Polyimide/sepiolite nanocomposite films: Preparation, morphology and properties

Effects of sepiolite clay on degradation and fire behaviour of a bisphenol A-based epoxy

“…Its structure is formed by two layers of silica tetrahedrons linked by a layer of magnesium ions in octahedral coordination. The octahedral sheets are not continuous like in the other phyllosilicates: this structure provides infinite channels along the fibre axis with a cross section of about 1 Â 0.4 nm 2 [9,10]. The presence of these channels strongly increases the specific surface area of these particles, up to 200-300 m 2 /g.…”

“…Sepiolite clay is typically characterised by a needle-shaped geometry having nominal dimensions of about ten nanometers in diameter and few microns in length [9]. Fig.…”

“…The presence of these channels strongly increases the specific surface area of these particles, up to 200-300 m 2 /g. By using this large specific surface area, sepiolite clay is used in rheological, sorptive and catalytic applications [9].…”

A facile fabrication of light diffusing film with LDP/polyacrylates composites coating for anti-glare LED application

“…Surface modification of particles [29][30][31] and in situ polymerization [32][33][34][35] are reported to effectively obtain composite with particles homogeneously dispersed in matrix. To investigate the influence of the pretreatment of the LDP, FTIR was used to characterize the structure changing of LDP before and after pretreatment as illustrated in Fig.…”

Polymer/organosilica nanocomposites based on polyimide with benzimidazole linkages and reactive organoclay containing isoleucine amino acid: Synthesis, characterization and morphology properties

“…Various combinations of PIs with inorganic fillers including silica, a layered silicate such as montmorillonite or mica, aluminum nitride, titania, barium titanate and carbon nano-tubes have been reported. The prepared hybrid materials show outstanding thermal stability, mechanical strength and physical properties [13,14]. Recently PIs-silica hybrid materials have received considerable attention, because they often exhibit superior physical, mechanical and thermal properties to conventional mineral-filled composites or unfilled polymers.…”
