Properties and structure of cyanate ester/polysulfone/organoclay nanocomposites

Novel high‐performance wave‐transparent aluminum phosphate/cyanate ester composites

“…12,13 To date, some inorganic filler/CE composites have been studied such as aluminum borate whisker/CE, carbon nanotube/CE, polyhedral oligomeric silsesquioxane/CE, and polysalfone/CE, [14][15][16][17] and results have proved that these composites have better thermal properties than original CE resin. On the other hand, the effect of inorganic fillers on the dielectric properties of polymeric matrices has been investigated, 18,19 and results suggest that dielectric properties of inorganic/CE composites are greatly depended on that of inorganic materials.…”

Effect of nanoclay on the mechanical, dynamic mechanical and thermal properties of cyanate ester syntactic foams

“…This further supports the fact that matrix plasticization is responsible for reduction in storage modulus and T g in the present study. A small decrease in T g is observed for BACY by the addition of the nanoclay, Nanofil 919 [22].…”

“…Tensile properties of syntactic foams are normally dependent on the properties of the matrix used and microballoon-matrix interfacial strength [1,22]. The increase in tensile strength of cyanate ester syntactic foams by nanoclay addition is due to the presence of exfoliated/intercalated nanoclay particles which provides high surface area of interaction with the matrix.…”

Clay-Containing Polysulfone Nanocomposites

“…A blend composed of PSf, cyanate ester and organophilic MMT was prepared by melt intercalation. Although the flexural modulus was not significantly modified, thermal stability fracture toughness and fracture energy were improved in comparison with the two matrixes due to the good adhesion level of PSf particles to the matrix as well as the homogenous dispersion of the clay mineral platelets into the system (Mondragón et al, 2006). In 2006, polysulfone nanocomposite membranes were again prepared by solution dispersion in NMP by using an unmodified (Cloisite Na) and organically modified (Closite 30B and 93) clays.…”
