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 3

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

% HNT	% in UV region (350 nm)	% in visible region (550 nm)
0	38.28	64.72
1	32.66	58.63
2	19.56	45.10
