Preparation of Size Controllable Polypyrrole Sub‐Microcapsules Using SEBS Copolymer as the Building Block

Abstract

Summary: SEBS is used as building blocks to fabricate size controllable polypyrrole (PPy) capsules. Polypyrrole shells grow on the surfaces of the size controllable oxidant sub‐microparticles dispersed in the solution cast film of a SEBS copolymer by vapor phase polymerization. After washing in ethanol, PPy sub‐microcapsules dispersed in a SEBS matrix are obtained. This technique shows advantages of lower cost and less pollution, as compared with the gold‐template method reported in the literature.

Effects of carbon blacks with various structures on vulcanization and reinforcement of filled ethylene-propylene-diene rubber

“…The resistivity of EPDM filled with N472 was measured by a conventional four-point probe technique in which the electrodes were separated by 1 mm as reported [24]. The four probes were slightly pressed on the EPDM samples to ensure a good contact.…”

Toluene-Filled Polypyrrole Microvessels: Entrapment and Dynamics of Encapsulated Perylene

“…Conjugated polymer hollow structures can change their permeability or optical properties by changing the protonation or oxidation state of the polymer, thereby providing facile control over processes such as release and uptake of encapsulated species, light emission, or conductivity, for example. Spherical or cap-like structures have been prepared through template synthesis using solid, – liquid, – and gaseous – templates.…”
