Fibrous nanofillers

Summing up the above results the author would claim that microparticles are far more efficient toughness modifiers than nanoparticles. The nanoeffects reported in numerous works should be linked with changes of the crosslink density in the interphase. The related changes are likely caused by the selective absorption of a given component of the resin by the nanoparticles. Note that this happens also when the nanoparticles are available in masterbatch form. Unfortunately, the related aspects e.g., cure kinetics, morphology development) have not yet been addressed by systematic studies. Nevertheless, platy fillers, present in both micro- and nanoscale at the same time, may be better toughener than spherical or fibrous nanofillers. Func-... 

Only few reports are available on fibrous nanofillers embedded in toughened or hybrid resins. For VEUH it was reported that both and decrease in the presence of 0.5 wt% MWCNT. Interestingly, the opposite tendency was observed for interpenetrating vinylester/EP systems as a fmiction of MWCNT content. It has to be mentioned that the cited authors did not adopt the right fracture mechanical method when studying this very ductile hybrid resin of interpenetrating network structure [156]. 

Composites are engineered materials that contain two or more constituents with different properties that remain distinct from one another within the structure. POCs are a subset of the larger polymer composites group. The increased synthesis of POCs with different additives is necessary to satisfy the industrial demand that cannot be fulfilled by pure polymers. Additive materials can be classified as micro-and nanofillers depending on the applications of the composites. The fillers may be further subdivided as natural (plant fibers) or synthetic (glass fibers, CNT, etc.), different shapes (long or short length), flaky, fibrous, and spherical or disk-like [6]. The conventional addition of filler materials lowers the cost and improves the... 

In short, this innovative procedure has opened an easy pathway for the use of CNTs in aqueous media without the use of surfactants or commonly applied oxidative treatments responsible for extensively damaging the CNT outer walls, allowing an alternative preparation of fibrous clay materials provided with conducting properties and of great interest as nanofillers for diverse polymeric matrices. 

This chapter focuses on the non-linear viscoelastic behavior of rubber composites and nanocomposites. Here, we have discussed about the effect of individual fillers (mineral fillers, nanotubes, carbon nanofillers, fibrous nanofiUers, biofillers, special structured fillers viz. nanorods, nanowires, nanoflowers etc.) on the linear/ nonlinear viscoelastic behavior of rubber composites. Moreover, as this chapter is more concerned on the non-linear viscoelastic behavior, we have also discussed the effect of hybrid fillers on the nonUnear viscoelastic behavior of rubber composites in more detail. 

The work presents results of investigations on production of nanocomposite fibrous materials via the electrospinning method. Ceramic particles which are known for their bioactivity were used as nanofillers. Process parameters of the nanocomposite fibres production were examined. Dispersion state of the nanoadditives, microstructure and bioactivity of the materials were studied. 

The presence of silica NPs assembled to fibrous clays could be of interest for their use as nanofillers in polymers reinforcement Preliminary attempts in the use of silica-sepiolite nanoarchitectures, as well as the intermediate silica-organosepiolite materials, as nanofillers of epoxy resins show a moderate mechanical improvement [57,74], Further modifications of the silica NPs assembled to sepiolite could produce organic-inorganic hybrids that can be considered as promising new functional materials for diverse applications, from sensing devices to polymer reinforcement.
