Phase behavior and water vapor transport in BIONOLLE/polymethylmethacrylate blends

, 2001
The miscibility of blends prepared from amorphous polymethylmethacrylate (PMMA) and a semi-crystalline biodegradable polybutylene succinate-adipate polyester (BIONOLLE 3000) has been studied. Using methods such as microscopic observation, lowering of T m

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...

Wettability of a Polymethylmethacrylate Surface by Fluorocarbon Surfactant Solutions

Chemistry
To clarify the adsorption behavior of fluorocarbon surfactants on PMMA surfaces, the contact angles of two nonionic fluorocarbon surfactants (FNS-1 and FNS-2) and an anionic fluorocarbon surfactant (FAS) on polymethylmethacrylate (PMMA) surface were ...
