Properties of polymers in blends can be enhanced if molecular control is achieved. In this paper, we spread nitrile rubber (NBR) and polyfluorene (PF) on the air–water interface to form stable monolayers, as observed with surface pressure–area is

This paper proposes to obtain homogeneous and stable blends of oligo(9,9-dioctylfluorene)-co-phenylene (OF), a conjugated oligomer with strong tendency of formation of excimers in the solid state, and nitrile rubber (NBR). This rubber protection redu
