“…11 An aqueous room-temperature solution (40 mL) of CuSO 4 AE5H 2 O (0.054 M) acted as a source of copper(II) ions, stabilized by chelation with EDTA (0.034 M). Coupons (20 mm 2 ) of pristine (unfunctionalized) alumina-coated silicon wafer (A) and isonicotinic acid-functionalized alumina wafer (iNA-A) were added to the solution prior to the addition of hydrazine hydrate solution (1.3 mL), which triggers the electroless deposition process.…”

“…[7][8][9] The reason for this selective deposition is that the functionality of the SAM acts as an accelerator molecule to control crystal heterogeneous nucleation and growth. Amino groups, catechols, and thiols have all been used to seed metallic ELD copper growth on surfaces, [10][11][12] and they can also be used to assist in electrochemical deposition. 13 Pyridine and related derivatives represent one of the most common ligand types for copper, [14][15][16][17] and we have used this in our work with copper-specific complexes.…”

Isonicotinate self-assembled monolayers (SAM) were prepared on alumina surfaces (A) using isonicotinic acid (iNA). These functionalized layers (iNA-A) were used for the seeded growth of copper films (Cu-iNA-A) by hydrazine hydrate-initiated electroless deposition. The films were characterized by scanning electron microscopy (SEM), electron-dispersive X-ray spectroscopy, atomic force microscopy, Xray photoelectron spectroscopy, X-ray diffraction, and advancing contact angle measurements. The films are Cu 0 but with surface oxidation, and show a faceted morphology, which is more textured (R q = 460 ± 90 nm) compared to the SAM (R q = 2.8 ± 0.5 nm). In contrast, growth of copper films by SnCl 2 /PdCl 2 catalyzed electroless deposition, using formaldehyde (CH 2 O) as the reducing agent, shows a nodular morphology on top of a relatively smooth surface. No copper films are observed in the absence of the isonicotinate SAM. The binding of Cu 2+ to the iNA is proposed to facilitate reduction to Cu 0 and create the seed for subsequent growth. The films show good adhesion to the functionalized surface.

“…Before the metal plating step, the polyester fibers were functionalized by polydopamine. 11 The polydopamine functionalized polyester fibers were sensitized and activated in a SnCl 2 and a PdCl 2 solution, respectively. Fe and Co were deposited on the surface of fibers in the plating solution which is composed of FeSO 4 ·7H 2 O, CoSO 4 ·7H 2 O, NaBH 4 , and NaOH.…”

A novel Fe-Co binary hollow fiber was synthesized by electroless plating using hydrolyzed polyester fiber and its anisotropy characteristic was investigated for electromagnetic wave absorbing materials. The hollow fibers in parallel with magnetic field show higher saturated magnetization of 202 emu/g at the applied magnetic field of 10 kOe and lower coercivity (27.658 Oe), compared with the random and vertical oriented hollow fibers. From complex permittivity measurement, the Fe-Co hollow fiber composites clearly display a single dielectric resonance, located at ∼14 GHz. The Fe-Co hollow fibers not only provide excellent EM properties in GHz frequency ranges, resulting mainly from the strong resonance, but also adjust the soft magnetic properties through fiber alignments. The cavitary structure of the Fe-Co hollow fibers, not only giving rise to a dielectric loss resonance and also adjusting its peak frequency, may be a pathway to useful EM wave absorptive devices in GHz frequency ranges.

“…But such method involves the use of undesirable Sn (II). Mondin et al [25] developed a simple process only using polydopamine activator for selective electroless metal deposition. Glickman et al introduced an ordered monolayer of mercapto-and amino-silanes that were used as coupling agents between silica ubstrate and nanosized gold catalysts [26].…”
