“…However, the enthalpy of glass transition (ΔH G ) has increased significantly to 1.716 J/g as compared to 0.0261 j/g of neat PLA. The decrease in T G shows the crystalline orientation at low temperature (63.2 °C) due to the physical interlocked PP [ 29 , 40 ] and the increase in ΔH G shows the partial compatibilization [ 12 , 29 ]. Furthermore, the melt crystallization of non-printed blend pellets appears with distinct small steps on right hand side compared to the unimodal melt crystallization in neat PLA as shown in a magnified image ( Figure 6 ).…”

The materials for large scale fused filament fabrication (FFF) are not yet designed to resist thermal degradation. This research presents a novel polymer blend of polylactic acid with polypropylene for FFF, purposefully designed with minimum feasible chemical grafting and overwhelming physical interlocking to sustain thermal degradation. Multi-level general full factorial ANOVA is performed for the analysis of thermal effects. The statistical results are further investigated and validated using different thermo-chemical and visual techniques. For example, Fourier transform infrared spectroscopy (FTIR) analyzes the effects of blending and degradation on intermolecular interactions. Differential scanning calorimetry (DSC) investigates the nature of blending (grafting or interlocking) and effects of degradation on thermal properties. Thermogravimetric analysis (TGA) validates the extent of chemical grafting and physical interlocking detected in FTIR and DSC. Scanning electron microscopy (SEM) is used to analyze the morphology and phase separation. The novel approach of overwhelmed physical interlocking and minimum chemical grafting for manufacturing 3D printing blends results in high structural stability (mechanical and intermolecular) against thermal degradation as compared to neat PLA.

“…Larguech et al studied the dielectric properties of poly(lactic) acid (PLA)/poly(butylene succinate) (PBS) blends reinforced with jute fibers using broadband DS between 20 and 140 C and frequency ranging from 0.1 Hz to 1 MHz. 86 Direct current (DC) conductivity, α-mode relaxations, and Maxwell-Wagner-Sillars (MWS) interfacial polarization effect were observed in PLA. In addition to these, β relaxation and interfacial polarization were also observed in PLA/PBS blend stemming from PLA and semi-crystalline PBS, respectively.…”

This review provides an in‐depth analysis of the electrical responses and relaxation behaviors of various polymeric materials including fiber‐reinforced polymer composites, polymer nanocomposites (PNC), and nanofiller‐reinforced polymeric films and coatings using dielectric spectroscopy (DS). The underlying theory of DS, corresponding instrumentation, various dielectric parameters, relevant equations, interpretations, and polarization mechanisms are thoroughly explored. The impact of synthetic and natural fibers and a diverse range of nanofillers on the dielectric responses and relaxation mechanisms of fiber‐reinforced composites, and PNC and films, respectively, are also examined. For each summarized article, we provide an overview of the composite or film preparation, followed by concise explanations of the dielectric behaviors under diverse conditions, including variations in temperature, frequency, moisture levels, fiber/filler ratios, and chemical treatment. In essence, this review contributes to a nuanced understanding of the intricate relationship between material structure, properties, and performance via DS data interpretation across a spectrum of scenarios.

“…In addition, the presence of moisture can significantly increase the loss factor of PBS, especially at high frequencies. [56][57][58][59] Several physical characteristics can influence the dielectric properties of PBS, including the degree of crystallinity, the molecular weight, and the presence of additives or fillers. For instance, as the degree of crystallinity of PBS increases, its dielectric constant tends to decrease, which is due to the lower permittivity of the crystalline regions than the amorphous regions.…”
