“…After esterification, viscosity decreased. This phenomenon is normal as esterification converts alcohol OH to eater group, decreasing polarity of starch macromolecule chain and interforce with water molecule, enhancing macromolecule chain mobility, decreasing motion resistance 39 . This cognization is normal as ester can normally be used as lubricant with smaller friction coefficient.…”

Esterification is a normal method for starch modification while reaction condition is not clear. Here, pure corn starch and vinyl acetate were chosen for starch esterification. Reaction conditions involving esterifying agent content, pH, reaction time and temperature were explored. Dess‐Martin periodinane (DMP) pretreatment was adopted to accelerate esterification. Main results reveal that a content of 30 wt% vinyl acetate, pH = 9, time as 1 h and temperature as 45°C is an optimized condition for vinyl acetate esterification and DMP oxidization can enhance it. After modification, variations in microstructure, surface morphology and macroscopic properties such as viscosity, transparency, adhesion property were explored by FT‐IR, XRD, SEM, TGA, UV–Vis, viscosity, and slushing experiments. Main results reveal that after esterification carbonyl groups were introduced, lattice plane occurred expansion, surface morphology was destroyed, water absorption capacity, viscosity, and gelatinization temperature decreased while transparency, thermal‐stability and adhesion property increased. DMP treatment enhanced the previous variations. It seems via a middle‐level DMP pretreatment and vinyl acetate esterification starch solution viscosity and gelatinization temperature decreased greatly while transparency and adhesion force increased greatly, possibly having a potential use in textile industry. For instance, using as slurry its manufacture cost can be decreased with decreased energy consumption, economical.

“…4 In order to solve the above problems, considerable attention has been focused on renewable, eco-friendly, and clean resources to replace the petroleum-based resources to prepare adhesives. Consequently, the development of green adhesive technology from renewable resources has attracted more and more attention, such as lignin, 5 starch, 6 cellulose, 7 and plant oil. 8 Lignin is a very complex, amorphous, and aromatic renewable polymer with three-dimensional network structure, which exists widely in plant somatic cell wall as a protection matrix covering cellulose.…”

With the decreasing of petrochemical resources and the increasing severity environmental pollution, the development of environmentally friendly adhesive technology using renewable resources has attracted more and more attention. Inspired by mussels, a novel biomimetic adhesive synthesized using polyaspartamide derivative (PolyAspAm(DOPA/OA)) and alkali lignin (AL). The physical/chemical structure and properties were examined by 1H‐NMR, Fourier‐transform infrared spectroscopy, thermo gravimetric analysis, scanning electron microscopy, water absorption, in vitro cytotoxicity, lap shear tensile, and three‐point bending tests. The adhesive capacity was improved significantly when AL added into PolyAspAm(DOPA/OA). The lap shear tensile for four different substrates (metal and plastic) both increased greatly. The underwater adhesion test possessed good underwater adhesion properties. The results confirmed that hydrogen bonds and chain entanglement were formed between PolyAspAm(DOPA/OA) and AL. It was the introduction of catechol groups and physical–chemical interactions between PolyAspAm(DOPA/OA) and AL improved the adhesion strength and water resistance of the adhesive. Moreover, the corn stover non‐wood boards were prepared by one‐step hot pressing using PolyAspAm(DOPA/OA) with AL adhesives. The three‐point bending of corn stover non‐wood boards increased from 5.00 ± 0.03 to 14.85 ± 20.1 MPa. Overall, this work shows that a nontoxic, environmentally friendly PolyAspAm(DOPA/OA) with AL adhesive has extensive application prospects.

Novel fillers from sago starch and esterified sago starch were employed as natural fillers for rigid polyurethane foams (RPUFs). Sago starch was esterified by maleic anhydride, resulting in the presence of ester groups on the starch structure. Filled RPUFs were prepared with 0.5-7.0 wt% of starch fillers in the polyol component. The influence of filler type and content on the cell morphology and properties of the RPUFs was analyzed. The results revealed that the esterified sago starch showed better compatibility with polyurethane matrix than the sago starch, which in turn impacted the cellular morphology and physico-mechanical properties of the resulting RPUFs. The density and compressive strength of the RPUFs filled with esterified sago starch were higher than those filled with unmodified sago starch, while their water absorption, and volume shrinkage were lower. The findings also suggested that the compressive strength and density of filled RPUFs increased with starch filler content up to the optimal point and then decreased. This was due to the impact of filler content on cell size, with smaller cell size at low filler content leading to increased strength and density, whereas larger cell size and more open cells at higher filler content reducing strength and density. The best properties were obtained with 1.0 wt% of unmodified sago starch and 0.5 wt% of esterified sago starch in the polyol component.
