AbstractProtein material resulting from chemical free steam explosion of wool was mixed in different proportion with polyamide 6 in formic acid. The viscosity of the blend solutions decreases with the increase of the protein amount in the blend. Nanofibres produced by electrospinning of these polymer blends show an increase of the filament diameters with increasing protein amounts, except for the 30/70 v/v polyamide 6/protein blend, where nanofibres with “beads” defects were produced. In blend films produced by casting, polyamide 6 crystallize in the form of large spherulites prevalently in the α crystalline structure, while protein is totally amorphous and tends to segregate in the course of drying at room temperature. Otherwise, in electrospun nanofibres polyamide 6 and protein show a better miscibility as suggested by spectroscopic and thermal analysis and polyamide 6 shows a higher thermal stability. Moisture regain and water solubility of blend cast films and electrospun nanofibres respectively were also determined.

Properties Of Composites

In this paper several properties of new materials based on polymer blends were studied. The properties of composites made of the blends of chitosan and collagen with addition of poly (methyl methacrylate) and hydroxyapatite were investigated. Mechanical properties, thermal analysis, FTIR spectra and SEM images were obtained for different blends of chitosan/collagen in weight ratios 75/25, 50/50, 25/75. Poly (methyl methacrylate) was used in ratios 15, 50 and 85 wt% based on chitosan. The influence of the addition of hydroxyapatite to the polymer blends on their properties was tested. The results showed that the amount of components can influence on the mechanical properties observed for obtained materials.

Shearing Mechanism

One of the major disadvantages of epoxy resins when they are used to impregnate a fabric or when they are used to obtain laminates is their rigidity that leads in loading conditions to the matrix fracture followed by breaking of fabric due to a shearing mechanism in which the two free parts of the matrix fracture acts as a scissor. During the design of a composite material or structure such behavior of the matrix has to be taken into account and the problem could be solved if the rigidity of the matrix is reduced. The present study is about changing the value of this parameter by using an organic polymer solvent and a thermoplastic polymer to modify the basic properties of an epoxy resin. At this time an analysis of thermal properties of polymer blends is done to determine the effect of solvent and thermoplastic polymer presence inside the epoxy matrix.
