To produce the novel coatings, C-TiO2 was mixed with a ductile material, the polymer ECTFE, by means of a low energy ball milling (LEBM) process. The LEBM system permits the mechanical anchoring of small TiO2 aggregates around the large ductile polymeric particles. A well-bonded coating with good mechanical coupling was formed between the ball-milled mixture and the substrate. Photocatalytic tests showed that the LP-CGS nano-TiO2 coatings actively photodegraded NO and the by-product, NO2. Compared to commercial paint, the as-prepared coatings presented here enhanced photocatalytic performance. | URI: | http://hdl.handle.net/10553/43227 | ISSN: | 0169-4332 | DOI: | 10.1016/j.apsusc.2015.11.207 | Fuente: | Applied Surface Science [ISSN 0169-4332], v. 362, p. 274-280 |
