Abstract

The dynamics of the two components of self-assembled diblock polyisoprene (PI)-polydimethylsiloxane (PDMS) copolymers is investigated by means of broadband dielectric spectroscopy. By varying the size of the PDMS blocks, different PI segregation geometries are obtained, namely lamellas, cylinders, and spheres, with typical sizes in the range 6–16 nm. In this way, we identify the effects of the nanostructure on the dielectric relaxation of the polymer components: the α-relaxation of PI and PDMS blocks as well as the normal mode of PI blocks. Two different situations are explored: (1) the PDMS dynamics is detected in a temperature range where the PI phase is frozen and (2) the PI dynamics is detected in a temperature range where the PDMS phase is highly mobile. Thus, using a single system, the similarities and differences between hard and soft confinement are investigated.

Rheological measurements were performed in an ARES rotational rheometer, TA Instruments, using an oscillation frequency of 1 Hz, strain amplitude of 2 % and temperature sweep at 3 K/min. The measuring geometry was plate/plate with a diameter of 25 mm and a sample thickness of 1 mm. Nitrogen atmosphere was used during the whole experiments
