Fundamental investigations on the barrier effect of polyester micro fiber fabrics towards particle-loaded liquids induced by surface hydrophobization
As the title implies, the chief goal of the present work is the improvement of the barrier effects of textile fabrics in the medical sector, in particular, in the operating room, which would be an effective safeguard against the causative pathogens allowing the health workers to work in and around …

Hydrophobization of Cellulose-Based Fibers for Packaging Applications with Alkyl Ketene Dimers (AKD) and Food-Grade Waxes via Supercritical Impregnation with Carbon Dioxide – Experimental and Thermodynamic Modeling Approaches
This modified material has applications in food packaging, where frequently water-repellant surfaces are required. This method is preferable to traditional coating methods because it sizes across the entire thickness of the substrate rather than just the surface and can be used for non-planar …

TEMPO-oxidized Nanocelluloses: Surface Modification and use as Additives in Cellulosic Nanocomposites
… were compared as treatment techniques for the hydrophobization of TONc surfaces with octadecylamine (ODA). Subsequently, TONc and its covalently coupled derivative were evaluated as nanofiber reinforcements in a cellulose acetate butyrate (CAB) matrix. The properties of the resulting …

Lubrication Forces in Polydimethylsiloxane (PDMS) Melts
… presence of the water layer was controlled by hydrophobization of the solid. In the second part, the possibility of forming a lubrication layer during shear was examined. Three polymer melts were compared: octamethyltrisiloxane (OMTS, n = 3), PDMS (n <sub>avg</sub> = 322), and a mixture of 70 …

Metallization Process for 3D Printed Electronics: from i3DP II to 3D Co-printing Technology
… water treatment, surface hydrophilization and hydrophobization are demonstrated. Beside materials development, a dual-light 3D printing technology is developed as a 3D co-printing method, which is employed to fabricate 3D printed electronics with a customized 3D printing resin integrated with …

Scale-up of Using Novel Dewatering Aids
… before adding the dewatering aids. This two-step hydrophobization process was able to reduce the cake moisture and also increase the throughput.

Design, Processing, and Characterization of Nanocomposites
… fibers were altered through surface hydrophobization and salt saturation to influence ignition propagation rate and ignition nucleating points. Samples were ignited at both slow and rapid rates, with flash burning of these nanofibers producing graphene oxide nanotubes through ignition …

Modification of nanoparticle surfaces for emulsion stabilization and encapsulation of active molecules for anti-corrosive coatings
… this work, three physicochemical methods for the hydrophobization of initially hydrophilic solid particles are investigated. The modified particles are then used for the stabilization of oil-in-water (o/w) emulsions. For all introduced methods electrostatic interactions between strongly or weakly …

GREEN CATALYTIC STRATEGIES FOR THE PRODUCTION OF BIOBASED BUILDING-BLOCKS
… of the support and the post-metal deposition hydrophobization through silane grafting. In the first case, two different SiO2 materials, namely one less hydrophilic pyrogenic and one hydrophilic gel, were chosen to prepare two copper catalysts CuO/SiO2 A and CuO/SiO2 B respectively. The …
