organization of the PI matrix is altered by the presence of Si in the PI/Si hybrid composite films.…”

Mechanical and Thermal Characteristics of Bio-Nanocomposites Consisting of Poly-L-lactic Acid and Self-Assembling Siloxane Nanoparticles with Three Phases

“…Metal oxide nanoparticles are typically formed by hydrolysis and condensation reactions of organic metal compounds, mainly silicon alkoxides [10][11][12][13][14] and perhydropolysilazane [15], in solvents or polymers, that is, 2 Journal of Nanotechnology a sol-gel method. However, the formation of multiplephased nanoparticles using these organic metal compounds is difficult due to their limited chemical structures.…”
