Effect of dispersion capability of organoclay on cellular structure and physical properties of PMMA/clay nanocomposite foams

Rigid polyurethane foams incorporated with phase change materials: A state-of-the-art review and future research pathways

“…It is verified that small amounts of well dispersed nanoparticles can serve as nucleation sites to facilitate the bubble nucleation process and lead to the achievement of macroscopic mechanical enhancement in thermoset foams, due to the nanoscaled dimension, the high aspect ratio, and the large surface area [40,41]. In addition, it has been shown that small amounts of nanoparticles can greatly reduce the cell size of the foams and increase the cell density, which will lead to a reduced thermal conductivity and be beneficial by improving compressive strength as opposed to neat polymer foams [42,43].…”

Structural properties of batch foamed acrylonitrile butadiene styrene/nanoclay nanocomposites

“…Okamoto et al used organically modified layered silicates as nucleating agents to produce polypropylene (pp)/clay composites (Okamoto et al 2001). Yeh et al studied the effect of dispersion capability of organoclay on cellular structure and physical properties of poly methyl methacrylate (PMMA)/ clay nanocomposite foams and demonstrated that the well-dispersed clay particles in the polymer matrix cause an increase in cell density, a decrease in cell size, and also an increase in mechanical strength of PMMA/ clay nanocomposite foams (Yeh et al 2009). Mamaghani Shishavan et al studied the mechanical properties and composition capability of ABS/PMMA/clay nanocomposites and showed that ABS and clay nanoparticles with PMMA could be compounded and their mechanical properties are stronger than those of the pure ABS (Mamaghani Shishavan et al 2014).…”

Recent Developments of Foamed Polymer/Layered Silicates Nanocomposites

“…Besides, PMMA composites with organoclay were characterized by a decreased value of dielectric constant and a slightly increased thermal conductivity [87].…”
