Hydrophobic Modification of Layered Clays and Compatibility for Epoxy Nanocomposites
Recent studies on the intercalation and exfoliation of layered clays with polymeric intercalating agents involving poly(oxypropylene)-amines and the particular uses for epoxy nanocomposites are reviewed. For intercalation, counter-ionic exchange reactions of clays including cationic layered silicates and anionic Al-Mg layered double hydroxide (LDH) with polymeric organic ions afforded organocla...

MODIFICATION OF CLAYS WITH IONIC LIQUIDS FOR POLYMER NANOCOMPOSITES by Neung Hyun Kim In attempts to prepare nanofillers with enhanced compatibility with a polymer matrix, cationic and anionic clays susceptible to exchange of their interlamellar ions with a variety of other cations or anions, were selected. In order to treat cationic clay, montmorillonite, which contains sodium ions as interlay...
متن کاملProperties of Epoxy/SiO2 - and Epoxy/ZrO2 - Nanocomposites
The synthesis, structure and mechanical properties of inorganic organic nanocomposites are investigated: The systems consist of an aliphatic amine cured Bisphenol-F-based epoxy resin as organic matrix and SiO2 and ZrO2 nanoparticles as inorganic fillers. Silica and zirconia nanoparticles have been prepared in two different size ranges, one in the upper nano range (30-60 nm) and other in the low...
متن کاملPreparation of clay/epoxy nanocomposites by layered-double-hydroxide initiated self-polymerization
An anionic clay, magnesium–aluminum layered double hydroxide (Mg2Al–NO3–LDH), was prepared by a co-precipitation method and intercalated with poly(oxypropylene)–amindocarboxylic acid (POP– amido acid). Depending on the POP-intercalating agents with molecular weight at 2000 or 400 g/mol, the intercalated LDHs were analyzed to have d spacing of 6.8 or 2.7 nm and organic incorporation of 80 and 55...
متن کاملCellulose whisker/epoxy resin nanocomposites.
New nanocomposites composed of cellulose nanofibers or "whiskers" and an epoxy resin were prepared. Cellulose whiskers with aspect ratios of approximately 10 and approximately 84 were isolated from cotton and sea animals called tunicates, respectively. Suspensions of these whiskers in dimethylformamide were combined with an oligomeric difunctional diglycidyl ether of bisphenol A with an epoxide...
