Halloysite Nanotubes Noncovalently Functionalised with SDS Anionic Surfactant and PS-b-P4VP Block Copolymer for Their Effective Dispersion in Polystyrene as UV-Blocking Nanocomposite Films

Table 4

Variation of % in case of pure PS film and the nanocomposite films containing BCP modified HNTs with the amount of HNTs (no variations in the optical properties for BCP/PS films have been found compared to neat PS).

% HNT	% in UV region (350 nm)	% in visible region (550 nm)
0	38.27	64.71
1	13.18	36.05
2	10.82	24.78
5	8.40	20.01
