“…Another test of strength characteristics of products is bending which allows to determine the strength, modulus of elasticity, conventional yield strength, and bending deformation. It represents the highest stress that occurs in the material at the moment of damage [ 42 , 43 , 44 ].…”

In this paper flammability tests and detailed investigations of lignin-containing polymer composites’ properties are presented. Composites were obtained using bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA.GDA), ethylene glycol dimethacrylate (EGDMA), and kraft lignin (lignin alkali, L) during UV curing. In order to evaluate the influence of lignin modification and the addition of flame retardant compounds on the thermal resistance of the obtained biocomposites, flammability tests have been conducted. After the modification with phosphoric acid (V) lignin, as well as diethyl vinylphosphonate, were used as flame retardant additives. The changes in the chemical structures (ATR-FTIR), as well as the influence of the different additives on the hardness, thermal (TG) and mechanical properties were discussed in detail. The samples after the flammability test were also studied to assess their thermal destruction.

The method of obtaining nanocomposites based on polyamide-6 and montmorillonite intercalated by polyvinylpyrrolidone by precipitation from a solution in formic acid was developed in the work. The structure and physical interaction between the components of nanocomposites were studied by the methods of XRD, IR spectroscopic, and microscopic analyzes. The presence of polyvinylpyrrolidone in the structure of nanocomposites obtained from the solution was confirmed by IR spectroscopic analysis. Using SEM images, it was established that exfoliated montmorillonite particles with sizes from 100 to 200 nm are present in the structure of nanocomposites.

“…This contributes in many cases to the improvement of the material properties such as modulus of elasticity, strength, thermal stability, fire resistance and barrier characteristics [4,16]. Therefore, nanocomposites are an attractive alternative for use in the packaging, medical, automotive, engineering, and other engineering fields [5,15].…”

This work deals with the development of a method for obtaining polyamide and montmorillonite based nanocomposite, which was modified with polyvinylpyrrolidone by mixing in a formic acid solution. The structure and thermophysical properties of the obtained nanocomposites were investigated by means of the X-ray, differentialthermal, thermogravimetric and IR spectroscopic analyses. It was found that nanomodified polycaproamide has a higher crystallinity and higher thermal stability than the original PA-6, and is characterized by considerably higher melt fluidity. The presence of polyvinylpyrrolidone and exfoliated montmorillonite in the nanocomposite structure was confirmed experimentally.
