Waterborne acrylic–polyaniline nanocomposite as antistatic coating: preparation and characterization

An antistatic and electrically conductive acrylic–polyaniline nanocomposite coating was successfully synthesized by interfacial polymerization of aniline in the presence of acrylic latex. The acrylic latex was prepared through emulsion polymerization, and aniline was polymerized by in situ interfacial polymerization at the interface of acrylic latex/chloroform phase. Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy and CHNS elemental analysis revealed the existence of 6.24 wt% emeraldine salt of polyaniline (PAni) in the dried film of the nanocomposite. Scanning electron microscopy (SEM) confirmed the presence of colloidal polymer particles in the aqueous phase which was confirmed to have some advantages, including prevention of aggregation of particles, dispersibility improvement and enhancement of the PAni nanofibers aspect ratio in the acrylic polymer matrix. According to SEM results, PAni fibers with the length ranging from 12 to 67 µm and diameters between 0.078 and 1 µm, highly dispersed in the acrylic polymer matrix, were successfully synthesized. Thermal, electrical and mechanical properties of the acrylic copolymer were significantly affected by PAni incorporation. The onset degradation temperature in thermogravimetric analysis revealed that the thermal stability of the nanocomposite was improved compared to that of the pure acrylic copolymer. The nanocomposite film showed electrical conductivity of about 0.025 S/cm at room temperature, along with satisfactory mechanical properties, attractive as an antistatic material in coating applications.

Preparation and properties of poly(ether‐ester‐amide)/poly(acrylonitrile‐co‐butadiene‐co‐styrene) antistatic blends

A novel antistatic agent poly(ether‐ester‐amide) (PEEA) based on caprolactam, polyethylene glycol, and 6‐aminocaproic acid was successfully synthesized by melting polycondensation. The structure, thermal properties, and antistatic ability of the copolymer were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analyses, and ZC36 megohmmeter. Test results show that PEEA is a block copolymer with a melting point of 217°C and a thermal decomposition temperature of 409°C, together with a surface resistivity of 10⁸ Ω/sq. Antistatic poly(acrylonitrile‐co‐butadiene‐co‐styrene) (ABS) materials were prepared by blending different content of PEEA to ABS resin. The antistatic performances, morphology, and mechanical properties were investigated. It is indicated that the surface resistivity of PEEA/ABS blends decrease with the increasing PEEA content, and the excellent antistatic performance is obtained when the antistatic agent is up to 10–15%. The antistatic performance is hardly influenced by water‐washing and relative humidity, and a permanent antistatic performance is available. The antistatic mechanism is investigated. The compatibility of the blends was studied by scanning electron microscopy images. The ladder distribution of antistatic agent is formed, and a rich phase of antistatic agent can be found in the surface layer. The elongations at break of the blend are improved with the increasing antistatic agent; the tensile strength and the notched impact strength kept almost the same. © 2011 Wiley Periodicals, Inc.

The investigation of antistatic effects of 1-ethyl-2,3-dimethylimidazolium ethyl sulphate for acrylic-based polymer film

This study aims to produce a long-term antistatic acrylic-based film by incorporating ionic liquid (IL), 1-ethyl-2,3-dimethylimidazolium ethyl sulphate (EIL) into acrylic resin. After loading, characterisations of samples were conducted by mechanically, thermally and morphologically. In order to determine antistatic properties, surface resistivity of samples was measured by using at different time intervals. The results indicated that IL loaded polymers showed a good antistatic property for a long time. The effect of incorporation on tensile strength, tensile modulus, flexural strength and flexural modulus of polymer were also obtained. After loading process, tensile strength, tensile modulus, flexural strength and flexural modulus values decreased considerably. The decrement in tensile strength of polymer is much less than that in flexural strength. The effect of EIL incorporation into acrylic resin on thermal conductivity and surface wettability was also investigated. From scanning electron microscopy images, EIL particles in nano-size range were observed in polymer structure.     

Enhanced antistatic and solvent resistant polycarbonate blends: Fabrication and characterization

This study presents the development of advanced antistatic and solvent resistant polycarbonate blends by incorporating antistatic agents (AAs) into bisphenol A-type polycarbonate (PBPA) and polycarbonate-polysiloxane copolymer (P-Si). A straightforward one-step melt blending was employed to fabricate PBPA/P-Si/AA blends. Comprehensive characterization methods, including Fourier-transform infrared spectroscopy (FT-IR), optical microscope, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and both tensile and impact tests were deployed to study the structure, morphology, thermal, and mechanical behaviors of the synthesized blends. The results demonstrated effective mixing of PBPA and P-Si. The T_g of PBPA/P-Si/AA blends is decreased relative to PBPA, because the chain flexibility of the blends will be increased after adding AA, which is reflected in the impact strength and elongation at break of PBPA/P-Si/AA blends. On the other hand, the thermal stability of PBPA/P-Si/AA is reduced relative to PBPA. The most significant result is that the resistance of the blends to ethyl acetate is enhanced. This is because the addition of P-Si to the matrix introduces a high bonding energy Si O bond, which makes PHBPA/P-Si less prone to detachment and cracking and swelling when exposed to ethyl acetate. While improving the solvent resistance, the blends also have excellent antistatic property, only the concentration of AA is increased to 6 wt.%, and the surface resistance of PBPA/P-Si/AA is reduced from 10⁶ GΩ to only 1 GΩ. This dramatic decrease is a result of the widespread distribution of the positive charge of the ammonium ion throughout the material, promoting the formation of a continuous conductive network within the matrix and thereby enhancing conductivity. In conclusion, this study offers valuable insights into improving the solvent resistance and antistatic characteristics of polycarbonate blends.
