Influence of irganox 1010 on space charge behavior in thermal-oxidatively aged PP/elastomer blends
Polypropylene (PP) has been considered as a promising insulation candidate for high voltage direct current (HVDC) cables for its overall low cost and recyclable. To address its high stiffness in real application, a propylene-based elastomer (PBE), DOW VERSIFYTM 2200 was introduced while the potential lifetime of blends was confirmed to be reduced dramatically, only one quarter of that of pure PP. Based on this observation and the antioxidant (AO) can improve thermal stability, an AO has been introduced to investigate its influence in PP/elastomer blends thermal-oxidative ageing in this work. According to chemical changes characterized by Fourier-Transform Infrared (FTIR) spectroscopy, the AO react with oxygen initially on sample surface and is assumed to be consumed up between 3 and 4 weeks at 150 ℃ in a fan oven. The space charge accumulation behaviour was estimated by the pulsed electro-acoustic (PEA) method, where a resultant charge peak can be observed because of the positive charge movement brought by the AO content and negative charge accumulation near the cathode as a function of the poling time. It has been found that DC breakdown strength (BDS) shows an increase with ageing times till 4 weeks.

Abstract
Polypropylene (PP) has been considered as a promising insulation candidate for high voltage direct current (HVDC) cables for its overall low cost and recyclable. To address its high stiffness in real application, a propylene-based elastomer (PBE), DOW VERSIFYTM 2200 was introduced while the potential lifetime of blends was confirmed to be reduced dramatically, only one quarter of that of pure PP. Based on this observation and the antioxidant (AO) can improve thermal stability, an AO has been introduced to investigate its influence in PP/elastomer blends thermal-oxidative ageing in this work. According to chemical changes characterized by Fourier-Transform Infrared (FTIR) spectroscopy, the AO react with oxygen initially on sample surface and is assumed to be consumed up between 3 and 4 weeks at 150 ℃ in a fan oven. The space charge accumulation behaviour was estimated by the pulsed electro-acoustic (PEA) method, where a resultant charge peak can be observed because of the positive charge movement brought by the AO content and negative charge accumulation near the cathode as a function of the poling time. It has been found that DC breakdown strength (BDS) shows an increase with ageing times till 4 weeks.
