Determination of Hansen Parameters of Nanoparticles: A Comparison of Two Methods Using Titania, Carbon Black, and Silicon/Carbon Composite Materials

Abstract

AbstractHansen solubility parameters (HSPs), for particles understood as Hansen similarity parameters, can provide valuable information about the surface behavior of nanoparticles. In the past years, several methodologies are developed for scoring and ranking of probe liquids for HSP determination. Two methods available to carry out this determination in a structured way are based on integral extinctions (IE) by Süß et al. and particle size determinations by Anwar et al., respectively. In this study, these two methods of HSP determination are applied on titania, carbon black, and silicon/carbon composites. The differences in scoring and subsequent ranking of a probe liquid list are compared between both methods. Comparable HSPs from both methods are reported as a best‐practice example and additional considerations that need to be considered to properly derive HSPs from the IE‐based method are emphasized.
