Special Issue Information

Dear Colleagues,

Multifunctional nanocomposite materials can be fabricated by combining a range of nanoscale reinforcement materials with a polymer matrix. With proper consideration of the performance requirements of a given application, it is possible to design a composite with a range of functionality necessary for successful operation. Traditional fillers are added to polymers to reduce costs, improve processing behavior, or modify the properties of the final product. Nanofillers might be the answer to the requirements of modern polymer materials. In comparison to traditional fillers, at much lower loading they can significantly improve or adjust the different properties of the polymer matrix into which they are incorporated (e.g., electrical, mechanical, thermal, optical, fire-retardant), sometimes in synergy with conventional fillers.

Carbon nanostructures such as fullerenes, carbon nanotubes, carbon nanofibers, and graphene derivatives have attracted a great deal of attention in the last three decades. Their outstanding mechanical, electrical, thermal, and optical properties, as well as their large aspect ratios and higher specific surface area make them very attractive as ideal nanofillers, which can contribute to the development of composites with improved mechanical and special properties (e.g., electrical conductivity, thermal conductivity, magnetic permeability, barrier properties). The synergistic effect of nanofiller hybrids including graphene nanoplatelets and carbon nanotubes, metal or metal-oxide nanoparticles anchored on a graphene surface in a hybrid can be also applied to obtain functional polymer nanocomposites.

This Special Issue aims to attract high-quality research and/or review articles that will help us to further understand the properties of polymer-based multifunctional nanocomposites containing carbon nanostructures or their hybrids.

The paper presents a method of obtaining composite cellulose fibres (CEL) doped with graphene oxide (GO) and the influence of GO nanoparticles on the structure and properties of the obtained fibres. Composite fibres (GO/CEL) were prepared using wet method from 5% CEL solutions in 1-ethyl-3-methylimidazolium acetate (EMIMAc) containing GO (0; 0.21; 0.50; 0.98; 1.97% w/w) dispersion in N,N-dimethylformamide (DMF). The fibres were coagulated in distilled water and methanol. Optical microscopy allowed us to demonstrate a good degree of GO additive dispersion in the CEL matrix. Surface morphology was examined by scanning electron microscopy (SEM) and infrared spectroscopy (FTIR), which indicated interactions between the matrix and the additive. Strength tests have shown that GO/CEL fibres are characterised by high values of elongation at break (7.7–19.5%) and tenacity (~133–287 [MPa]). The obtained composite fibres are characterized by good biocidal properties against Gram-negative bacteria (Escherichia coli), Gram-positive bacteria (Staphilococcus aureus), and fungi Candida albicans, and the resistance to microorganisms depends on the surface zeta potential value and the isoelectric point (IEP) of GO/CEL fibres.

In this work, hybrid filler systems consisting of multi-walled carbon nanotubes (MWCNTs) and nano carbon black (nCB) were incorporated by melt mixing in low-density polyethylene (LDPE). To hybrid systems a mixture of MWCNTs and nCB a mass ratio of 1:1 and 3:1 were used. The purpose was to study if the synergistic effects can be achieved on tensile strength and electrical and thermal conductivity. The dispersion state of carbon nanofillers in the LDPE matrix has been evaluated with scanning electron microscopy. The melting and crystallization behavior of all nanocomposites was not significantly influenced by the nanofillers. It was found that the embedding of both types of carbon nanofillers into the LDPE matrix caused an increase in the value of Young’s modulus. The results of electrical and thermal conductivity were compared to LDPE nanocomposites containing only nCB or only MWCNTs presented in earlier work LDPE/MWCNTs. It was no synergistic effects of nCB in multi-walled CNTs and nCB hybrid nanocomposites regarding mechanical properties, electrical and thermal conductivity, and MWCNTs dispersion. Since LDPE/MWCNTs nanocomposites exhibit higher electrical conductivity than LDPE/MWCNTs + nCB or LDPE/nCB nanocomposites at the same nanofiller loading (wt.%), it confirms our earlier study that MWCNTs are a more efficient conductive nanofiller. The presence of MWCNTs and their concentration in hybrid nanocomposites was mainly responsible for the improvement of their thermal conductivity. Full article
