(a) Comparison of particle sizes of amorphous CRV starting material before and after hot melt coating and resulting coating mass ratios. Amorphous CRV particles were coated with 10% (w/w) PS65 and 20% (w/w) PS65, respectively. Results are presented as mean ± SD (n = 3). Representative SEM images of an uncoated amorphous CRV particle (b), a CRV particle coated with 10% (w/w) PS65 (c), and a CRV particle coated with 10% (w/w) PS65 as a cross-section including a representative determination of the coating layer thickness in (d).
