The invention relates to a polymer composition comprising a polymer (a) and a nanoparticle filler (b), wherein the polymer composition comprises a volume percentage (vol. %) of the nanoparticle filler (b), which is Dvol vol. %, and has a center-to-center average distance, in nanometer (nm), in two dimensions (2D) and with a free radius, from one nanoparticle to its nearest nanoparticle neighbour, which is R1st nm, and wherein the polymer composition shows a dependency between said center-to-center average distance to nearest neighbour, R1st, and said volume percentage, Dvol vol. %, which is R1st=E/(Dvol+0.3)+F, wherein Dvol&#x2264;Dvol&#x2264;Dvol, E&#x2264;E&#x2264;E, F&#x2264;F&#x2264;F, and Dvolis 0.010 and Dvolis 4.4, Eis 100 and Eis 280, and Fis 50 and Fis 140; an electrical device, e.g. a power cable; and a process for producing an electrical device.

Polymer composition and electrical devices

The present invention relates to cellulose nanofibrils decorated with magnetic nanoparticles as well as a method for the preparation thereof and a material comprising the nanofibrils.

Cellulose nanofibril decorated with magnetic nanoparticles

The present invention relates to ferromagnetic materials based on nano-sized bacterial cellulose templates. More specifically, the present invention provides an agglomerate free magnetic nanoparticle cellulose material and a method of forming such magnetic nanoparticle cellulose material. Further, the magnetic nonoparticles are physically attached on the cellulose material and evenly distribute.
