Chemisorbed poly(propylene sulphide)-based copolymers resist biomolecular interactions

Horst Vogel, Samuel Terrettaz, Jeffrey Alan Hubbell, Nicola Tirelli

Alkanethiolates have been widely used as chemisorbates to modify gold surfaces, in spite of their relatively poor oxidative stability. We introduce gold-chemisorbing block copolymers bearing an anchoring block of poly(propylene sulfide) (PPS), selected in ...

Acrylic acid grafting and collagen immobilization on poly(ethylene terephthalate) surfaces for adherence and growth of human bladder smooth muscle cells

Florian Maria Wurm, Peter Frey

In tissue engineering, degradable or non-degradable polymer matrices can act as cell-carrier-scaffolds. Cell adhesion and growth on these scaffolds can be promoted by immobilizing extracellular matrix proteins. Therefore, in this study, polymer poly(ethyle ...

Silicone elastomer stamp with hydrophilic surfaces and method of making same

Heiko Wolf, Bruno Michel, Emmanuel Delamarche, Christian Donzel

A method for fabricating silocone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydr ...

Time-temperature-transformation diagram for reactive processing of polyamide 12

Pierre-Etienne Bourban

In order to describe the different events occurring during the anionic polymerization of polyamide 12 (PA12), a general concept of a time, temperature, and transformation (TTT) diagram was established and related to reactive processing conditions. Polymeri ...

Effect of inclusions and blending on the mechanical performance of recycled multilayer PP/PET/SiOx Films

Yves Leterrier

Extending the useful life of materials through recycling has proven to be an efficient means of reducing natural resource use and limiting the production of waste. In the case of polymer-based materials, in general, and of packaging materials, in particula ...

Biomimetic Catalysis with Immobilised Organometallic Ruthenium(II) Complexes: Substrate and Regioselective Transfer Hydrogenation of Ketones

Kay Severin

Chloro-(h6-arene) complexes of Ru(II) with N-sulfonyl-1,2-ethylenediamine ligands that have one or two styrene side chains were synthesized and characterized. The chloro ligand was substituted with a diphenylphosphinato ligand and the resulting organometal ...

Tailored interfacial properties for immiscible polymers by hyperbranched polymers

The influence of hyperbranched polymer grafted polypropylene (PP-HBP) on the interfacial adhesion between fusion bonded bilayers of polypropylene (PP) and polyamide 6 (PA6) and on the properties of PP/PA6 blends was investigated. The interfacial adhesion b ...

Properties of thin anti-adhesive films used for the replication of microstructures in polymers

Giorgio Margaritondo

The aim of this work was to investigate the degradation of the anti-adhesive properties of protective PTFE films during the hot embossing of thermoplasts, and to identify possible failure causes which reduce the lifetime of these films. A comparative XPS s ...
