Rheological studies on a novel liquod crystalline epoxy thermost
Liquid crystalline epoxy thermosets were prepared by adding 3,3',5,5'-Tetramethylbiphenyl-4,4'-diyl bis(4-(oxiran-2 ylmethoxy)benzoate) (M1) into diglycidylether of bisphenol A
(DGEBA)/ 4,4'-diaminodiphenyl methane (DDM) blends. Rheological
tests with constant temperature and time tests under constant mechanical shear load conditions were performed by using rheometry instrument.

Polyoxometalate cured epoxy resins with photochromic properties
Novel photochromic thermosetting materials were facile prepared by polyoxometalate, Keggin type H3PW12O40, cured epoxy networks with ethylene oxide blocks. The dual functions of polyoxometalate as both hardener and photochromophore were studied by differential scanning calorimetry (DSC), infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV-vis) and generalized two-dimensional correlati...

Effects of Storage Aging on the Properties of Epoxy Prepregs.
Changes in the properties of epoxy prepregs during storage are of both industrial and theoretical interest. It would be very helpful to have a test, suitable for production use, to determine when a prepreg has aged beyond acceptable limits. In this article, different epoxy prepregs aged under various conditions were studied by near-infrared (NIR) and mid-infrared (MIR) Fourier transform spectrosco...
