W artykule przedstawiono badania pod względem struktury materiałów przeznaczonych na innowacyjne detektory gazowe. Materiały te bazują na nanorurkach węglowych (NW), nanokrystalitach Pd i nanokrystalitach Ni. Materiały te otrzymywane są w postaci warstw przygotowanych w wielokrotnych procesach PVD, CVD. Nasze badania elektrono-mikroskopowe, FTIR oraz rtg pokazały strukturę tych materiałów zarówno...
We present the optical properties of the nanocomposite nickel - carbonaceous (Ni-C) and carbon nanotubes, palladium-fullerene (CNT- Ni-Pd) films obtained by various methods. The initial film was prepared by physical vapor deposition (PVD) method using two separated sources: fullerene C 60 (as carbon source) and nickel acetate (as metal source). Next, the initial film was modified by chemical...
Nanorurki węglowe otrzymywano za pomocą dwuetapowej metody PVD/ CVD. W pierwszym etapie (proces PVD) wytworzono warstwę węglową zawierającą nanoziarna Ni. W drugim etapie (proces CVD) warstwa z Ni została zmodyfikowana w celu otrzymania nanorurek węglowych osadzonych w matrycy węglowej. Czas procesu CVD został tak dobrany, aby otrzymać nanorurki w różnych etapach wzrostu (10, 20, 30 min). Wytworzone...
Composite films of nano-size nickel grains embedded in a carbonaceous matrix are synthesized by a PVD process of C 60 fullerenes and Ni acetate. The morphology of the nano-composite films is characterized by TEM, selected area electron diffraction, chemical analysis and AFM. Correlations with deposition parameters and typical structure changes are found. The mechanical properties are analyzed...
