“…For the spectrum of PAI/PANI/CB ternary blend composites, the N–H vibration of the amide group was further blue shifted to 3289 cm −1 , indicating that the hydrogen bonding interaction of polar groups in the ternary blend composites was strengthened. It is believed that the hydrogen bonding interaction in the PAI/PANI/CB ternary blend composites is helpful in breaking the intermolecular force in the CB and enhancing the interfacial adhesion among PAI, PANI, and CB, which is beneficial for the improvement in conductive and mechanical performances [60].…”

Highly conductive thin films with suitable mechanical performances play a significant role in modern electronic industry. Herein, a series of ternary conductive polymer composites were fabricated by incorporating carbon black (CB) into binary conductive polymer composites of poly(amide-imide) (PAI) and polyaniline (PANI) to enhance their mechanical and conductive properties simultaneously. By varying the composition of PAI/PANI/CB ternary films, the conductivity enhanced by two orders of magnitude compared with the sum of PAI/PANI and PAI/CB binary conductive polymer composites, and a high conductivity of 1160 S m−1 was achieved. The improved conductivity is mainly because much more continuous conductive networks were constructed in the ternary conductive polymer composites. With the help of the unusual morphology, the tensile strength was also enhanced by more than 80% from 21 to 38 MPa. The origin for the improved morphology was discussed for further improvement.

“…In fact, it is very necessary to investigate the thermal degradation process of composites, because the flame retardancy and processability of polymers in practice are closely related to their thermal stability. Because their products have good physical and mechanical properties, chemical resistance, and electrical insulation, 4,4′-diamino-diphenyl methane (DDM) and diglycidyl ether of bisphenol A (DGEBA) have become two important monomers in EP industrial production. − In this study, they were used as raw materials to prepare bisphenol A-type EP. Polyepoxyphenylsilsesquioxane (PEPSQ) is a reactive flame retardant, which can be chemically bonded with the main chain of EP.…”

Polyepoxyphenylsilsesquioxane (PEPSQ) and diethyl bis(2-hydroxyethyl) aminomethylphosphonate (DBAMP) can improve the flame retardancy of epoxy resin (EP). In this paper, the results of the limiting oxygen index (LOI) and UL94 tests exhibited that PEPSQ and DBAMP had good synergistic flame retardancy. The non-isothermal degradation kinetics of EP containing PEPSQ and DBAMP was investigated by the Kissinger and Flynn−Wall−Ozawa methods. The results of the Kissinger method displayed that the addition of two flame retardants, PEPSQ and DBAMP, can slightly enhance the activation energy of EP, indicating that the additives delayed the thermal degradation of EP. The Flynn−Wall−Ozawa method further confirmed that the activation energy of EP during the whole thermal degradation process can be significantly increased by addition of the two flame retardants PEPSQ and DBAMP. When the degree of conversion exceeded 80%, the increase was more significant. This illustrated that the flame retardants finally achieved the purpose of improving the flame retardancy of EP by stabilizing the char layer.

[11][12][13][14][15] CTBN has reactive carboxyl end groups, and these can efficiently react with the epoxy resins.

Epoxy resins, despite their unique properties, have limitations in many applications due to their low fracture toughness. One of the most effective methods to overcome this limitation is to use toughening agents, such as carboxyl terminated poly butadiene-acrylonitrile (CTBN) in the epoxy matrix. CTBN can react with various compounds, such as epoxies. In this study, we investigated the severity of CTBN sedimentation with di epoxy octane (DEO) in the presence basis catalysts. The studied of the physical properties of the synthesized copolymer in the presence of pyridine compared to other catalysts increases mechanical properties (248.43% elongation, 0.63 MPa strength, and 32 hardness with Shore A) and decreases the glass transition temperature (−45.1) of the copolymer. Investigated the cure kinetics of the CTBN-DEO reaction was in the presence of pyridine using a nonisothermal technique of differential scanning calorimetry, and the curing kinetic parameters, such as activation energy (E a), pre-exponential factor (A), and rate constant (k), were calculated by different kinetic methods. The obtained curing kinetic values with different kinetic methods are well-matched, the E a values are in the range of 91.3-97.1 kJ.mol −1 and the A values are in the range of 0.48 × 10 11-1.51 × 10 11 S −1 .
