“…The cross-linked asphaltenes with porous carbon nanosheet could allow more active sites and encourage ion/charge rapid transport and/or exchange . Hence, cross-linked asphaltenes with nanoporous networks might have applications as ad/absorber matrix, in membranes for CO 2 separation, as catalyst materials, and in supercapacitor electrodes as new energy-storage devices, and the nanoporous cross-linked asphaltenes could be new nano-objects for applications in electronics . We intend to continue our research efforts by “purifying” asphaltenes using pyrolysis, carbonization of asphaltenes at elevated temperatures, testing for new applications, and further detailed characterization of cross-linked and carbonized asphaltenes by different techniques such as microscopy and chromatography.…”

The complexity in the chemical structure of asphaltenes has the potential to be utilized in generating novel materials. In the present study, three different asphaltene samples derived from heavy and light crude oils are cross-linked in a chlorinated solvent. Diffuse reflectance infrared Fourier transform spectroscopy was used for the identification of functional groups and aliphatic-to-aromatic ratios type index values of cross-linked asphaltenes. Raman spectra of asphaltenes showed an increase in average molecular dimensions of cross-linked asphaltenes compared to the original asphaltenes without cross-linking. A porous network-type structure is proposed for explaining the structure of the cross-linked asphaltenes, and this is revealed by surface area analysis. It seems that it is possible to cross-link asphaltenes independent of their geographical origin. The experimental procedure here could be applied for similar materials as well. The cross-linked asphaltenes with porous network-type structure might act as a precursor material for making activated porous carbons, a carbonaceous scaffold for synthesizing novel materials in the confined state, and for modifying surfaces of nanomaterials.

In this work, composite materials based on LLDPE and asphaltenes, their functionalized derivatives, and an industrial residue of solvent deasphalting of tar were investigated. Physicomechanical, thermal and electret properties of composite materials were studied. The behavior of the compositions during melting and crystallization was studied by DSC, and crystallinity degree was calculated. The dispersion of oil fillers in a polymer matrix was investigated using SEM

“…По различным данным [1][2][3] высокомолекулярные соединения нефти -асфальтены, содержатся в нефтях и продуктах ее переработки в количестве до (0,1-80% масс.). Так, в нефтяных дисперсных системах асфальтены находятся в виде надмолекулярных структур размерами от 1 до 1000 нм, кроме того имеются данные о принадлежности асфальтенов к широкополосным аморфным полупроводникам [5][6][7][8][9]. В последние годы появились работы, в которых исследована молекулярная, электронная и надмолекулярная структура асфальтенов и кластеров на их основе [10][11][12][13][14].…”

Исследована надмолекулярная структура кластеров, образованных из молекулярных наночастиц асфальтенов, с применением расчетных и экспериментальных методов. Изучены образцы асфальтенов из термообработанного остатка вакуумной перегонки нефти. Проведены квантово-химические расчеты наночастиц методами молекулярной механики и самосогласованного поля. Изучены нанокластеры, построенные по данным эксперимента и включающие от 2 до 10 молекулярных фрагментов. Установленанепланарность структуры наночастиц асфальтенов. Методами атомно-силовой микроскопии проведено исследование топографии поверхности и расчет структурных параметров молекул асфальтенов. Результаты свидетельствуют о дискообразных надмолекулярных структурах, построенных из ассоциатов молекул асфальтенов.
