Renewable dielectric materials have attracted the attention of industries and stakeholders, but such possess limited properties. This research focused on studying polylactic acid (PLA)/cellulose acetate (CA) blends produced by 3D printing to facilitate their integration into electrical insulation field. The findings showed that a blend containing 40% CA weight had constant 2.9 an conductivity 1.26 × 10−11 S·cm−1 at 100 Hz 20 °C while exhibiting better mechanical rigidity in rubbery state than neat PLA. In addition, it was possible increase insulating effect reducing infill ratio cost reduced differential scanning calorimetry, broadband spectroscopy, dynamic analysis results PLA plasticizer energy required for relaxations. These preliminary demonstrated benefits using combination PLA, CA, applications.

The development of cellulose-reinforced biomaterials appears to be an attractive approach for the production sustainable materials with good mechanical properties. Although 3D printing has become popular, there is very little feedback regarding their use in electrical insulation applications. This study aims propose bio-nano-composites containing polylactic acid (PLA), microcrystalline (MCC) and nanocrystalline (NCC) cellulose by fused filament fabrication (FFF) influence process, content filler size on dielectric properties was investigated. addition cellulosic fillers, considering high polarity, increased constant (ε'), loss (ε''), as well AC conductivity (σAC) composites. Cellulosic fillers also crystallization rate materials. At equivalent content, highest polarization potential were observed NCC-based composites attributed nanofiller's better dispersion available specific surface area. Finally, process affects all measured properties, due a combined effect (lower crystalline voids presence). porosity at 2.5 % neat PLA progressively from 3.1 5.8 cellulose-based These findings showed benefits provided FFF technology biocomposites while noting some needed thermomechanical such
