Distribtion and Precipitation Rate of CIPs in DMF/TPU composites

Composites consisting of magnetic powders and thermoplastic polyurethane elastomer are a uniqueclass of functional materials. In recent years, special attention has been paid to magnetic particles,especially carbonyl iron particles (CIPs), which are usually used due to their excellentelectromagnetic properties. They can be used in various fields of advanced technologies, inbiomedical applications, adsorption and catalytic processes or to produce smart materials. Thedeposition time, speed and volume of CIPs were evaluated in pure dimethylformamide (DMF) andthe different concentrations of dimethylformamide (DMF)/thermoplastic polyurethane (TPU)solutions. The gravitational force on CIPs during the sedimentation process overcome on viscosityof DMF/TPU solution. This article considered to control the distribution of CIPs in thickness of TPUsheets.
