“…Much attention has been focused recently on cellulose‐based organic fillers and on lignin . Combining the lignin macromolecule, rich in various functional groups, with a commonly used inorganic support, offering particularly high chemical and thermal stability, enables the formation of an innovative hybrid material with improved physicochemical properties compared with those of the separate precursors (SiO 2 and lignin).…”

A novel functional silica/lignin hybrid material as a potential bio-based polypropylene filler

2014

A functional silica/lignin hybrid filler was obtained using a process of mechanical grinding of precursors (Syloid®244 silica and kraft lignin). The product underwent comprehensive physicochemical and dispersive–morphological analysis. The silica/lignin hybrid has good homogeneity and a surface area of 164 m2/g. The effectiveness of combination was confirmed by Fourier transform infrared spectroscopy and elemental analysis. The high electrokinetic stability (over almost the whole of the analyzed pH range) and above all the thermal stability of the resulting material (mass loss equal to 12%) indicate its potential use as a polypropylene (PP) filler. Experiments showed that the incorporation of a small amount of silica/lignin hybrid filler into PP may substantially influence its elongation at break and notched impact strength. Especially at low concentrations of silica/lignin filler (below 5 wt%) an exceptional set of mechanical properties was obtained. The addition of larger amounts of the filler was found not to bring any further improvement. POLYM. COMPOS., 36:913–922, 2015. © 2014 Society of Plastics Engineers

“…The low peak intensity of foamed PP is due to the large cavities formed during foaming 37 . The SFs restrict the free mobility of the amorphous PP polymeric chains and act as nucleating agents thereby facilitating crystallization 38 . Consequently, with an increase in the fiber concentration, the crystallinity (%) χ c increases in the foamed composites 39 …”

The current research aims to develop a sound‐absorbing material from polypropylene (PP) and sisal fibers (SFs). The study explores the foam processability of PP/SF composites with near‐critical fiber length, employing supercritical CO2‐assisted batch foaming technology. Optimized foam processing conditions were determined to be 145°C, 100 bar, and 15 min saturation time. These conditions resulted in foams with the lowest density, maximum volume expansion ratio and an overall microcellular structure. Notably, increasing the fiber concentration significantly enhanced the compressive properties, exhibiting a remarkable 3000% improvement with the addition of 40 wt% SFs. Dynamic mechanical analysis further revealed improved dampening properties of the composites after foaming. Moreover, the incorporation of SFs led to an increase in the noise reduction coefficient, while foaming additionally improved the sound absorption properties. This renders the material highly applicable for soundproofing purposes. Thus, produced PP/SF microcellular foams offer properties that can potentially be used to produce lightweight structural components for acoustic absorption applications.

Bagasse agave tequilana fibres (ATF), an abundant by-product of Mexican tequila production, were characterised, treated and investigated as a reinforcement and filler material for polylactic acid (PLA) green composites.Two fibre pre-treatments were investigated: alkali (8% NaOH solution) and enzymatic (0.4% Pectate lyase solution). Composites pellets of 20, 40 and 60 % (w/v) of ATF in PLA were manufactured using extrusion moulding. Press moulding was used to fabricate samples composite plates. Tensile, flexural, impact and water absorption properties were investigated on machined samples.
