dc.description.abstractWhen the synthesis of hydrogels, which are a hydrophilic group of polymers, occurs below the freezing point of water, the hydrogels gain a perfect property: porosity. Hydrogels with this property and resulting sponge-like structure are called cryogels (CRYs). The porosity of cryogels is affected by the amount of crosslinker used. In this study, how the amount of crosslinker affected the porosity initially was investigated, along with thermal, swelling, and crystallinity properties of polyacrylamide (PAAM) cryogels. Additionally, a series of composites (COMs) were synthesized with polyaniline (PAN) in the pore spaces of CRYs and again the effect of varying pore size on the electrical conductivity of COMs was researched. In the cryogel series, as the amount of N,N '-methylenbisacrylamide (MBA) increased, the pore size increased. The S, P, P-s, and V-p parameters increased in general with the MBA increase. The conductivity values of composites were determined in the interval of 1.6 x 10(-3)-4.5 x 10(-3) S cm(-1).
