“…Among them are protein-based biocomposites consisting of proteins or protein blends and additives or fillers that are incorporated into the protein (blend) matrix. Depending on the particle size of the incorporated additives, bionanocomposites, biomicrocomposites and biomacrocomposites can be distinguished [33,34,35]. Various embedded organic and inorganic fillers in the form of loose or coherent particles or fibers contribute to the enhancement of physical properties and to the reduction of costs of protein-based biocomposites [35,36].…”

Abstract:The improvement of pharmaceutical dosage forms, such as tablets, towards drug delivery control and cost efficiency is of great importance in formulation technologies. Here, three examples: in situ coating, freeze casting and protein-based biocomposites are presented that address the above mentioned issues and contribute to further developments in formulation technologies. The in situ coating increases the economic efficiency by saving process steps in comparison to a conventional tableting process and provides a crystalline coating for a tailorable drug delivery rate. The freeze casting allows the control over the surface area of a drug delivery system (DDS) by providing different numbers and sizes of pores, which in conjunction with adequate additives offer an efficient instrument for drug delivery control, especially by accelerating the dissolution effect. Protein-based biocomposites are attractive materials for biomedical and pharmaceutical applications that can be applied as a polymeric DDS. They inherently combine degradability in vivo and in vitro, show a good biocompatibility, offer sites of adhesion for cells and may additionally be used to release embedded bioactive molecules. Here, a new approach regarding the incorporation of crystalline active pharmaceutical ingredients (API) into a protein matrix in one process step is presented. All three presented techniques mark decisive progress towards tailor-made drug delivery systems with respect to function, economic efficiency and the generation of additional values.

“…There is a need in developing eco-friendly composites with high performance for complying with circular economy targets in the automotive, construction and packaging industries, and their manufacturing cost should be reduced [1][2][3]. To respond to these demands, in the last couple of decades, biocomposites based on thermoplastics with natural reinforcements and with 90 wt.% biodegradable content have become promising materials.…”

In this study, physical and electrostatic interactions existing between poly(lactic acid) (PLA) and poly(ethylene terephthalate) (PET) fiber were proved as a promising strategy for preparing novel lightweight PLA/PET fiber composites, without the need of adding compatibilizer or carrying out chemical/physical treatments to the fiber. The impact resistance of the PLA/PET fiber composites increased notably by adding up to 1.5 phr PET fibers thanks to the better dispersion of PET fibers and good polymer-fiber adhesion caused by the creation of hydrogen bonds between the surface hydroxyl and carbonyl groups on both polymers. However, the composites with 2-3 phr PET fibers were brittle due to PET fibers aggregation. The glass transition temperature of PLA increased moderately due to the good matrix/filler interfacial adhesion via hydrogen bond interactions, and its crystallinity showed a trivial variation contrary to the crystallites size, this decreased noticeably because of the fibers inhibiting effect. Finally, an increased thermal stability of the PLA/PET fiber composites was demonstrated.
