Templating the patterning of gold nanoparticles using a stained triblock copolymer film surface

The selective staining of the polyisoprene block in a polystyrene–polyisoprene–polystyrene triblock copolymer enables nanoparticles of sputtered gold to be patterned into stripes, templated by the stained block copolymer lamellae.

Novel multi end-functionalised polymers. Additives to modify polymer properties at surfaces and interfaces

Fréchet-type poly(arylether) dendrons with up to eight trifluoromethyl peripheral groups have been used as initiators in the copper mediated living radical polymerisation of d-styrene, the surface adsorption behaviour and resulting properties of these polymers in blends have been investigated by ion beam analysis and contact angle measurements.
