“…Contact angle () measurement is one of the important indicators for wettability: the lower the contact angle the more wettable (hydrophilic) the surface is. However, it ought to be clarified that on a rough surface, the contact angle measurement is affected by the surface roughness even when the surface chemical composition is identical for a smooth and a rough surface [53]. When the surface is roughened, the apparent contact angle ( app ) can be altered by a geometric factor, given by Wenzel's equation [54]:…”

The formation of SiO 2 nanoparticles with uniform particle size is accomplished through direct hydrolysis of tetraethyl orthosilicate (TEOS), while the deposition of the formed SiO 2 on PP separators was conducted in the same solution containing polyvinylidene fluoridehexafluoropropylene (PVDF-HFP) as binders and acetone as the solvent. The effects of the ceramic coating on the surface morphology, tensile strength, contact angles, electrolyte uptake, thermal shrinkage of the PP separators and the cell performances such as battery rate capability and Coulombic efficiency were investigated. The coated separators show significant reduction in thermal shrinkage and improvement in tensile strength, contact angles, electrolyte uptake and battery performance as compared to the plain PP separator.

“…Also, Minjer et al used nitric acid treatment of soda lime glass following immersion in sulfuric and chromic acids to remove sodium ions and other impurities [25]. On polymer substrates as opposed to glass, solutions of chromic and sulfuric acids and potassium permanganate are commonly used [40][41][42]. Less harsh surface conditioning was used in a facile "dip and rinse" pretreatment method for hydrophobic polymer substrates prior to nickel (Ni) EL plating in a recent report by Wang et al [43].…”

“…Surface conditioning provides the substrate with cavities and, in some cases, a modified chemistry, which improves the wettability of the surface and sometimes renders a hydrophobic surface hydrophilic. The optimum conditioning time depends on the initial surface properties, which, in turn, are dependent on the composition and fabrication conditions used in production [17]. For the case of ABS plastics, the usual etching solutions are composed of chromic acid in aqueous sulfuric acid.…”

“…These all lead to the increased conductivity of plastic surface. Luan B. et al [17] studied the chemical surface preparation for electroless plating of stereo lithography polymers. They conducted the contact angle analysis to assess the surface hydrophilicity, so as to optimize the preparation process.…”

Metallization of ABS (acrylonitrile-butadiene-styrene) parts has been studied on flat part surfaces. These parts are fabricated on an FDM (fused deposition modeling machine) using the layer-wise deposition principle using ABS as a part material. Electroless copper deposition on ABS parts was performed using two different surface preparation processes, namely ABS parts prepared using chromic acid for etching and ABS parts prepared using a solution mixture of sulphuric acid and hydrogen peroxide (H 2 SO 4 /H 2 O 2 ) for etching. After surface preparations using these routes, copper (Cu) is deposited electrolessly using four different acidic baths. The acidic baths used are 5 wt% CuSO 4 (copper sulfate) with 15 wt% of individual acids, namely HF (hydrofluoric acid), H 2 SO 4 (sulphuric acid), H 3 PO 4 (phosphoric acid) and CH 3 COOH (acetic acid). Cu deposition under different acidic baths used for both the routes is presented and compared based on their electrical performance, scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDS). The result shows that chromic acid etched samples show better electrical performance and Cu deposition in comparison to samples etched via H 2 SO 4 /H 2 O 2 .
