Introduction. Since Helminiak et al.' and Takayanagi2 first proposed the concept of a molecular composite, considerable remarch has been directed a t developing these materiale.3 Conceptually, molecular compitea are mixtures of a rigid rod polymer homogeneously dispersed in a flexible coil polymer matrix, thus providing fiber reinforcement at a molecular level. In practice, however, miscible bl...

The tensile properties of sulfonated polyoxadiazoles have been studied as a function of molecular weight and sulfonation level. All sulfonated polyoxadiazoles synthesized through a polycondensation reaction of the hydrazine sulphate salt and a dicarboxylic acid in poly(phosphoric acid) exhibit rigid-ductile behavior with high Young’s modulus (3-4 GPa) and with larger elongations at break (up to...

the muscle-like technology would be of enormous advantages for biomedical applications such as medical implants and human assist devices. ionic polymer metal composites (ipmcs) are one kind of biomimetic actuators. an ionic polymer metal composite composed from an ionomer with high ion exchange capacity that packed between two thin metal layers. in the present study we focused on the preparatio...

Two sulfonated resorcinarenes were synthesized by reacting C-tetra(butyl) resorcinarene or C-tetra(2-(methylthio)ethyl)resorcinarene with formaldehyde in the presence of sodium sulfite. Their structures were determined via FT-IR, 1H-NMR, 13C-NMR and mass spectrometry. Thermal gravimetric analyses of the derivatives were also carried out and revealed the presence of water molecules in the solid ...

A series of novel glycol-clusters containing sulfonated N-acetyl-D-glucosamine (GlcNAc) have been synthesized using click chemistry. Three dendrimers with aromatic dendrons were synthesized using chlorination, azidation and click chemistries. The resulting dendrimers were modified with azide-terminated sulfonated GlcNAc using click chemistry. The sulfonated dendrimers showed affinity for protei...

Sulfonated cellulose beads were prepared by oxidation of Cladophora nanocellulose to 2,3-dialdehyde cellulose followed by sulfonation using bisulfite. The physicochemical properties of the sulfonated beads, i.e., high surface area, high degree of oxidation, spherical shape, and the possibility of tailoring the porosity, make them interesting candidates for the development of immunosorbent platf...
