Abstract
Acrylonitrile–butadiene–styrene (ABS) composites filled with anhydrous copper sulfate (CuSO4) particles were prepared by planetary ball mill. The ball milling process can provide CuSO4 particles of small sizes for homogeneous particle distribution in a matrix. To directly enhance the interaction between the two ingredients, a coordination reaction was generated by heat press at 180 °C. Fourier transform infrared, electron spin resonance, Ultraviolet–visible, and X-ray photoelectron spectroscopy were employed to investigate the coordination reaction. The results showed that a coordination reaction happened between nitrile groups (–CN) of ABS and copper ions (Cu2+) of CuSO4. The loss factor of dynamic mechanical analysis indicated the decrease of intermolecular friction due to a strong interaction between the matrix and the particles. The homogeneously dispersed, micro-sized CuSO4 particles were observed by scanning electron microscope. The interface was indistinguishable under the microscope indicating a well-bonded surface and good compatibility. In addition, dissolution behavior showed that the solvent resistance of the composites was significantly improved.
