In contrast to the other carbon fillers which require complex synthetic production methods, biochar which is a porous carbonaceous solid residue can be produced by slowly pyrolysing the biomass at a high temperature ranging from 500 to 700 C. 8 Similar to other carbon fillers, biochar is porous, thermally stable, has large specific surface area, and consists of several functional groups ...

However, no attempt has been made to assess the effects of soil conditioners such as biochar (BC), biopolymer (BP) or polyacrylamide (PAM) on plant residue decomposition. We assessed the effects of BC, synthesized BP and anionic PAM on the decomposition of 14 C-labelled maize residues and on their stabilization in aggregate fractions in sandy and sandy loam soils.

In this study, we assessed the effects of anionic polyacrylamide (PAM), synthesized biopolymer (BP), and biochar (BC) on the decomposition of 14 C-labeled maize residue in sandy and sandy loam soils. Specifically, PAM and BP with or without 14 C-labeled plant residue were applied at 400 kg ha -1 , whereas BC was applied at 5000 kg ha -1 , after which the soils were incubated for 80 days at 22 °C.
Get PriceHow does biochar particle size affect mechanical properties of bioplastic composites?
Biochar (BC) particle size affects mechanical properties of bioplastic composites. Certain BC loading and particle size can improve strength (1.5×) vs control. BC particle size affects the apparent viscosity of a composite while mixing. Smaller particle size and higher loadings increased the modulus of elasticity.
How does biochar affect the viscosity of polymer composites?
Biochar in polymer composites improves the viscosity of the composites; additionally, the biochar particle size has massive effects on the flow behavior and leads to a severe increase in shear viscosity to around 5000 Pa-s . Biochar with smaller particle size diameter has shown lower viscosity compared to samples with large particle diameters.
Does biochar affect the mechanical properties of nylon composites?
The shape and size of filler can greatly alter composite properties. It is often observed that the higher the aspect ratio of filler the better the properties of the composite. The effect of variable particle size of biochar on the mechanical properties of nylon composites was studied by Ogunsona, Misra, and Mohanty 2017 .
Can biochar be used as a filler in polymer composites?
Biochar is relatively inert compared to unprocessed natural fillers and can serve as filler in polymer composites fortifying the composites and with further calibration, additional properties like electrical conductivity can also be introduced in the composites, as per requirement.
Does biochar improve thermal properties of polymer composites?
In some studies, the increase in melting temperature has been reported and in some a decrease in melting and crystallization enthalpies have been reported. All in all, the addition of biochar to the polymer composites has indicated improved thermal properties.
Does biochar carbonization affect tensile modulus of polymer composites?
Biochar filler particles with softer phase of hardening agent increase the degree of stress transfer to filler particles [78, 86]. The temperature of biochar carbonization affects the mechanical properties and the tensile modulus of polymer composites. 5. Use of Filler Materials in Polymer Composites: Effects and Limitations
