“…The diameter of the P/Z composite was between 300 and 600 nm, which may be due to the accumulation of single PANI chains released from the zeolite layers (Fig. 3c); it has been reported that one zeolite layer contains many PANI chains [28,32].…”

Reverse osmosis desalination water plants have several operational issues such as corrosion in many areas like energy recovery devices that are accustomed to restore energy and scale back prices. Thus, there is a necessity to reduce the corrosion rate of the devices utilized in energy recovery. This study focuses on protection of some metals and alloys that are utilized in this industry by introducing a new anticorrosion coating. The new anticorrosion coating was formulated by the interaction of polyaniline and X-type zeolite that is employed as hosting material. Polyaniline was first formulated by conventional oxidation polymerization method of aniline in acidic medium at temperature below 5 °C by using ice bath. Then, ammonium persulphate was used as oxidizer. Numerous characterization techniques were used to demonstrate the encapsulation of polyaniline in X-type zeolite frames such as IR, UV-visible spectroscopy, scanning electron microscopy, transmission electron microscope, energy-dispersive X-ray and X-ray diffraction. The new anticorrosion coating was evaluated by using weight loss technique, Tafel polarization and electrochemical impedance spectroscopy; all of these techniques showed the effective anticorrosion properties of the prepared coating in which the corrosion rate from the polarization curves results, for all coated samples, was less than the bare ones as it recorded 2.403, 1.094, 23.48, 35.09 MPY for bare 304 and 316 stainless steel, Al and carbon steel, respectively, and 0.3132, 0.2733, 0.2506, 10.81 MPY for the coated samples. Corrosion results showed a noteworthy protection of the tested metals and alloys in saline water coated with the polyaniline/zeolite X.

“…As an electrically conductive polymer, polyaniline (PANI) has attracted considerable interest for several decades. Tremendous research has been done to improve the conductivity and processability of PANI by forming interpenetrating polymer networks (IPNs), copolymers, composites, and blends 1–8. This report concerns the synthesis and characterization of PANI/crosslinked polyvinylacetate (PVAc) semi‐IPNs.…”

Electrically conductive semi-IPNs based on polyaniline and crosslinked polyvinylacetate were prepared. Polyaniline successfully percolated through the crosslinked PVAc networks and the resulting semi-IPNs show a continuous network morphology. The conductivity of the semi-IPN increases with increasing content of polyaniline and increasing acidity used during the polymerization of the polyaniline. The conductivity of the semi-IPN is 0.13 S/cm, with the highest polyaniline content of 19.3 wt %. The depression of polyaniline with temperature change is smallest followed by the depression of semi-IPN of the polyaniline/crosslinked polyvinylacetate, which is considerably smaller than the depression of crosslinked polyvinylacetate.

Polyaniline (PANI) composites containing poly(3-hydroxybutyric acid) (PHB) were synthesized via in situ deposition technique. The oxidative polymerization of aniline hydrochloride was carried out by dissolving different weight percentages (10 wt%, 20 wt%, 30 wt%, 40 wt%, and 50 wt%) of PHB using ammonium persulfate as an oxidant. The as-synthesized composites were characterized using Fourier-transform infrared spectroscopy and X-ray diffraction pattern. The surface morphology of the resulting composites was studied using transmission electron microscopy. The temperature-dependent direct current conductivity of the synthesized composite films was measured, and the activation energy responsible for the conductivity was examined. Incorporation of the biodegradable polymer, PHB, during the preparation of new PANI composites significantly increased the conductivity of the resulting composites. POLYM. COM-POS., 34:1655-1662
