“…With the increase in sample temperature, trap distribution shifts to the left and peak trap density decreases. Higher temperature results in thermal activation and easy detrapping of the carriers [22]. Also, carrier mobility is enhanced at higher temperatures.…”

The performance of low-density polyethylene (LDPE) clay nanocomposites was analysed. The inclusion of nano montmorillonite (MMT) clay in LDPE material has significantly increased the contact angle, corona ageing resistance, water droplet initiated corona inception voltage and surface discharge inception voltage of the composites. The surface charge decay rate of the samples significantly reduced on the inclusion of clay indicating modified trap distribution characteristics due to the inclusion of the filler. Dynamical mechanical analysis indicates increased storage modulus and reduced tan (δ) due to nanofillers inclusion. Laser-induced breakdown spectroscopy indicates that on inclusion of nanofillers the plasma temperature increases and crater depth decreases. In particular, increased discharge resistance, improved thermomechanical properties are observed with LDPE-MMT clay composites compared to pure LDPE.

“…Corona/ion discharging, tribo charging, and ozone charging are among these methods. The charge decay on insulating materials can be monitored and quantified using different techniques, such as a Faraday cup, and surface potential measurement techniques, such as Kelvin probe force microscopy (KFPM) and electrostatic probes 13–20 . Most reported literature on polymeric materials have studied the effect of humidity on charge decay as a function of surface and volume resistivities 21–24 .…”

The feasibility of measuring the surface potential decay of polystyrene (PS) film is investigated at room temperature by using Kelvin probe force microscopy (KPFM). The PS film was charged by an ion injection method utilizing Bruker's atomic force microscope (AFM) Nanoman module with a pulse duration of 1 ms, SCM‐PIT electrically conductive probe, and a voltage pulse of −250 mV. The surface potential decayed linearly on a semi‐log scale with time, where the time decay constant was quantified for relative humidity (RH) = 5% by KPFM at room temperature. The surface potential decayed due to the interaction of the PS film with the hydronium ions available in the environment. Furthermore, the effect of the material forms (film vs. microspheres) on the time decay constant at RH = 5% was investigated. The time decay constants measured using different methods exhibited excellent correlation with the AFM‐KPFM. This also confirmed that the results are independent of the material form (microspheres vs. film form). As a result, the proposed method can be used to measure the effect of RH for any PS surface (i.e., particles of various sizes and films) exposed to these environmental conditions.
