Mechanical properties of nylon 6-clay hybrid
Yoshitsugu Kojima,Arimitsu Usuki,Masaya Kawasumi,Akane Okada,Yoshiaki Fukushima,Toshio Kurauchi,Osami Kamigaito +6 more
TL;DR: In this paper, the properties of nylon 6-clay hybrids, such as molecular composites of nylon and silicate layers of montmorillonite and saponite, NCH's and NCHP's, respectively, have been synthesized.
Journal ArticleDOI
Synthesis of nylon 6-clay hybrid
Arimitsu Usuki,Yoshitsugu Kojima,Masaya Kawasumi,Akane Okada,Yoshiaki Fukushima,Toshio Kurauchi,Osami Kamigaito +6 more
TL;DR: In this paper, the carboxyl and amino end groups were attributed to ammonium cations (-NH3+) of nylon molecules, because the difference agreed with the anion site concentration of the montmorillonite in NCH.
Journal ArticleDOI
Preparation and Mechanical Properties of Polypropylene−Clay Hybrids
TL;DR: In this paper, the dispersibility of 10-A-thick silicate layers of the clays in the hybrid was investigated by using a transmission electron microscope and X-ray diffractometer.
Journal ArticleDOI
Swelling behavior of montmorillonite cation exchanged for ω-amino acids by ∊-caprolactam
Arimitsu Usuki,Masaya Kawasumi,Yoshitsugu Kojima,Akane Okada,Toshio Kurauchi,Osami Kamigaito +5 more
TL;DR: In this article, a model where amino acid molecules were arranged perpendicular to silicate layers and ∊-caprolactam molecules filled the space between them was proposed to obtain nylon 6-clay hybrid, a molecular composite of nylon 6 and montmorillonite.
Journal ArticleDOI
Synthesis of nylon 6-clay hybrid by montmorillonite intercalated with ε-caprolactam
Yoshitsugu Kojima,Arimitsu Usuki,Masaya Kawasumi,Akane Okada,Toshio Kurauchi,Osami Kamigaito +5 more
TL;DR: In this paper, a nylon 6 clay-hybrid was synthesized by montmorillonite intercalated with 12-aminolauric acid and 6-aminocaproic acid.
