2. 1. Inorganic and organic polymer-grafted nanoparticles : their nanocomposites and characterization

   Author : Carmen Cobo Sanchez; Eva Malmström; Henrik Hillborg; Anna Barros Timmons; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Si-ATRP; ATRP; polyelectrolytes; rGO; aluminium oxide; silica; CNF; CNC; PCL; LDPE; EBA; nanocomposites; matrix-free; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. READ MORE
