Extra dry toluene

E-glass fibers (GFs) were used in this study with an average diameter of 18 μm produced at the Leibniz Institute of Polymer Research Dresden without any sizing agent. MWCNTs (Nanocyl, NC 7000, Sambreville, Belgium) were received from Nanocyl S.A. (Sambreville, Belgium) with a carbon purity of >90%, average length 1.5 µm and diameters around 10 nm. For the GF silanisation, a 3-aminopropyltriethoxysilane (γ-APS, 98%) was supplied by ABCR (Karlsruhe, Germany). Hydrogen peroxide, ammonium hydroxide (28%), sulfuric-nitric acid, thionyl chloride (SOCl₂), absolute ethanol (99.5%), dichloromethane, acetone, extra dry toluene, tetrahydrofuran (THF), dimethylformamide (DMF), tetraethyl orthosilicate (TEOS, 97%), polyethyleneimine (PEI) of low molecular weight (M_n= 600 g/mol), ethyl acetate, tri(ethylene glycol) (TREG, 99%) and Iron(III) acetylacetonate (Fe(acac)₃, 97%) were purchased from Sigma-Aldrich (Steinheim, Germany). The polymer that has been used was a DGEBA-based epoxy resin with an amine-based hardener (resin EPR L20 and hardener EPH 960) at a resin to hardener weight ratio of 100:34 (Hexion Specialty Chemicals, Stuttgart GmbH).

Iron(III)
acetylacetonate (99.99%), cobalt(II)
acetylacetonate (99.99%), oleylamine (OAM, > 70%), benzyl ether
(BE,
technical grade 99%), oleic acid (OAC, technical grade, 90%), 4,4′-dinonyl-2,2′-bipyridine
(dNbipy, 97%), copper(I) bromide (Cu(I)Br, 99.9%), p-toluene sulfonyl chloride (TsCl, 99%), methyl methacrylate (MMA,
99%), hydrochloric acid (HCl), nitric acid, extra dry toluene (99.99%),
extra dry diethyl ether (99.99%), hexane, ethanol, tetrahydrofuran,
and acetone were purchased from Sigma-Aldrich. 1,2-Hexadecandiol (99%)
was purchased from TCI. 2-(4-chlorosulfonylphenyl)ethyltrichlorosilane
(CTCS, 50% solution in CH₂Cl₂) was purchased
from ABCR. P(VDF-TrFE) (65–35%) was purchased from Solvay and
used as received.

Toluene extra dry, 3-(trimethoxysilyl)propyl methacrylate, acrylamide, ammonium persulfate, NN′-methylbis(acrylamide), NNN′N′-tetramethylethylene diamine, hexamethyldisilazane, sylgard 184 PDMS, alyl bromide and PEG di thiol were all purchased from Sigma Aldrich. Aqualon sodium CMC was purchased from Ashland Chemicals.
