چکیده
A method for the application of carbenes as reactive intermediates for surface modification of polymeric substrates has been developed; the efficacy of the process has been demonstrated by irreversible dyeing of polystyrene, polythene, nylon, silica, and controlled pore glass, and to a limited extent, polytetrafluoroethylene.

Versatile and efficient functionalisation of multiallylic dendronised polymers: can dense packing be reached?
Surface modification of a multiallylic dendronised polymer was performed using hydrosilylation, hydroboration or radical addition of thiols to cover the polymer with various functional moieties; surface congestion is expected to occur when bulky groups are grafted.
متن کاملDynamic nuclear polarisation NMR of nanosized zirconium phosphate polymer fillers.
Surface functionalisation with organic modifiers of multi-layered zirconium phosphate (ZrP) nanoparticles used as polymer fillers can be directly probed by dynamic nuclear polarisation NMR, which provides unambiguous evidence of the presence of P-O-C chemical bonds at the surface of the ZrP layers, thereby confirming successful functionalisation.

متن کاملImmobilisation of Cell-Binding Peptides on Poly--Caprolactone (PCL) Films: A Comparative XPS Study of Two Chemical Surface Functionalisation Methods
Successful interaction between cells and biomaterial surfaces is crucial for biomedical devices, and incorporation of peptides such as RGD (Arg-Gly-Asp) at the polymer interface can substantially promote cell adhesion and proliferation. X-ray photoelectron spectroscopy (XPS) has been used to characterise poly--caprolactone (PCL) films modified by aminolysis and the introduction of RGD peptides...
