“…The analysis of the papers [13][14][15][16][17][18] shows that multi-functionality is achieved through introducing various additives in the formulation of the existing materials in form of coarse fractions or fine (nano-) particles. The introduction of nanoparticles in the matrix dramatically alters the structural characteristics of materials; as such, the necessary properties and functions of innovative materials can be accomplished by varying the amount of particles introduced [19][20][21][22]. In the work [23], the authors highlight that composite materials based on cement (C) and bitumen emulsion (BE) have been the most popular in recent years, including their extensive use in construction, and will remain the most promising option for some time to come.…”

The relevance of this paper is based on the increasingly larger volumes of reconstruction of buildings and structures and also with the opportunity to use polymer-bitumen binder based multifunctional materials for construction and installation purposes during such works as sealing cracks and hollows in structural elements. The paper provides a summary analysis of the current situation with the use of composite materials to increase the load-bearing capacity of certain structural elements. It discusses the methods for achieving multi-functionality of materials with the use of polymer-bitumen binders. It further details the procedure for the experimental studies conducted to test several composite materials introduced in a liquid polymer-bitumen mass and applied onto an adhesive polymer-bitumen tape, including the following components: graphite powder, graphite grease, cement and a mixture of graphite powder and cement. When assessing the adhesion characteristics of the samples tested, it was found that the best performance was demonstrated by the following composite materials: polymer-bitumen tape with graphite powder and a mixture of graphite powder and cement. Their adhesion characteristics were shown to be relatively equivalent by using the following two testing methods: the tear-off method with a three day holding period, and the instant adhesion measuring method. However, composite materials with a liquid polymer-bitumen basis failed to produce the desirable results. The authors are of the view that in this case the given adhesion power parameters can be achieved through changing the structure of the materials.

“…A recent calculation suggests that the typical intertube attraction is on the order of 36 kT for every nanometer of overlap between adjacent tubes, leading to cohesive energy of few thousands of kT per micrometer-long tubes [19]. Current approaches for dispersing and exfoliating bundled CNT into individual nanotubes include covalent modifications, п-п interactions, surfactant adsorption, and more [20][21][22][23][24][25][26][27][28]. Most of these methods are designed to reduce the short-range attraction between adjacent nanotubes through introduction of a repulsive interaction of similar strength.…”

Carbon nanocomposites have received a great deal of attention in recent years in view of their special properties such as low density, superior thermal and mechanical properties. However, poor dispersion and poor interfacial bonding limit the full utilization of carbon nanotubes as reinforcing agent in polymer nanocomposites. This paper presents an approach developed for production of polymer matrix nanocomposites with uniformly distributed multi-walled carbon nanotube (MWCNT). This approach involves preparation of a stable MWCNT in Nafion ® polymer matrix followed by fabrication of MWCNT-Nafion ® nanocomposite via a novel electrochemical co-deposition process (ECD). The ECD process introduced here follows the similar basic principles of traditional electrophoretic deposition. Morphology and microstructure of fabricated MWCNT-Nafion ® nanocomposite sheets were evaluated through scanning electron microscopy(SEM). The mechanical performance of the nanocomposite was assessed by tension tests per ASTM D3039. Deposition of the MWCNT-Nafion ® nanocomposite on an aluminum sheet produced significant gains in the tensile properties of the sheet. This finding confirms that uniform dispersion of MWCNT in a polymer matrix can produce nanocomposites with desired mechanical properties.
