Impact of nanoparticle surface modification on the mechanical properties of polystyrene-based nanocomposites

Abstract

A two-step modification strategy is applied to tailor the particle–matrix interface in zirconia nanoparticle–polystyrene composites, achieving strongly enhanced mechanical properties.

Made to measure: Easy Synthesis and Characterization of Nanocomposites with Tailored Functionalities for Chemistry Education

“…If the latter are not only finely distributed in the matrix but also covalently bonded to the polymer via functionalized surfaces, the crosslinking of the particles with the surrounding matrix -and thus also the formation of cracks and scratches -can be controlled even better (Figure 1, right). Expressed in numbers, the scratch depth in the composite can be reduced by up to 50% [3,4,5]. As indicated in section 1, the advantage of using nanoparticles is that boehmite can be integrated into the polymer matrix more finely distributed.…”

“…As indicated in section 1, the advantage of using nanoparticles is that boehmite can be integrated into the polymer matrix more finely distributed. This significantly increases the probability that crack propagation in the material can be better controlled [4,5].…”

Nanokomposite selbstgemacht

“…Beispiele für diese Methode sind hier die Synthese von zwei Nanokompositen mit unterschiedlichen Anwendungsfeldern: mit Aluminiumoxid-Nanopartikeln, die Bruchund Kratzfestigkeit des Komposits steigern, 1) sowie mit Silbernanopartikeln, die antimikrobielle Eigenschaften aufweisen.…”

Stabilization of β-Galactosidase on Modified Gold Nanoparticles: A Preliminary Biochemical Study to Obtain Lactose-Free Dairy Products for Lactose-Intolerant Individuals

“…The advancement in the synthesis procedure makes it possible to formulate nanoparticles with precise control over physico-chemical and optical properties that are desired for specific clinical or biological applications [ 21 ]. Surface modification technology has further added impetus to the specific applications of nanoparticles by imparting them the desirable characteristics [ 22 ]. Such strategies involve introduction of ligands on the surface of nanoparticles via simple chemical reactions to stabilize the nanoparticles against agglomeration and providing compatibility with other phases in a self-organized manner [ 23 ].…”
