“…In comparison with that of pristine DABA-Ph, the copolymerization between allyl moieties and BMI would increase the steric hindrance during the polymerization process of nitrile groups. The active hydrogen would be partly involved into the addition reaction of BMI [25,26]. Thus, the polymerization rate and degree of nitrile groups would weaken accordingly with increasing the content of BMI.…”

Copolymerization is the typical method to obtain the high-performance resin composites, due to its universality and regulation performance. It can be employed among various resin matrices with active groups to obtain the desired structures, and subsequently, the outstanding properties. In this work, the copolymerization between the allyl-functional phthalonitrile-containing benzoxazine resin (DABA-Ph) and 4,4′-bis(Maleimidodiphenyl)methane (BMI) were monitored. The interactions among the active groups including allyl moieties, maleimide, benzoxazine rings and nitrile groups were investigated. Differential scanning calorimetry (DSC) and dynamic rheological analysis (DRA) were used to study the curing behaviors and the processing properties. The possible curing processes were proposed and confirmed by Fourier transform infrared spectroscopy (FTIR). Then, glass fiber-reinforced DABA-Ph/BMI composites were designed, and their thermal-mechanical properties were studied. Results indicated that all the composites exhibited outstanding flexural strength, flexural modulus, and high glass-transition temperatures ( T g > 450 °C). The thermal stability of the composites was studied by thermogravimetry (TGA) and evaluated by the integral program decomposition temperature (IPDT). it is believed that the excellent thermal mechanical properties and outstanding T g as well as good thermal stability would enable the reinforced copolymer-based laminates to be applied in wider fields.

Graphene oxide was obtained by improved Hummers method. Hydrated hydrazine, chitosan or potassium hydroxide was used to prepare different reduced graphene oxide (rGO) in order to choose the best reductant, respectively. The rGO was restored and modified by ionic liquid (NH 2 IL) to obtain functionalized graphene (NH 2 IL-rGO), the matrix (MBAE) was synthesized from 4,4′-diamino diphenyl methane bismaleimide modified by diallyl bisphenol A and Bisphenol A bisallyl ether. NH 2 IL-rGO/MBAE composites were prepared from NH 2 IL-rGO and MBAE via in situ polymerization, and also studied the effect of NH 2 IL-rGO on the properties of composites. The results showed that the micro-morphology of composite existed twophase structure between the matrix and NH 2 IL-rGO, which gave the material excellent properties. The impact strength and bending strength of the composite reached the maximum and were 15.33 kJ/m 2 and 142 MPa, respectively, when the content of NH 2 IL-rGO was 2 wt%. The thermal decomposition temperature of the composite was 435 °C, the dielectric constant of the composite abruptly reached 84 in the frequency range 10 2 ~ 10 5 Hz.

Graphene oxide (GO) as an excellent nanofiller is widely used to improve the mechanical properties of the resin matrix. The dispersion and distribution of GO sheets in the resin matrix have a strong impact on the mechanical properties of composites. Based on the action principle of GO sponge, a simple method for solving the highly and aligned dispersion of GO in the bismaleimide (BMI) resin is investigated. The GO bulk prepared by vacuum infusion using a porous GO sponge as a frame is smashed in the resin by the large shear force generated through the high‐speed stirring method. It is found that GO sheets have a highly dispersion in the BMI resin. A sample and new method for preparing GO aligned dispersion in resin by large deformation is provided to further enhance the mechanical properties of the resin. As expected, the flexural strength and flexural modulus of GO/BMI nanocomposites are enhanced by 39.6% and 45.5% than BMI resin. This simple dispersion method is easier to generalize to solve the dispensability of GO in other kinds of resins. In the future, there will be a broader application prospect in engineering applications.
