Another way to get dispersed CNTs is by combined CNTs with IL, which obtains some new materials “soft materials”.
In other words BMIMBF4 acts as both a dispersing agent for MWCNTs and a curing initiator for PU foam [5]. 2.0 Methodology Materials.

Introduction The human bones are the organic/inorganic composite materials, which is composed of hydroxyapatite (HAP) and protein with nanometer sizes.
Poor mechanical properties of pure HAP materials such as the lower strength and tenacity would lead to the problems of loosening, transferring and fracture for the materials implanted in vivo [1,2].
Experimental Materials Antheraea pernyi cocoon came from Henan province, China.
