“…This peak also showed a physical reaction that occurred between SKNC and PVA (Voronova et al 2015). The peak between 1000-1100 cm − 1 region was for the Si-O-Si bond that overlapped due to Si-SKNC moiety (Kim et al 2019). This shows that the silylation treatment from APTES on the SKNC surface still exist even after being mixed and added together with PVA.…”

Improvement in thermal stability of nanocellulose was done with silanization treatment, which started with the treatment of silylated kenaf nanocellulose (SKNC) using 3-aminopropyltriethoxysilane (APTES) in alcohol solution at 25°C with pH 4 within 4 hours. Then, SKNC with varied content from 0.5 to 2% (w/w) was reinforced in poly(vinyl alcohol) (PVA). The SKNC was characterized by FT-IR, XRD, TEM, and TGA. The peak at 1571 cm− 1 corresponding to N-H bending vibration was observed on SKNC spectra indicating a successful silane treatment follow-up by a reduction of peak 1642 and 1425 cm− 1, respectively. The crystallinity index for SKNC was increased to 70.34% as compared with KNC (61.73%). TEM showed a needle-like structure for both SKNC and KNC. The interaction between SKNC and PVA was characterized by FT-IR with an increment of peak 1089 and 1028 cm− 1, which shows the physical interaction that occurred between PVA and SKNC. The dispersion of SKNC was well homogenous as observed in FESEM. SKNC exhibited good thermal stability and a less amount of char was formed at 700°C compared to kenaf extractive free. Furthermore, TGA demonstrated improvement after addition of 2% SKNC into PVA as well as DSC increased the melting point of PVA.

“…During the cone calorimetry test, the samples exhibited a low heat release rate (HRR) and smoke production rate (SPR), indicating a high flame retardancy and a relatively low environmental impact. Kim et al 71 conducted a study to reduce smoke emission during combustion by adding silylated and nano-fibrillated cellulose (Si-NFC) to polyurethane foam (PUF) containing tris(2-chloropropyl) phosphoric acid (TCPP). The thermal properties of the composite foam were investigated via thermogravimetric analysis and limiting oxygen index (LOI) and cone calorimeter tests.…”

“…Kim et al have used tris(2-chloropropyl) phosphate (TCPP) and silylated methyltrimethoxysilane (MTMS) NFC (Si-NFC) as additives for synthesis PU foam with improved FR features [110]. According to cone calorimetry, presence of 5 wt% of Si-NFC resulted in the pHRR decreased from 199 kW/m 2 to 159 kW/m 2 and smoke production rate (SPR) from 0.089 m 2 /s to 0.066 m 2 /s for neat PU foam and modified respectively.…”

The enormous potential of renewable bioresources is expected to play a key role in the development of the EU’s sustainable circular economy. In this context, inexhaustible, biodegradable, non-toxic and carbon-neutral forest-origin resources are very attractive for the development of novel sustainable products. The main structural component of wood is cellulose, which, in turn, is the feedstock of nanocellulose, one of the most explored nanomaterials. Different applications of nanocellulose have been proposed, including packaging, functional coatings, insulating materials, nanocomposite fields among others. However, the intrinsic flammability of nanocellulose restricts its use in some industries where fire risk is a concern. This paper overviews the most recent studies of the fire resistance of nanocellulose-based materials, focusing on thin films, coatings and aerogels. Along with effectiveness, increased attention to sustainable approaches is considered in developing novel fire-resistant coatings. The great potential of bio-based fire-resistant materials, combined with conventional non-halogenated fire retardants FRs, has been established. The formulation methods, types of fire retardants and their action modes, and methods used for analysing fire retardancy are discussed in the frame of this overview.
