Photocatalytic activity and UV- protection of TiO2 nanocoatings on polylactic a...
Carneiro, Joaquim A. O.; Teixeira, Vasco M. P.; Nascimento, José Heriberto Oliveira do; Neves, J.; Tavares, P. B.The application of nanocoatings in the textile finishing is increasingly being explored because they open a whole new vista of value-addition possibilities in the textile sector. In the present work, low temperature pulsed DC magnetron sputtering method was used to create functional TiO2 nanocoatings on poly(lactic acid) textile fibres surfaces. In this study, the principal objectives in the application of TiO2...
Spectroscopic and structural studies of di-ureasils doped with lithium perchlorate
Nunes, Sílvia; Zea Bermudez, V. de; Ostrovskii, David; Tavares, P. B.; Barbosa, P. C.; Silva, Maria Manuela; Smith, Michael JohnDi-urea cross-linked POE/siloxane hybrid ormolytes (di-ureasils) doped with a wide concentration range of lithium perchlorate trihydrate (LiClO4·3H2O) (200 ≥ n ≥ 0.5, where n expresses the salt content in terms of the number of ether oxygen atoms per Li+ ion) have been analysed by Fourier transform infrared and Raman (FT-IR and FT-Raman, respectively) spectroscopies and X-ray diffraction (XRD). The results obta...
