“…The band at 3296 cm -1 in Fig. 2a corresponding to the stretching vibration of O-H/N-H groups of SPI-lignin sharpened compared to that of unmodi ed lignin, presumably due to SPI breaking the inter-/intra-molecular interactions of lignin chains, forming a homogeneous structure within the matrix 31 . Additionally, two sharp peaks at 2943 cm -1 and 2859 cm -1 appeared and were assigned to the -CH 2 and -CH 3 stretching of the long aliphatic carbon chain.…”

“…5e. the structure parameters could be obtained from the analysis of the 1D correlation function curves, including the long period length (L), the transition layer length (d tr ), and the length of the crystalline layer plus transition layer (l c ) 31 . The corecrystalline layer length (d 0 = l c -d tr ) and the amorphous layer length (l a = L-l c ) were then calculated accordingly.…”

In the quest of materials that can tolerate extreme environments (i.e., aerospace, polar regions of earth), facile design of self-healing, high fatigue-resistant and multifunctional nanocomposite materials with excellent ultralow temperature toughness, especially by utilizing inexpensive and sustainable bioresources is still currently challengeable. In current study, we present a material that displays remarkable ultralow temperature toughness, shows excellent toughness (107.3 MJ•m -3 ) at − 196°C and maintains high mechanical strength in highly humid environments. This material is a spider silk-inspired, poly(vinyl alcohol) (PVA)-based, autonomous room temperature self-healable nanocomposite by complexation of boron nitride (BN), quantum dots (QDs) and soybean protein isolate grafted lignin (SPIlignin). The fabricated material, namely PVA-BN-QDs-SPI-lignin, simultaneously exhibits outstanding tensile strength (53.3 MPa), toughness (182.8 MJ•m -3 ), fatigue-resistance as well as antiultraviolet and uorescent properties and sets an impressive new record of folding-failure (900 000 times) and toughness, which are 10.6 to 45.7 times higher than other graphene-based nanocomposites. It can be impressively self-healed within only 2 minutes. Of particular interest is its facile, green, mild and inexpensive preparation method that can be easily scale up. It is believed that this work, beginning with abundant biodegradable resources, opens the door to develop biobased multifunctional materials in practical applications, such as exible wearable materials.

“…Improvement of the mechanical properties could better be attributed to the good interfacial interaction between CNFs and the carrageenan matrices and the polysaccharide structures' influence. The enhanced mechanical strength of the silane-modified macroalgae CNF films as compared to the unmodified macroalgae CNF films might be attributed to the presence of cross-linked Si-O-Si bonds of polysiloxane [4,32].…”

Hydrophilic behaviour of carrageenan macroalgae biopolymer, due to hydroxyl groups, has limited its applications, especially for packaging. In this study, macroalgae were reinforced with cellulose nanofibrils (CNFs) isolated from kenaf bast fibres. The macroalgae CNF film was after that treated with silane for hydrophobicity enhancement. The wettability and functional properties of unmodified macroalgae CNF films were compared with silane-modified macroalgae CNF films. Characterisation of the unmodified and modified biopolymers films was investigated. The atomic force microscope (AFM), SEM morphology, tensile properties, water contact angle, and thermal behaviour of the biofilms showed that the incorporation of Kenaf bast CNF remarkably increased the strength, moisture resistance, and thermal stability of the macroalgae biopolymer films. Moreover, the films’ modification using a silane coupling agent further enhanced the strength and thermal stability of the films apart from improved water-resistance of the biopolymer films compared to unmodified films. The morphology and AFM showed good interfacial interaction of the components of the biopolymer films. The modified biopolymer films exhibited significantly improved hydrophobic properties compared to the unmodified films due to the enhanced dispersion resulting from the silane treatment. The improved biopolymer films can potentially be utilised as packaging materials.

“…34 The second major weight loss of the SM adhesive started at approximately 214 C and ended at 284 C with one peak at 261 C, resulting from the decomposition of small molecules and the breakage of the peptide backbone. 35 The third stage of weight loss started at approximately 284 C with one peak at 317 C due to the degradation of soy meal matrix. 36 The modified SM adhesives showed the same trend and decomposition peak temperatures as SM adhesive.…”

Nanoparticle enhancement has been used as an effective means to improve the performance of biomass adhesives. However, there is an inevitable problem of stress concentration caused by particle agglomeration and thus the adhesive layer is susceptible to damage. Therefore, in this paper, a sol-gel method was used to generate uniformly distributed manganese dioxide (MnO 2 ) nanoparticles on the surface of diatomite (Dia) and used for the modification of soybean meal based wood adhesives. The results showed that MnO 2 nanoparticles have been successfully anchored on the surface of Dia during the sol-gel process without agglomeration. MnO 2 /Dia particles could fill in the adhesive gaps and form hydrogen bonds with soy protein molecules, which ensured that the adhesive wet shear strength was increased by 33% to 0.89 MPa. This study provided an idea for the preparation of highly dispersed nanoparticle reinforced adhesives.
