      Organic solvent-soluble N-maleoyl-chitosan (NMCS) was synthesized by reaction of chitosan with maleic anhydride (MAH) in N,N-dimethylformamide (DMF). N-maleoyl-chitosan-graft-poly(N-isopropylacrylamide) (NMCS-g-PNIPAAm) copolymer hydrogel was prepared via free radical polymerization by electron beam (EB) irradiation. The copolymer obtained was analysed by FT–IR, XRD and thermal gravimetric analysis (TGA). It was found that the grafting yield and grafting efficiency increased with increasing radiation absorbed dose and monomer amount, and then decreased. The swelling ratio of the copolymer hydrogel was low at pH 4–5, and LCST of the hydrogel was around 32°C.

      Graphite/thermosetting composites were prepared via a melt blending and compression–curing process using epoxy and phenolic resins as polymer matrices. The flexural strength, flexural modulus and electrical conductivity of thecomposites were investigated. The composites containing 55wt% graphite showed the maximum flexural strength and modulus. Scanning electron microscopy results showed that the thermosetting resins and graphite were uniformly dispersed on the fractured surface of the composites. The electrical conductivity of the composites increased with an increase in the graphite content. The flexural and electrical properties of the composites improved significantly by the addition of a carbon fibre cloth (CFC) or a CFC and carbon nanotubes.
