“…This might be due to the agglomeration of clay at higher loading. Similar agglomeration was observed by Baishya and Maji 21 while examining the TEM micrograph of nanoclay-loaded wood/starch composite. TEM results suggested that MMT layers were delaminated and well dispersed in 5 phr MMT-loaded composites…”

Naturally available waste biomass rice husk (RH) was modified and used to prepare nanocomposites with polyvinyl chloride (PVC) and montmorillonite clay (MMT) in a green pathway of melt blending. Three different percentages of MMT were introduced into the RH/PVC composites and their effects on various properties of composite were examined. The interaction between PVC, RH, polyethylene-grafted maleic anhydride, and MMT clay in the nanocomposite (RHPNC) was studied by Fourier transform infrared spectroscopy and thermal properties were studied using dynamic mechanical analysis and thermogravimetric analysis. Universal testing machine and limiting oxygen index flammability tester were used to study the mechanical and flame retardency properties, respectively. The delamination of MMT layers and surface morphology of clay-incorporated nanocomposites were analyzed by X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy. Surface of 5 phr (parts per hundred) MMT-loaded composites appeared smoother than those of composites containing 2 or 5 phr MMT. RHPNC with 5 phr MMT showed an overall improvement in mechanical, thermal, and flame-retardant properties. Composites containing 5 phr MMT showed a decrease in water uptake capacity compared to either 2 phr or 10 phr MMT-loaded composites.

“…Baishya et al [ 54 ] used starch and coniferous wood as raw materials and water as a solvent to prepare biomass-based nanocomposites. To prepare wood starch nanocomposites, wood starch nanocomposites (WSNC) were prepared using methyl methacrylate (MMA)-modified starch, dimethyl dihydroxyethylurea (DMDHEU), wood flour, glycerol, and montmorillonite (MMT) as raw materials.…”

Wood is widely used as a construction material due to its many advantages, such as good mechanical properties, low production costs, and renewability. However, its flammability limits its use in construction. To solve the problem of wood flammability, the most common method to improve the fire safety of wood is to modify the wood by deep impregnation or surface coating with flame retardants. Therefore, many researchers have found that environmentally friendly and low-cost biomass materials can be used as a source of green flame retardants. Two aspects of biomass-based intumescent flame retardants are summarized in this paper. On the one hand, biomass is used as one of the three sources or as a flame-retardant synergist in combination with other flame retardants, which are called composite biomass intumescent flame retardants. On the other hand, biomass is used alone as a feedstock to produce all-biomass intumescent flame retardants. In addition, the potential of biomass-based materials as an environmentally friendly and low-cost FR source to produce high-performance biomass-based flame retardants with improved technology was also discussed in detail. The development of biomass-based intumescent flame retardants represents a viable and promising approach for the efficient and environmentally friendly production of biomass-based flame retardants.
