PHB is a biodegradable polymer based on renewable raw materials that could replace synthetic polymers in many applications. A big advantage the resulting reduction of waste problem, as well conservation fossil resources. To arrange it for various applications, surface arranged by plasma-enhanced chemical vapor deposition (PECVD) with amorphous hydrogenated carbon layers (a-C:H). Here, 50 µm thick PHB-foil, a-C:H different thicknesses (0–500 nm) were deposited nm steps. Surface topography was...
The increasing use of polymers is related to a growing disposal problem. Switching biodegradable such as polybutylene adipate terephthalate (PBAT) feasible possibility, but after industrial production commercially available material PBAT not suitable for every application. Therefore, surface refinements with amorphous hydrogenated carbon films (a-C:H) produced by plasma-assisted chemical vapor deposition (PE-CVD) changing the top layer characteristics are used. Here, 50 µm-thick coated a-C:H...
Polyamide 6 (PA6) is a commonly used material in many different sectors of modern industry. Herein, PA6 samples were coated with amorphous carbon layers (a-C:H) increasing thickness up to 2 µm using radio frequency plasma enhanced chemical vapor deposition for surface adjustment. The morphology the coatings was inspected by ex situ atomic force microscopy and scanning electron microscopy. Surface wettability checked contact angle measurements. composition analyzed sensitive synchrotron...
Polyhydroxybutyrate (PHB) is a bio-based, biodegradable and commercially used polymer, which in its native form unfortunately not generally applicable. A widely technique to adapt polymers wider range of applications the surface modification with amorphous hydrogenated carbon (a-C:H) layers, realized by plasma-enhanced chemical vapor deposition (PE-CVD). However, this process creates intrinsic stress layer–polymer system can even lead full layer failure. The aim study was investigate how...
A preplated frame (PPF) consisting of Au/Pd/Cu-Sn/Cu substrate, i.e., with a Cu-Sn alloy instead Ni commercially used, was fabricated by electroplating and then the feasibility as an alternative PPF investigated. The wettability better than that Ni, resulting in excellent contact substrate smoother surface on upper Au/Pd protective layer. By XPS analyses, it confirmed Cu atoms layer did not diffuse through thin to at temperatures used IC assembly. wire pull-strength solderability were almost...
