“…17 Hydroclusters can be formed during the transition from an ordered to mobile state, for which the particles aggregate together momentarily and form an incompressible and jammed network. 15,18 Because of the high concentration, Colin 19 elucidated that for a concentrated suspension the rheological properties vary independently of the storage conditions or cell orientation. The equilibrium of the particleparticle Hamaker attractions prevents the collisions between cornstarch particles, alleviating amylopectin erosion for starch dissolution, which is beneficial for the battery electrolyte.…”

“…Therefore, maximizing the use of corn starch holds profound significance in increasing the added value of corn. Moreover, corn starch is an abundant, sustainable, renewable resource with biodegradable potential 22,23 . Additionally, natural corn starch contains a substantial amount of hydroxyl groups, and the hydrogen bonding between these groups leads to the formation of a starch microcrystalline structure, resulting in a higher melting temperature than the decomposition temperature 24,25 .…”

Starch is an environmentally friendly, renewable, green resource and an ideal alternative to polymers from petroleum resources. The preparation of high‐performance poly (butylene adipate‐co‐terephthalate) (PBAT)/corn starch composite materials is of significant importance for saving production costs and expanding the application fields of PBAT plastics. This study employed novel processing techniques such as melt blending and injection molding to fabricate PBAT/corn starch composite materials with polyurethane prepolymer (PCLPU) as a compatibilizer. The impact of varying polyurethane prepolymer concentrations on the composite material's structure, mechanical properties, morphology, thermal behavior, and water absorption was scrutinized. Mechanical performance testing showed that compared to the composite material without PCLPU (P90CS10), adding 5% PCLPU can increase the material's elongation at break from 350.2% to 359.0% and the tensile strength from 12.9 to 19.8 MPa. Scanning electron microscopy, thermogravimetric analysis, and water absorption results indicate that the composite material with the addition of the PCLPU compatibilizer has better compatibility, thermal stability, and water resistance than P90CS10. Additionally, the prepared composite material could be successfully blown into a thin film, further enriching the application of the composite material.Highlights A special interface structure was prepared to increase the compatibility of the poly (butylene adipate‐co‐terephthalate)/corn starch composite. Both the strength and the flexibility of the composite were successfully improved. The processing method through which modification was conducted in the melt was convenient, green, and effective. The prepared composite material has potential application value, and the processing method of the composite material is easy to transfer to industrial production.

Recently naturally driven fabrics are gaining more attention to develop impact-resistive fabrics due to their cost-effectiveness and environment-friendly nature. The effectiveness of jute fabrics becomes more prominent when used with shear thickening fluids (STFs). The present study is focused on the assessment of inter-yarn frictional behavior of jute fabrics impregnated with natural corn flour particles-based STFs. The varying amount of corn flour particles of 10 and 13 µm were blended with deionized water, glycerol, and polyethylene glycol (PEG-400) to synthesize STFs. To the best of our knowledge, first time the stability and rheological performance of corn flour particles-based STFs under varying shear rates in different dispersion mediums have been investigated. The peak viscosity of STF consisting 50% particles (10 µm) in glycerol was found significantly higher compared to the STF consisting same size and concentration of particles with deionized water. The yarn pull-out test was conducted to evaluate the materials’ inter-yarn frictional resistance behavior. The maximum pulling force was observed for jute fabric impregnated with glycerol-based STF. Thus, the developed STFs can be vital for developing better impact-resistive fabrics.
