Interaction forces between pre-adsorbed layers of branched poly(ethylene imine) (PEI) of different molecular mass were studied with the colloidal probe technique, which is based on atomic force microscopy (AFM). During approach, the long-ranged forces betw ...
Epoxy-functionalised hyperbranched polymers (HBP) were combined with aminosilanes to form coatings and their effect on the practical adhesion between galvanised steel and polyethylene was investigated. It was shown that HBPs were initially soluble in silan ...
Unlike traditional pressure sensitive adhesives, the natural setal arrays of gecko lizards achieve dry adhesion with stiff, keratinous material. This remarkable property has inspired a new class of adhesive and high friction microstructures composed of sti ...
Interface delamination during indentation of micron-scale ceramic coatings on metal substrates is modeled using discrete dislocation (DD) plasticity to elucidate the relationships between delamination, substrate plasticity, interface adhesion, elastic mism ...
Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...
In this project, we intend to use inkjet-based delivery of functional liquid droplets on pre-structured surfaces for the directed (self-)assembly of micro/nano-objects as experimental platform to build up and validate multi-level models of micro-droplet de ...
Self-assembled monolayer (SAM) films have attracted immense attention for both fundamental and applied research. A SAM is composed of a large number of molecules with a head group that chemisorbs onto a substrate, a tail group that interacts with the outer ...
Crawling cell motility is characteristic of most animal cells and is involved in many important biological processes such as embryogenesis, immune response, and wound healing. It involves several steps: protrusion (dynamic surface extension) at the front o ...
In recent years, superhydrophobic surfaces have attracted a considerable amount of attention from the academic and industrial communities. This growing interest is mainly caused by the fundamental physico-chemical theoretical aspects that remain obscure an ...
Abstract—The practical adhesion of maleic anhydride grafted polyethylene (MAH-PE) to galvanised steel was studied using 3-point flexure tests, before and after hydrothermal ageing. Before bonding, the electro-galvanised steel was treated with γ -aminopropy ...
