Due to the establishment of common thermoplastics such as polyethylene, polypropylene and polytetrafluoroethylene as substrates for modern electrets, research in this field has seen significant progress in recent decades. However, there still is a need for new substrate materials in order to boost modern-day electret applications. Important targets for a further development are electret substrates...
Substituted benzene-1,3,5-tricarboxylic acid trisamides are known to be efficient nucleating agents and in some selected cases are clarifiers for isotactic polypropylene (i-PP). In this paper we expanded the application range of this class of additives to the area of i-PP electret materials. This paper discusses in particular the relation between charge storage properties and additive concentration...
A new class of triphenylamine-based trisamide compounds has been synthesized and their structure systematically varied in order to explore its influence on the nucleation efficiency for, and on the charge-storage properties of isotactic polypropylene (i-PP). The nucleation behavior was investigated by thermal analysis, polarized light microscopy and rheology in the concentration range from 0.01 to...
