Polyurethane (PU) is a well-known synthetic polymer consisting of isocyanates, polyols, and chain extenders. The incorporation of fillers into the PU polymeric matrix, including inorganic nanomaterials, synthetic polymers, natural components, quaternary ammonium salts, and commercial drugs, bestows the endproducts with unique and improved physicochemical properties. Fillers can be used to tailor the molecular orientation, crystallinity, cross-linking, and functional chemical groups of PU-based composites. The bactericidal ability of PU composites highly depends on their surface composition, morphology, charge, and stability. Recent advancements highlight the potential of PU composites in combating bacterial infections. In this review, the cutting-edge of inorganic and organicbased PU composites for antibacterial applications is addressed. Notably, selective examples of scientific reports' key findings and their crucial information on PU composites are discussed. Furthermore, the positive impact of PU composites on the future prospects of this field is explored. This review comprehensively deliberates the values of PU composites towards practical applications in the biomedical field of antibacterial activity. This review can help researchers to gain widespread knowledge and a better understanding of PU composites for antibacterial applications.

“…The amount of fabric softeners is increasing due to their capability of reducing fabric roughness and fiber entanglement. − Polydimethylsiloxane (PDMS) had become the most widely used finishing agent because of its unique Si–O helical molecular structure, , which can wind on the fabric surface, making it easy to form a soft film. − Unfortunately, contrary to the Si–O structure, the H atoms on the two methyl groups connected to the Si atoms are staggered due to the atomic repulsion force. − Therefore, the O atoms cannot form hydrogen bonds with the H atoms of water molecules, resulting in strong hydrophobicity, thus leaving humans feeling hot and sticky. Therefore, personal comfort is difficult to satisfy. − …”

The wettability, breathability, and softness of fabrics are difficult to effect synergistically, so they cannot meet the requirements of personal comfort. Here, inspired by some amazing superhydrophilic structures in nature, a synergistic strategy is reported to create a novel Bola quaternary ammonium polyether polysiloxane (BQPEPS) with a water transport channel and softness performance with a unique inverted U shape, overcoming previous limitations. The results showed that the friction coefficient, bending rigidity, and softness were 0.153, 39.75 mN m, and 553 mN, respectively, which are better than those of commercially available products of two other structures. After 40 cycles of washing, the smoothness, stiffness, and softness of the BQPEPS-treated fabrics remained at 88%, 67.7%, and 63.5%, respectively. Moreover, the total wetting time of the BQPEPS-treated fabrics was less than 1 s, and the water vapor transmission was 792 g m −1 in 24 h. Overall, the successful synthesis of Bola polysiloxane should provide personal comfort and thereby exhibit great potential in practical applications.

“…By adding GO, not just can tensile strength be improved, but also antibacterial activity can be expected as a secondary effect. 19 –23 This effect is ascribed to the GO oxygen functional groups, such as hydroxyl, epoxy, carboxyl, and carbonyl groups, which generate reactive oxygen species. 19,20,24,25 Wan and Chen 26 fabricated waterborne polyurethane (WPU)-GO composite dispersions that enhanced the tensile strength and elongation at break of the composite.…”

Nanotechnology has made biocompatible nanofibers grow in the healthcare industry. Herein, a cellulose acetate (CA) electrospun membrane was characterized by nanofibers of 438 (nm) in diameter between virus and bacteria, pore areas of 36.3%, and a pore size of 395 ± 263 (nm). This structure led to excellent air-water transfer through pore connectivity, contributing to sufficient wettability, air permeability, and water vapor transmission rate (WVTR). The air permeability of pristine CA membranes became predictable through multiple linear regression, based on the correlation to thickness, bulk density (Pearson’s coefficients: 0.754, −0.538). Nonetheless, the tensile strength of the pristine CA needed to be reinforced by spray coating with waterborne polyurethane (WPU) and graphene oxide (GO). The WPU/GO 6:1 (v/v) ratio was optimal due to the increase in ultimate tensile stress to 132.96% due to a synergy of GO’s covalent bonds with WPU’s hard segments and elongation at break to 113.40% from WPU polyols. The WPU/GO 6:1 coated CA membrane possessed still comparable air permeability (36.53 l/m2/s), and WVTR (5736 g/m2/day). Its rapid wetting transition from the Cassie-Baxter’s to Wenzel’s state was attributed to GO’s hydrophilic functional groups. These achievements in reinforcement of tensile strength and wettability would pave the way for filtration, and wound dressing.
