Thermosetting terpolymer composed of benzoxazine (BA-a), cyanate ester (BADCy) and epoxy resin (E44) was prepared via co-curing reactions. The curing procedure for the ternary blend studied by differential scanning calorimetry (DSC) Fourier transform-infrared spectroscopy (FT-IR), thermal, mechanical dielectric properties were also characterized. DSC results manifested a multiple pattern, suggesting complexity reactions in system. FT-IR analysis further showed that involves several steps,...

To overcome the brittleness of polybenzoxazine and decrease its high curing temperature, sulfonated polysulfone/polysulfone/benzoxazine ternary blends were prepared, their behaviors, phase structures properties probed. Sulfonated polysulfone (SPSU) was synthesized firstly, then SPSU applied to modify 4,4′-diaminodiphenyl methane based benzoxazine (BZ-m) along with polysulfone. The results obtained from differential scanning calorimetry showed that addition efficiently decreased temperature...
Silver nanosheets with a nanogap smaller than 10 nm and high reproducibility were constructed through simple environmentally friendly electrodeposition method on copper plate. The sizes of the nanogaps can be varied from around 7 to 150 by adjusting deposition time current density. different exhibited surface-enhanced Raman scattering (SERS) properties due electromagnetic mechanism (EM). optimized density silver showed effective SERS ability an enhanced factor as 2.0 × 10(5). Furthermore,...
The kinetic and calorimetric fragility indices m of binary As–Se Se–Te chalcogenide liquids with a wide range are determined using combination parallel plate rheometry, beam bending viscometry, conventional differential scanning calorimetry (DSC). It is shown that both sets measurements lead to consistent values only if the validity assumptions often implicit in methodology for estimation considered. These (i) glass transition temperature Tg corresponds viscosity ∼1012 Pa s (ii) enthalpy...
A modified benzoxazine resin system with “high strength, high modulus and toughness” was prepared by introducing an efficient modifier (<italic>m</italic>-DHPBP) catalytic activity aryl-ether-ether-ketone (PEEK) structure.
