“…Developing polymer binary systems is a versatile strategy for obtaining novel biomaterials with improved properties [101,102]. The addition of the second polymer in a binary system not only provides the original characteristics of the additives to the polymer blend, but also generates novel attributes by tuning the structure of the polymer blend, improving processing and lowering production costs [103][104][105]. To fabricate functional materials, such as biomaterials using binary polymer fibres, forming must occur on a technologically viable scale, generating fibres with a large surface area and tuneable porosity [38,106].…”

Binary polymer systems provide significant advantages in the preparation of materials used in biomedical applications. To highlight the importance and need of binary polymer systems in biomedical applications; utilisations of nano-carrier and fibre are discussed in detail in terms of their use as biomaterial, and their potential for further development with focus on dual and sequential drug delivery applications. On the other hand, in fibre technology, creation of binary polymer systems have been investigated using spinning processes such as electrospinning and even more recently innovated pressurised gyration. How these methods can be used to promote the mass production of binary polymer systems with various morphologies and characteristics are elucidated. The effects of different polymer materials, including solvents, mechanical properties, and the rate of degradation of polymers, are discussed. Current polymer blending systems and manufacturing processes are analysed, and technologies for biomaterials are carefully considered with up to date details.

“…Another fundamental factor influencing the development of the phase morphology during melt processing operation dominated by the elongational flow is coalescence; in fact, in the presence of intense interactions among the particles of dispersed phase, due to high concentration or restricted geometries, numerous collisions occur, hence possibly causing coalescence phenomena [159]. For instance, during melt spinning, the shrinking matrix compresses the droplets of dispersed phase, enabling them to migrate form the surface toward the center of the fiber and promoting coalescence events [160,161]. He et al [162] reported the formation of a coalescence region during the melt spinning of immiscible polystyrene/polypropylene blends performed at take-up rates higher than 750 m/min, in which an increase of the diameter of the droplets of polystyrene along the spinning line was observed.…”

Polymer-processing operations with dominating elongational flow have a great relevance, especially in several relevant industrial applications. Film blowing, fiber spinning and foaming are some examples in which the polymer melt is subjected to elongational flow during processing. To gain a thorough knowledge of the material-processing behavior, the evaluation of the rheological properties of the polymers experiencing this kind of flow is fundamental. This paper reviews the main achievements regarding the processing-structure-properties relationships of polymer-based materials processed through different operations with dominating elongational flow. In particular, after a brief discussion on the theoretical features associated with the elongational flow and the differences with other flow regimes, the attention is focused on the rheological properties in elongation of the most industrially relevant polymers. Finally, the evolution of the morphology of homogeneous polymers, as well as of multiphase polymer-based systems, such as blends and micro- and nano-composites, subjected to the elongational flow is discussed, highlighting the potential and the unique characteristics of the processing operations based on elongation flow, as compared to their shear-dominated counterparts.

“…Thermoplastic polymers are environmentally friendly, and it can improve impact strength, damage tolerance, durability, and repair capability. However, the relatively high viscosity (100-10,000 Pa.s) of molten thermoplastics limits the impregnation capability, resulting in poor product quality (Chen et al, 2019;Zoller et al, 2019).…”

Lately, natural fibers have been gaining consideration in development of composites due to its biodegradability, availability and low-cost compared to synthetic fibers. Natural fibers are renewable sources, biodegradable, environmentally friendly and effortless in machinery. In this paper, the manufacturing of production for natural fiber reinforced polymer composite (NFRC) will be reviewed. These including injection molding, resin transfer molding (RTM), pultrusion, sheet molding compound (SMC) and compression molding processing technique. Injection molding and compression molding are mostly used in industry. This is due to the machines give a good finishing surface of the products and low cost.
