High - performance rubber sealant for preventing water leaks / Morinobu Endo in Industrial & engineering chemistry research, Vol. 49 N° 20 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 20 (Octobre 2010) . - pp. 9798-9802 Titre : High - performance rubber sealant for preventing water leaks Type de document : texte imprimé Auteurs : Morinobu Endo, Auteur ; Kenji Takeuchi, Auteur ; Toru Noguchi, Auteur Année de publication : 2011 Article en page(s) : pp. 9798-9802 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Leak  Sealing  material Résumé : Considerable amounts of water are being lost due to leaks. One of the main reasons for experiencing such large water leaks is the premature failure of rubber sealants in valves. Water leaks commonly originate from the presence of chlorine ions in tap water. Here, we demonstrate that the incorporation of surface-modified and highly crystalline carbon nanotubes allows the rubber sealants to maintain their sealing properties without experiencing any distinctive degradation over a wide range of temperature and environmental conditions over their expected lifetime. It is envisaged that environmentally friendly nanotechnology will save huge amounts of energy for purifying and transporting water around the whole world.

Preparation and properties of multiwall carbon nanotubes/polystyrene-block-polybutadiene-block-polystyrene composites / Shigeki Inukai in Industrial & engineering chemistry research, Vol. 50 N° 13 (Juillet 2011)

The incorporation of MWCNTs into the SBS matrices improved their thermal and mechanical properties with appropriate flexibility. The MWCNT/SBS composites did not flow above 100 °C, and showed surprising improvements in terms of their creep properties. The results indicated the possibility of broadening their use in high temperature applications, and of significantly improving permanent strain, which are currently the main demerits ofTPE. These drastic improvements in the various properties ofMWCNT/SBS composites were assumed to have been caused by the formation of a three-dimensional structure at the interfacial phase of the SBS matrix along the MWCNTs, which we designated as a "cell structure".
