PANI‐DBSA particles were synthesized through in‐situ lotion polymerization of aniline (AN) and dodecylbenzene sulfonic acid (DBSA) as raw materials, which followed by combining with epoxy resin (E‐44) and castor oil (CO) to prepare a polyaniline mixture (PANI‐DBSA/CO), which was used as nano filler to create nano polyaniline/polyurethane interpenetrating polymer network(IPN) coating. SEM, XRD, and FTIR were used to characterize the PANI‐DBSA and PANI‐PU interpenetrating network composite coatings that were produced. The coating's physical and mechanical characteristics were investigated, as well as the system's corrosion behavior in 3.5wt% NaCl solution, utilizing electrochemical impedance spectroscopy (EIS) and electrokinetic polarization. Acid, alkali, and salt water immersion investigations were used to further evaluate the coating's medium resistance. The results show that when PANI‐DBSA is added at 1wt%, the contact angle reaches 102.6°, the adhesion reaches S1 grade after 720h immersion, the tensile strength is 16.22MPa and the elongation reaches 208%. The impedance value of the composite coating grew by 569 times with the addition of 1wt% polyaniline, and the resistance duration of 10wt% H2SO4, 10wt% NaOH, and 3.5wt% NaCl reached more than 90 days. The addition of polyaniline to IPN coatings can increase corrosion resistance and extend their application range.This article is protected by copyright. All rights reserved.

“…It is mainly composed of ceramic nanoparticles. To prepare PU materials with both antistatic properties and high strength, Tian et al 20 fabricated PU/polyaniline/silica composite, and 4% polyaniline made the surface resistance of the composite reduce from 1.1 × 10 12 Ω to 7.6 × 10 10 Ω. Compared with pure PU, the addition of silica increased the tensile strength and elongation at the break of the composite by nearly 300% and 100% respectively.…”

Polymer materials have been widely used in modern industries duo to their characteristics such as lightweight, low price, and corrosion resistance. However, the inherent insulation of polymer materials can cause static electricity, which has become one of the major problems that has limited their application. Meanwhile, as the basis for ensuring the service field and life of the polymer materials, mechanical properties can affect the comprehensive properties of the polymer materials. Therefore, research on the preparation of composite materials with both antistatic properties and good mechanical properties with antistatic-reinforced modification has attracted extensive attention and achieved important progress. Based on the principle of electrostatic electrification of antistatic-reinforced modification, antistatic mechanisms and main preparation strategies, this paper summarized the research achievements of the antistatic-reinforced polymer materials in recent years. Additionally, some factors that have affected their antistatic properties were presented, and the development trends of the antistatic-reinforced polymer materials based on the deficiencies of current research were proposed.

“…High specific area of CP composites and combination of excellent electrical, electrochemical and optical properties of CPs and mechanical strength and binding characteristics of polymer-based matrix makes them an excellent choice for lots of applications [ 23 ]. Due to elastomeric properties of PU, these materials became stretchable electronics and can also be engineered to be useful in applications in many areas such as high-performance sensors [ 24 ], tissue engineering [ 25 ], rechargeable batteries [ 26 ], supercapacitors [ 27 ], corrosion-inhibiting [ 28 ], antistatic coatings [ 29 ], fuel cells [ 30 ], EMI shielding materials [ 31 ], biomedical applications [ 32 ], wearable textiles [ 33 ] desalination [ 34 ] and so on. They have been reported that the fabricated composites displayed a good electroactivity and high porosity and specific surface area.…”

In this study, single-side polypyrrole (PPy) coated conductive stretchable polyurethane (PU) / PPy composite films were synthesized by chemical oxidative method in the acetonitrile (ACN)/H 2 O interface as a new alternative to two-side coated PU films which have already reported in the literature. One surface of the PU film was contacted with aqueous Py solution and the other surface with cerium ammonium nitrate (CAN) solution in ACN, so that only one surface of the film was coated with PPy and the resulting composite was named PU/PPy (PUP). This composite was characterized by four-point probe conductivity measurement, Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) measurements, and mechanical testing. The thickness of PPy coating was determined as 16 μm, by using polarized microscope imagines of crosssection of film. T g value of the composite was obtained as −60.38 °C and the highest conductivity of PPy coated side of PU was obtained as 3.5 × 10 −4 S cm −1 , while the back side of PU film was still insulator.
