Polyaniline base was protonated by blending with camphorsulfonic
and picric acids in the
solid state. The electrical conductivity of the equimolar mixture
was more than 107 times higher compared
with the conductivity of components used for blending. The
electrical conductivity still increased several
times after heating of mixtures to 85 °C. The protonation is
reflected by the changes in the infrared
spectra. The dependences of the electrical conductivity on the
composition of blends differ for the partly
protonated polyaniline and mixtures of protonated polyaniline with an
excess acid.
Проведена последовательная сорбция вируса B/Москва/04/2017 и бактерий, Staphylococcus aureus, Shigella flexneri 2a, на электро проводящие полимеры – полипиррол (PPy) и полианилин (PANI), а также их композиты с наночастицами серебра (PPy-Ag). Показано, что сорбционная активность полимеров, содержащих предварительно сорбированный вирус, в отношении бактерий снижается в следующей последовательности: PANI > PPy-Ag >PANI-Ag > PPy (для Shigella flexneri 2a) и PANI > PANI-Ag> PPy-Ag > PPy (для Staphylococcus aureus). Высокие сорбционные характеристики позволяют использовать данные материалы в качестве фильтров двойного назначения - антивирусных и антибактериальных
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
