Functionalized MWCNTs, an efficient reinforcement for the preparation of eugenol based high performance PBz/BMI/CNT nanocomposites exhibiting outstanding thermo-mechanical properties

The chemistry of benzoxazine synthesis offers wide molecular design flexibility and thus facilitates preparation of various polybenzoxazine based composites. In this paper, we reported the preparation of polybenzoxazine/BMI blend and subsequent preparation of nanocomposites with amine functionalized multiwalled carbon nanotubes (F-MWCNTs). The curing mechanism and the material properties of the blend and nanocomposites were studied extensively. DSC analysis showed two exothermic maxima, corresponding to benzoxazine and allyl group polymerization. Furthermore, by the incorporation of F-MWCNTs into the PBz/BMI system, the properties of the PBz/BMI/F-MWCNT nanocomposites were improved significantly. The enhancement in the material properties is due to the strong interaction between the F-MWCNTs and PBz, resulting in the formation of interpenetrating polymer networks. The morphology and fracture surface of the nanocomposites were studied by scanning electron microscopy. The thermal, mechanical and dielectric properties of the nanocomposites are found to be outstanding when compared with the neat PBz and PBz/BMI blend.

Novel diisocyano-based dinuclear gold(I) complexes with aggregation-induced emission and mechanochromism characteristics

A series of constitutional isomers containing dinuclear gold(I) units were designed, synthesized and characterized using IR spectrometry, NMR spectroscopy and elemental analysis. The aggregation-induced emission (AIE) characteristics of the complexes were investigated by photoluminescence (PL) and UV/Vis spectroscopy. The results indicated that gold(I) complexes 1-3 exhibited significant AIE phenomena. PL spectroscopy, used to probe their solid-state mechanochromic properties, suggested ortho-isomer luminogen 1 exhibited reversible mechanochromic fluorescence, whereas meta-isomer luminogen 2 showed switchable mechanical force-induced luminescence enhancement behavior. No mechanochromism behavior was observed for para-isomer luminogen 3. Powder X-ray diffraction indicated that the morphology phase conversion between crystalline and amorphous states is responsible for the mechanochromism or mechanical force-induced emission enhancement characteristics.

METHOD FOR PREPARING A POLY(ETHER SULFONIMIDE OR -AMIDE) COPOLYMER USING CYCLIC OLIGOMERS

Disclosed is a method for preparing a poly(ethersulfonimide or ethersulfonamide) copolymer using cyclic oligomers, and more particularly, to a method for preparing a poly(ethersulfonimide or ethersulfonamide) copolymer by preparing a cyclic ether sulfone oligomer and a cyclic imide or amide oligomer and subjecting the cyclic ether sulfone oligomer and the cyclic imide or amide oligomer to ring-opening copolymerization in the presence of an alkali metal fluoride catalyst.
