Scenarios for simulations with varying parameters. Model parameters of each scenario are the same as for simulating charge transport in LDPE, except for those provided in the right column. Charge mobilities (in m²·V⁻¹·s⁻¹) are listed in order of increasing temperature (RT; 40 °C; 60 °C).

Scenario	Description	Model parameters	Modified parameters
#1	Reduction of charge injection at electrodes	Charge injection barrier heights as for the nanocomposite, all other parameters as for LDPE	φK = 1.31 eV φA = 1.26 eV
#2	Reduction of charges released from deep traps	De-trapping barrier heights as for the nanocomposite, all other parameters as for LDPE	φetr = 1.00 eV φhtr = 1.00 eV
#3	Reduction of charge carrier mobility	Mobility of electrons and holes as for the nanocomposite, all other parameters as for LDPE	µe = 1 × 10−14; 3 × 10−14; 7 × 10−14 µh = 2 × 10−15; 6 × 10−15; 1.4 × 10−14
#4	Increase of trap densities	Trap densities as for the nanocomposite, all other parameters as for LDPE	Netr = 6.25 × 1021 m−3 Nhtr = 6.25 × 1021 m−3
