“…PCL/PLA has been noted as one of the most investigated blends among biodegradable polymer composites, as they have shown improved mechanical and thermal properties of PCL. Various research groups have been particularly interested in fabrication methods [ 123 ], overall characterization [ 124 ], as well as biodegradation [ 125 ]. Nowadays, many studies are oriented toward the electrospinning of PCL/PLA blends [ 126 ].…”

This article provides a thorough overview of the available resorbable biomaterials appropriate for producing replacements for damaged tissues. In addition, their various properties and application possibilities are discussed as well. Biomaterials are fundamental components in tissue engineering (TE) of scaffolds and play a critical role. They need to exhibit biocompatibility, bioactivity, biodegradability, and non-toxicity, to ensure their ability to function effectively with an appropriate host response. With ongoing research and advancements in biomaterials for medical implants, the objective of this review is to explore recently developed implantable scaffold materials for various tissues. The categorization of biomaterials in this paper includes fossil-based materials (e.g., PCL, PVA, PU, PEG, and PPF), natural or bio-based materials (e.g., HA, PLA, PHB, PHBV, chitosan, fibrin, collagen, starch, and hydrogels), and hybrid biomaterials (e.g., PCL/PLA, PCL/PEG, PLA/PEG, PLA/PHB PCL/collagen, PCL/chitosan, PCL/starch, and PLA/bioceramics). The application of these biomaterials in both hard and soft TE is considered, with a particular focus on their physicochemical, mechanical, and biological properties. Furthermore, the interactions between scaffolds and the host immune system in the context of scaffold-driven tissue regeneration are discussed. Additionally, the article briefly mentions the concept of in situ TE, which leverages the self-renewal capacities of affected tissues and highlights the crucial role played by biopolymer-based scaffolds in this strategy.

“…The paper will present the formation processes of nonwovens made from continuous filament web: spun-bonded and meltblown technologies. These technologies are good methods of processing thermoplastic biodegradable biopolymers such as polylactide, poly(hydroxyalkanoates), polycaprolactone and polybutylene succinate [34][35][36][37][38][39][40]. Spunbond and meltblown nonwoven webs technology uses the collection of continuous filaments produced by melt extrusion processes.…”

Biopolymer composites have received increasing attention for their beneficial properties such as being biodegradable and having less influence to the environment. Biodegradability of materials has become a desired feature due to the growing problems connected with waste management. The aim of the paper is to emphasize the importance of biodegradable textile materials, especially nonwoven materials with an anti-pathogenic layer. The article refers to the definitions of biodegradation, degradation and composting processes, as well as presenting methods of testing biodegradability depending on the type of material. The study gives examples of biodegradation of textiles and presents examples of qualitative and quantitative methods used for testing antimicrobial activity of biodegradable nonwovens with an anti-pathogenic layer.

“…Nevertheless, due to the nondegradable nature of these materials, the disposal of fiber membranes after oil–water separation introduces other environmental pollution challenges. Biobased biodegradable materials, predominantly poly(lactic acid) (PLA), synthesized from biomass raw materials, contribute to reducing dependency on fossil resources and exhibit excellent processability, rendering them an exemplary choice for developing better separation materials. , The main strategy for modifying PLA membranes has been adding inorganic nanofillers to impart hydrophilic and hydrophobic properties. For example, Mo et al prepared a series of hydrophobic PLA/multiwalled carbon nanotube composite fibrous membranes by electrostatic spinning with high oil absorption capacity .…”

As the global economy continues to expand, the issue of oily wastewater pollution has garnered significant attention. Consequently, this paper reports a poly(lactic acid)-based coblended fiber membrane for oil− water separation. The synthesis of a polyurethane−poly(tetrahydrofuran)− polyurethane (PU−PTHF−PU) polymer at 25 °C and its incorporation at 20 wt % into fibrous membranes resulted in a water contact angle of 138°. The coblended fibrous membranes exhibited a tensile strength of 8.05 MPa and an elongation at break of 46.53%, simultaneously improving the rigidity and toughness of the fiber membrane, endowing the poly(L-lactic acid) (PLLA) fibrous membranes with good hydrophobicity and mechanical properties. Featuring a maximum permeate flux of 3898 L•m −2 •h −1 , an oil recovery efficiency of 99.4%, and outstanding stability and durability, the PU−PTHF− PU/PCL/PLLA [PCL = poly(ε-caprolactone)] fibrous membrane represents an ideal solution as an all-biobased biodegradable membrane for oil−water separation.
