Stress relaxation in hematite nanoparticles-polystyrene composites

Abstract

The viscoelastic behavior of a polystyrene matrix filled with hematite nanoparticles was investigated using the stress relaxation method. An increase in the elastic moduli of the composites, as well as in the magnitude of stress relaxation was found with increasing content of the inorganic phase. The obtained results are discussed in terms of a one‐process model.

An easy approach to fabricating HgS/chitosan nanocomposite films and their ability to sense triethylamine

“…Many studies have used chitosan (CS) as a nanocomposite matrix [2][3][4][5]. Nanoparticles such as metals [6,7], metal sulfides (CdS) [8,9], metal oxide [10] and nanotubes [11] have also been used as nanofillers. Dif ferent properties are obtained depending on the particle dimensions, shape, and chemical structure.…”

Preparation and properties of hybrid monodispersed magnetic α-Fe2O3 based chitosan nanocomposite film for industrial and biomedical applications

“…Composite films comprising nanometer-sized metal oxide, semiconductor, and magnetic particles dispersed in a solid polymer matrix [1][2][3][4] have received an increased attention due to a broad range of the exceptional properties namely process imaging, biosensor, disease diagnosis, etc. This so-called polymer nanocomposites combine the excellent functional properties of nanoparticles with desired properties of host polymers.…”

Polystyrene/hematite composites: thermal degradation kinetics

“…Therefore, it is essential to examine and understand influence of incorporation of semiconductor particles on physical and chemical properties of polymer matrix. [7][8][9][10] There are number of studies devoted to inorganic/organic composites with polystyrene (PS) as a matrix, 2,3,6,7,[11][12][13][14][15] which is well-known representative of vinyl polymers. For this group of polymers, it is typical that, upon heating, degradation starts rather easily due to the weak link sites inherent with polymer chain.…”
