The crystalline cellulose has captured much attention as reinforcement material in rubber composites, but no successful cases have been found till now. Here, a facile approach of cellulose utilization was proposed by in‐situ regenerating cellulose in dry rubber matrix. Cellulose was dissolved in ionic liquid (IL), and then directly mixed with dry rubber, silica, and other ingredients. Taking advantages of the strong interaction between IL and silica, the dissolution equilibrium of cellulose/IL was destroyed and resulted in the regeneration of cellulose crystals in rubber matrix. The regenerated cellulose appeared at dry blending stage, and showed an ideal rod‐like shape (10–100 nm in diameter and 200–500 nm in length). While it grew in size at curing stage, and finally reached 100–200 nm in diameter and 1–2 μm in length. The regenerated cellulose exhibited pronounced reinforcement efficiency. This methodology has no any waste liquid discharged, and has a promising use in the preparation of cellulose/rubber composites.Highlights Nanosized rod‐like cellulose was regenerated in dry rubber, instead of latex. Regeneration of cellulose was due to interaction between ionic liquid and silica. The in situ regenerated cellulose dispersed well in cured rubber compounds. The regenerated cellulose exhibited a good reinforcement efficiency in rubber. The whole machining process had no any waste liquid discharged.

“…It is used as an adhesive for porous materials such as paper, cardboard, textiles and ceramics. [1][2][3][4] In principle, PVAC would be an excellent candidate to replace synthetic polymers, but the performance of PVAC is still insufficient to meet the requirements of high temperature resistance, mildew resistance and moisture resistance. However, for the requirements of high temperature resistance, mildew resistance and moisture resistance, the performance of PVAC is still insufficient.…”

Poly (vinyl acetate) (PVAC) based on Algerian clay maghnite was synthesized by an emulsion polymerization process in the present study. The prepared nanocomposites were analyzed by means of FTIR, UV‐visible, XRD, AFM, SEM, TGA and optical microscopy. The results obtained showed a semi‐crystalline structure of the composite system revealed by the XRD scheme. The addition of maghnite to the fillers up to 5 wt % has been shown to reduce the optical band gap energy, while the refractive index is greatly increased. The presence of maghnite in PVAC leads to an increase in surface roughness as measured by AFM analysis. The thermal stability of PVAC was significantly improved by the presence of maghnite in the polymer matrix. The mechanical test results indicate that the tensile strength of the polymer composites was improved by the increase in the concentration of clay platelets. The electrical property data show that as the frequency increases, the dielectric constant decreases and the electrical conductivity increases. The loading content of composites also influences their electrical and mechanical properties. This widens the range of applications for these materials in flexible electronics and in conductive coatings.

“…Especially for athletes during exercise, soft insoles with shock absorption can effectively protect their feet. Insoles can be classified as foam insoles [ 4 ], rubber insoles [ 5 ], and ethylene–vinyl acetate copolymer (EVA) insoles [ 6 ], and foam insoles are widely favored for their good shock absorption, breathability, and anti-slip properties [ 7 ]. The main raw materials for preparing traditional foam insoles come from petroleum derivatives, such as polyurethane (PU) insoles, polyvinyl chloride (PVC) insoles, and EVA insoles.…”

The exploitation of bio-based foams implies an increase in the use of renewable biological resources to reduce the rapid consumption of petroleum-derived resources. Both tannins and furfuryl alcohol are derived from forestry resources and are, therefore, considered attractive precursors for the preparation of tannin–furanic foams. In addition, toughening modification of tannin–furanic foams using polyvinyl alcohol (PVOH) results in a more flexible network-like structure, which imparts excellent flexibility to the foams, whose relative properties are even close to those of polyurethane foams, which are the most used for fabrication of insoles for athletes. In addition, the addition of PVOH does not affect the thermal insulation properties of the foams by testing the thermal conductivity, resilience, and elongation at break, while reducing the brittleness of the samples and improving the mechanical properties. Also, the observation of the morphology of the foam shows that the compatibility between PVOH and tannin–furanic resin is good, and the cured foam does not show fragmentation and collapse, while the bubble pore structure is uniform. The developed flexible foam derived from biomass resources endows the foam with good thermal insulation properties and high mechanical properties, and the samples exhibit suitable physical parameters to be used as flexible insoles for athletes.
