Interfacial Chemical Oxidative Synthesis of Multifunctional Polyfluoranthene
A novel polyfluoranthene (PFA) exhibiting strong visual fluorescence emission, a highly amplified quenching effect, and widely controllable electrical conductivity is synthesized by the direct cationic oxidative polymerization of fluoranthene in a dynamic interface between n-hexane and nitromethane containing fluoranthene and FeCl3, respectively. A full characterization of the molecular structure ...

Surface modification of polyacrylonitrile fibers for superabsorbent fibers
关键字：superabsorbent fibers,hydrolysis,crosslinking,absorbency
Superabsorbent fibers based on polyacrylonitrile (PAN) fibers were studied. To achieve superabsorbent fibers, PAN fibers were hydrolyzed by sodium hydroxide (NaOH), and then crosslinked by glutaraldehyde. Fourier transform infrared spectroscopy (FTIR...

Continuous Nanoscale Carbon Fibers with Superior Mechanical Strength
关键字：Carbon fibers
Carbon fibers possess high strengths (3-7 GPa), high moduli (200-500 GPa), and low densities (1.75-2.00 g/cm3). The high strength-to-weight ratio combined with superior stiffness has made carbon fibers the material of choice for high&n...

Water Soluble Carboxymethylcellulose Fibers Derived from Alkalization-etherification of Viscose Fibers
Carboxymethylcellulose (CMC) fibers have been successfully prepared from viscose fibers through the process of alkalization-etherification. Parameters including reaction temperature, mass ratio of NaOH to the viscose fibers, and mass ratio of the viscose fibers to ethanol are studied. The degree of substitution (DS) and the inherent viscosity of the CMC fibers are determined. The C...
