Sustainable chemistry requires application of green processes and often starting materials originate from renewable resources. Biomass-derived monomers based on five-membered γ-butyrolactone ring represent suitable candidates to replace sources of f

1,2,4,5-Tetrafluorobenzene has been utilized as suitable central acceptor moiety in push–pull chromophores having D-π-A-π-D quadrupolar arrangement. Starting from commercially available 1,4-diiodotetrafluorobenzene, nine novel chromophores with s

A first inter-laboratory comparison was conducted to demonstrate and document the capability of interested laboratories to measure the fraction of C-OH species on a plasma oxidised poly(propylene) sample by using a chemical derivatisation XPS approac

Thin composite layers (tin in plasma polymer matrix) were prepared in a stainless steel vacuum chamber. An RF powered magnetron with tin target was used to excite the discharge and to activate the monomer species ( n -hexane). The gas mixture introdu

The determination of functional groups on complex polymer surfaces by X-ray photoelectron spectroscopy (XPS) can be improved considerably by derivatization reactions. Simple polymers containing hydroxyl groups or amino groups were investigated as ref

TFAA has been used widely for the derivatization of hydroxyl groups in XPS of organic polymers. Unfortunately, in the presence of other nucleophilic groups at the surface like amino groups, these also react with TFAA and a quantification of the diffe

Over the last 40 years we have witnessed an impressive development of the tools for the analysis of polymer surfaces. However, there still are questions, which are very challenging and the quest of answering these questions means working at the front

A single-step process to polymer nanofiber meshes that possess biofunctional peptide segments on their surfaces is described here, which requires a standard electrospinning setup only. Spinning a homogeneous mixture composed of a valuable polymer-pep

A new technique for the production of nanoscale polymer networks on surfaces is presented. Bifunctional oligomeric building blocks react with trifunctional linkers and couple to activated polymer surfaces. PEG diamines were used as branch molecules i

A modular strategy toward (bio)functional nanofiber meshes by electrospinning is described. In contrast to commonly established, multistep protocols or complex spinning setups, a straightforward single-step procedure is investigated to obtain polymer
