Fyzikální chování nanokompozitů PE v závislosti na obsahu dřevěných vláken
Kokta, B. V. ; Kwei-Nam, L. ; Fortelný, Ivan ; Lednický, František ; Kruliš, Zdeněk
We investigated the formation of an optimal compatibilizing system for the hybride composite polyethylene -birch wood fibers-nanoclay by combining basic principles for compatibilization, i.e. addition of maleated polyethylene and peroxide.
Kompozity PMMA s anorganickým plnivem: interpretace vlivu struktury matrice za přítomnosti plniva
Dušková, Miroslava ; Dušek, Karel ; Zelenka, J.
The study showed that the properties of a glassy composite with crosslinked matrix adhering to the rigid filler particles are sensitive to the polymer network structure of the matrix . It was proved by morphological, swelling and mechanical studies that the adhesion between the crosslinked poly(methyl methacrylate) matrix and the ATH filler is maintained in the swollen state and during small-strain. In the swollen state or at temperatures about 60 °C above Tg, the mechanical relaxations are relatively fast and equilibrium can be reached within approximately one hour. A model of equilibrium swelling constrained by surfaces of various geometries has been developed based on statistical thermodynamics of (Gaussian) networks.
