                         emerged as an alternative to get Boron-Doped Diamond (BDD-CNTs) 
                         and Nitrogen-Doped Diamond (NDD-CNTs) porous films. This work got 
                         excellent wet individual seeding of each carbon nanotube of a CNT 
                         forest with minimum changes to its original morphology. The use of 
                         an oxygen plasma to graft polar groups on the CNT surface enabled 
                         efficient electrostatic self-assembling (ESA) of nanodiamonds from 
                         a dispersion in a KCl diluted solution. The use of other routes 
                         with polymer functionalization and/or polymer based nanodiamond 
                         dispersion always left some residues and promoted nanodiamond 
                         bridging among carbon nanotubes. Even though any of the 
                         alternatives may produce porous diamond-CNT composites, the one 
                         grown to reproduce closely CNT morphology may allow much better 
                         results, as a larger surface area. Thermal Chemical Vapor 
                         Deposition (CVD) via floating catalyst produced the CNTs. Two 
                         different procedures promoted functionalization, either by 
                         immersion in the cationic polymer PDDA (Poly 
                         Diallyldimethylammonium Chloride) or O2 plasma functionalization. 
                         Seeding went on from 4 nm diamond particles dispersed either in DI 
                         water with the anionic polymer Poly Sodium Styrenesulfonate (PSS), 
                         or with a KCl solution in DI water. A Hot Filament Chemical Vapor 
                         reactor deposited diamond film on the CNTs. The composites were 
                         characterized through Raman Spectroscopy, Scanning Electron 
                         Microscopy with a Field Emission Gun (FEG-SEM) and Energy 
                         Dispersive X-ray Spectroscopy (EDS).",
