Abstract :

As special types of hydrogels that are known as cryogels are super porous network of hydrophilic polymer chains and are prepared at cryogenic conditions (below the freezing point of solvent). Here, we report the preparation of polyethyleneimine (PEI) cryogel, and its use as a template for conductive polymers (CPs) synthesis. The synthesis of CPs such as p(Aniline) (p(An)), p(Pyrolle) (p(Py)) and p(Thiophene) (p(Th)) were accomplished by loading PEI cryogels with the corresponding monomers and then employing oxidative polymerization technique. The synthesized PEI/CPs cryogel composites denoted as PEI/P(An), PEI/P(Py) and PEI/P(Th) as semi interpenetrating network (IPN) were characterized spectroscopically by using FT-IR, thermally by means of TGA, and morphologically via SEM imaging. Various parameters such as the types and the effects of number of loading monomers into PEI cryogel networks, polymerization time and doping agents on conductivities of PEI/CPs semi-IPN composites were investigated. Furthermore, various applications of PEI/CPs semi-IPN composites for sensor and environment were also investigated.
