Nano-cellular foams were successfully produced from nanostructured PMMA/block copolymer blends using a gaseous CO2 foaming process. The use of block copolymer as potential nucleating agents has allowed the obtaining of nano-cells with cell densities higher than 1014 cm−3. Optimization on PMMA matrix formulation composed of blends of PMMAs with different molar masses, combined with the optimization...
ABS nano-cellular foams have been produced using a gaseous CO 2 foaming process. ABS materials have been investigated in this study because of their specific morphologies, which can increase the nuclei density by creating heterogeneous nucleation near the interfaces between acrylonitrile–styrene and butadiene phases during the foaming process. This study focuses on the foaming of different...
PMMA-based nano-cellular materials were produced using a gaseous CO 2 foaming process. PMMA has been investigated because of its CO 2 -philic behaviour, which allows high CO 2 uptake during the foaming process and facilitates the nucleation phenomenon. Nevertheless, one way to further increase the nucleation rate during the foaming process is to create a heterogeneous nucleation...
