“…The AC power for sputtering was supplied by RF power generation (13.56 MHz). Samples were prepared following reported procedures [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. NaCl powder (particle size: 250 -500 μm, Kanto Chemical or The Salt Industry Center of Japan) was introduced into a hexagonal barrel and then the barrel was placed in a vacuum chamber.…”

“…Based on this background, we developed a novel surface modification method for powders using the sputtering technique, which we call the "polygonal barrel-sputtering method" [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. The polygonal barrel-sputtering method has been successfully used for uniform surface modification of particles composed of metals [17], alloys [18], metal oxides [19][20][21][22][23][24], polymers [25][26][27], and carbon [28][29][30][31][32]. In this study, the surfaces of NaCl particles were modified with metal films using the polygonal barrel-sputtering method to demonstrate the application of our method to the surface modification of water-soluble and water-reactive powders.…”

In this study, the surfaces of NaCl particles were modified with metal films using the polygonal barrel-sputtering method. When Pt was sputtered on NaCl particles, the individual particles changed from white to metallic. Characterization of the treated samples indicated that thin Pt metal films were uniformly deposited on the NaCl particles. Immersion of the treated NaCl particles in water revealed that they floated to the surface of the water with the increase in the immersion time, although their original cubic shapes remained unchanged. The floating phenomenon of the Pt-coated NaCl particles, as mentioned above, suggests that NaCl was dissolved by the permeation of water through invisible defects such as grain boundaries in the Pt films, leading to the formation of hollow particle-like materials. It should be noted that uniform film deposition on the NaCl particles could also be achieved by sputtering with Au or Cu. Based on the obtained results, our sputtering method allows uniform surface modification of water-soluble and water-reactive powders that cannot be treated by conventional wet process using water.

We have adopted the dip-pulling method and a thinning technique to obtain interpenetrating polymer network (IPN) thin films with suitable thickness and adhesive strength on Al substrates. X-ray photoelectron spectroscopy (XPS) and attenuated total reflection infrared spectroscopy (ATR-FTIR) were used to study the interfacial reactions, metal transformations, and nonmetal bond types between IPN and Al. By probing the binding energy shifts of nitrogen, aluminum, and oxygen atom species at different IPN/Al interfacial layers, the reactions between the polyurethane in IPN and the OH group in aluminum substrate could be determined. Moreover, the additional structures formed by the double bond between the nitrogen and nitrogen in the -NCO group in IPN suggested the existence of covalent bonding in the adhesion areas. Sufficient interfacial reactions occurring between IPN and Al effectively restricted the IPN peel off from Al substrate.

“…Different polymers such as Capton, Mylar, polypropylene, and polyethylene were ion implanted,8 and polyethylene and polycarbonate were coated with Al 9, 10. Au, Ag, Pd, Cu, and Ni were coated on poly(methylmetacrylate) (PMMA) particles by barrel sputtering,11 and cystalline metallic films were formed on the polymer surface. Ultrathin Al films were deposited on polyethylene terephtalate (PET) by electron ion beam deposition and coatings had grain size in the range of 19.8 and 35.7 nm.…”

In this study, the polypropylene-zeolite composite films having 2-6 wt % natural zeolite were coated with a thin film of aluminum (Al) by magnetron sputtering, and the contribution of the Al coating on film properties was investigated. The samples were characterized by EDX, X-ray diffraction, SEM, AFM, UV-visible spectroscopy, and water vapor permeation analyses. The surface of the films coated with a smooth Al film having 98-131 nm thickness. EDX revealed that Al percentage on the surface appeared to be as 8-10 wt % indicating contribution of polymer surface under Al film to analysis. XRD analysis showed that the grain size of Al at the surface was 22-29 nm. The surface roughness increased after Al-coating process. The transmission of coated films was very low for both UV and visible regions of the light spectrum. Permeation analysis indicated that water vapor permeation was lower for Alcoated material.
