Recent advances in shape memory polymers and composites : a review
TL;DR: Shape memory polymers (SMPs) belong to a class of smart polymers, which have drawn considerable research interest in recent years because of their applications in microelectromechanical systems, actuators, for self healing and health monitoring purposes, and in biomedical devices as mentioned in this paper.
Journal ArticleDOI
Clay‐reinforced epoxy nanocomposites
TL;DR: In this article, the authors used a conventional diglycidyl ether of bisphenol A (DGEBA) epoxy, cured with diethyltoluene diamine (DETDA), and characterized the nanocomposites by dynamic mechanical analysis.
Journal ArticleDOI
Rubber Toughened Epoxy
Debdatta Ratna,Ajit K. Banthia +1 more
TL;DR: In this paper, the development of various functionalized liquid rubber-based toughening agents and core-shell particles are discussed critically in a review of recent advances in the development.
Journal ArticleDOI
Nanocomposites based on a combination of epoxy resin, hyperbranched epoxy and a layered silicate
TL;DR: In this paper, an epoxy/clay nanocomposites have been prepared using an diglycidyl ether of bisphenol A (DGEBA) epoxy and its blend with a functionalized hyperbranched polymer (HBP), which is confirmed by wide angle X-ray diffraction and transmission electron microscopy (TEM) analysis.
Journal ArticleDOI
Poly(ethylene oxide)/clay nanocomposite: Thermomechanical properties and morphology
TL;DR: In this article, a solution intercalation method using chloroform as a solvent was used to extract poly(ethylene oxide) (PEO)/clay nanocomposites.
