Organophilic clays are used as components in petroleum fluids, lubricants, paints, adhesives, cosmetics, and others. This requires products that are increasingly pure with homogeneous properties, which are hardly found in natural clays. Synthetic cla

Publikováno v: ACS Applied Nano Materials. 3:11510-11516

The inorganic halloysite nanotube (HNT) is a promising type of naturally occurring fillers with many important uses in different fields. An HNT has a relatively low content of hydroxyl groups on it...

In this study polyester-based thermoplastic polyurethane (TPU) samples were annealed at 110 degrees C for 0, 8, 16, and 24 h. To elucidate the relationship between the hard and soft phase separation and the shape memory properties, the samples were c

The inorganic nanotube halloysite (HNT) is a promising type of natural occurring filler for polymers. Its characteristics, such as high aspect ratio (10–50), small size, and high strength (elastic modulus—140 GPa) suggest that HNTs have a potenti

The aim of this work is to study the properties of systems based on polypropylene (PP) and commercial organophilic montmorillonite, prepared by melt intercalation. Because of the non polar character of PP, the polypropylene-graft-maleic anhydride (PP
