Establishing a relationship between the features of the synthesis and properties and specific interactions between components and the environment of new "smart" hybrid nanocomposites of conjugated biocompatible polymers and biopolymers and, based on this, developing approaches to controlling the target characteristics of such materials

popup.description2

New "smart" nanocomposites of poly(3,4-ethylenedioxythiophene) doped with sulfosalicylate anions (PEDOT), polypyrrole (PPy) doped with toluenesulfonate anions, and polydopamine (PDA) with polyvinylidene fluoride (PVDF) and polystyrene/poly-N-isopropylacrylamide (PS/PNIPAM) were synthesized. The features of the formation of these nanocomposites were established. The results of the research of the properties, structure and interfacial interactions of PVDF/PEDOT, PS/PNIPAM/PPy, PS/PNIPAM/PDA, halloysite nanotubes (HNT)/PPy, graphene/poly(3-methylthiophene) (P3MT), ZnO/P3MT nanocomposites indicate the possibility of their using as materials with adjustable properties for gas sensing (for example, ZnO/P3MT and HNT/PPy), drug delivery (PS/PNIPAM/PDA), removing toxic compounds from contaminated aqueous solutions (HNT/PPy), antistatic protection and electromagnetic shielding (graphene/P3MT). In particular, high sorption capacities of HNT/PPy nanocomposites for anionic (dyes) and oxidizing (potassium bichromate) adsorbates have been established. It has been shown that by adjusting the composition of nanocomposites, it is possible to govern the balance between intra-phase (hydrophilic-hydrophobic interactions in PNIPAM, an alteration of hydrophobic interaction between isopropyl groups) and interphase interactions (hydrogen bonding between amine and carbonyl groups of PNIPAM-PDA) and thus influence the properties of the PNIPAM phase (lower critical solution temperature).
