Temperature dependent electrical properties of thermoplastic polypropylene nanocomposites for HVDC cable insulation

IEEE transactions on dielectrics and electrical insulation, 2019
Polypropylene has been regarded as a potential recyclable insulation material for HVDC cable, which is beneficial to improve the working temperature and transmission capacity of HVDC cables.

Polypropylene nanocomposite with polypropylene-grafted graphene

Macromolecular Research, 2016
A method for grafting polypropylene (PP) onto graphene oxide (GO) surfaces was successfully established by functionalizing GO with (3-aminopropyl)triethoxysilane (NH2-t-GO) and grafting maleic-anhydride-grafted PP (MAPP) on NH2-t-GO (MAPP-g-GO). The PP/GO nanocomposites were prepared by compounding MAPP-g-GO with virgin PP.

Polypropylene–polysilsesquioxane blends

European Polymer Journal, 2010
Abstract This paper deals with the preparation of PP/polysilsesquioxane blends and their study to investigate silsesquioxane dispersion, mechanical properties, thermal stability and combustion properties by means of a number of techniques, such as SEM, XRD, Rheology, TGA, DSC, Cone Calorimeter tests and LOI. Polysilsesquioxane with different organic

Effects of Lignin Content on Mechanical and Thermal Properties of Polypropylene Composites Reinforced with Micro Particles of Spray Dried Cellulose Nanofibrils

ACS Sustainable Chemistry and Engineering, 2018
In this work, the use of microsized cellulosic particles obtained from spray dried cellulose nanofibrils with high lignin content (>20 wt %) were explored for the first time as reinforcement in polypropylene (PP) composites.

Microstructure of polypropylene

Progress in Polymer Science, 2001
Abstract For over thirty years after the discovery of stereoselective olefin polymerization in 1954, the word ‘polypropylene’ has meant, both scientifically and commercially, little else than the predominantly isotactic polymer achievable with the classical heterogeneous Ziegler–Natta catalysts.

Polypropylene/organoclay nanocomposites compatibilized with hydroxyl‐functional polypropylenes

Journal of Polymer Science Part B: Polymer Physics, 2005
AbstractThe properties of polypropylene composites can be tailored through the use of nanoclay fillers. The effectiveness of a metallocene‐catalyzed hydroxyl‐functional polypropylene in the compatibilization of polypropylene layered nanosilicate composites was studied, and the results were compared with those for a commercial maleic anhydride ...
