“…These distinct morphologies gave different mechanical performances with higher modulus and/or toughness in function of the dispersion extent. 30, 31 Lipatov et al [32][33][34] reported that the addition of solid particles into an immiscible polymer blend increases the thermodynamic stability of the mixture and changes the compositions of the separated phases. The authors proposed a simultaneous action of two mechanisms to explain the effect of fillers on the phase behavior: (i) the thermodynamical alterations at the interface because of the selective adsorption of one of both components and (ii) the redistribution of components at the interface and in the bulk that may diminish the phase-separation temperature.…”

Hydrogels are a versatile tool for a multitude of applications in biomedical research and clinical practice. Especially collagen and fibrin hydrogels are distinguished by their excellent biocompatibility, natural capacity for cell adhesion and low immunogenicity. In many ways, collagen and fibrin represent an ideal biomaterial, as they can serve as a scaffold for tissue regeneration and promote the migration of cells, as well as the ingrowth of tissues. On the other hand, pure collagen and fibrin materials are marked by poor mechanical properties and rapid degradation, which limits their use in practice. This paper will review methods of modification of natural collagen and fibrin materials to next-generation materials with enhanced stability. A special focus is placed on biomedical products from fibrin and collagen already on the market. In addition, recent research on the in vivo applications of collagen and fibrin-based materials will be showcased.

“…The introduction of nanoparticles, in particular layered silicates, in polymer blends can promote their morphology refinement, since the nanoclays, confined at the interface between the two polymeric phases, can enhance the interfacial adhesion and promote the morphology modifications from droplet-like to cocontinuous [12][13][14]. Hence, significant properties enhancement for immiscible polymer blends containing nanoparticles can be gained due to the synergism between the reinforcement action of the fillers and the blend microstructure changes [15].…”

The photooxidation behaviour of low-density polyethylene (LDPE)/polyamide (PA) blends, containing polyamide 11 (PA11) or polyamide 6 (PA6), has been investigated in the absence and presence of a small amount of commercial organomodified clay (OMMT). The polymer blends LDPE/PA11 and LDPE/PA6 at 75/25 wt./wt.%, with and without OMMT, have been prepared by a two-step procedure: extrusion and sheet formulation. The formulated complex systems have been subjected to accurate morphological analysis in order to evaluate the effect of the OMMT presence on the refinement of the blend morphology. Furthermore, the produced sheets have been subjected to arterial UVB exposure and the variations of the mechanical properties and chemical structure of all the investigated samples have been monitored as a function of the exposure time. Finally, the rate of the photodegradation of the complex systems has been related to the morphological changes of these systems upon OMMT addition.
