      abstract     = {A water-soluble hydroxypropyl cellulose (HPC) polymer
                      matrix has been filled with different weight percentages
                      $(wt.\%)$ of multiwalled carbon nanotubes (MWCNTs),
                      fullerenes C60, fullerenols C60(OH)24, and their
                      combinations. We study the potential of the 0D nanoparticles
                      for improving electrical properties of the conductive MWCNT
                      network in a biocompatible matrix. Physicochemical effects
                      of fillers content, both individually and in combinations
                      (MWCNTs/C60 and MWCNTs/C60(OH)24), for these composite
                      systems, have been investigated. The performed SAXS analysis
                      shows improved nanofiller dispersion for films with two
                      fillers. The electrical percolation threshold (Pc) in MWCNTs
                      composites occurs at ≈1.0 $wt.\%.$ A synergistic effect
                      for binary filler composites on the electrical conductivity
                      has been evaluated by keeping a constant amount of 0.5
                      $wt.\%$ MWCNTs (σ ≈ 3 × 10−9 S·m−1) and increasing
                      the amount of C60 or C60(OH)24. A large increase in the
                      electrical conductivity is obtained for the bifiller
                      composites with 0.5 $wt.\%$ MWCNTs and 1.5 $wt.\%$ of
                      C60(OH)24, reaching σ ≈ 0.008 S·m−1. Further, the
                      sensing properties of 4.0/1.0 MWCNT/C60 nanocomposites were
                      demonstrated by measuring both piezoresistive (PR) and
                      thermoresistive (TR) responses. The combination of
                      semiconductive fullerene/fullerenols combined with MWCNTs
                      allows obtaining more homogeneous composites in comparison
                      to single MWCNTs composites and also gives possibilities for
                      tuning the electrical conductivity of the system. Overall,
                      it is demonstrated that the use of bifillers with a water
                      soluble biopolymeric matrix allows the development of
                      eco-friendly high-performance electroactive materials for
                      sustainable digitalization.},
