In this article, new conductive hybrid biopolymer nanocomposites based on polylactid and humic substances were developed and studied. It has been established that humic substances, which were obtained from brown coals by extraction method, are characterized by nano dispersion in the range of 52–380 nm. It was found that due to the presence of a large number of active functional groups on the surface of such nanoparticles of humic substances is a hybrid modification of polylactid by the mechanism of template synthesis, which is accompanied by an increase in the degree of crystallization and the formation of a more rigid polymer structure, which allows to obtain hybrid biopolymer nanocomposites with significant impact strength and breaking stress during bending. It was also found that the obtained hybrid biopolymer nanocomposites based on polylactid and humic substances are characterized by levels at the value of resistance from 25 to 31 Ω sq −1 . It is concluded that the designed hybrid biopolymer nanocomposites based on polylactide and humic substances in terms of their strength properties and complex of spectral-electrical characteristics are a promising basis for obtaining polymer matrices and materials for micro- and nanoelectronics.
