Abstract Hydrogel‐based solar interfacial evaporators, featuring various channels such as random, unidirectional, and radial array, are considered effective for seawater desalination owing to their porous structure, lower evaporation enthalpy, controllable water transport capacity. However, each individual array structure has its own strengths limitations, influencing transportation, thermal management, salt rejection. By combining the benefits of configuration into a single evaporator, performance can be maximized. Herein, study develops unique nanofibrous hydrogel‐based evaporator combined radical/vertical structure. This integrated with external internal vertical endows this excellent capability reduced heat loss, resulting in superior high salty resistance. The addition nanofibers hydrogels not only enhances hydrogel's stability but also facilitates transport. Under 1 sun illumination, achieve an impressive rate 4.62 kg m −2 h −1 energy efficiency 149.57%. After 12 20 wt.% NaCl solution, it still maintains average 3.98 minimal accumulation, thereby exhibiting exceptional resistance durability.

Polysaccharides, the most abundant biopolymers in nature, have attracted attention of researchers and clinicians due to its practicality biomedical pharmaceutical sciences. These biomaterials high bioavailability play structural functional roles living organisms. Polysaccharides are classified into several groups based on their origin, including plant polysaccharides marine (like chitosan, hyaluronic acid, dextran, alginates, etc.) with specific applications. possess unique physicochemical (such as surface groups, solubility, stability), mechanical strength tensile), antioxidant activity, biocompatibility, biodegradability, renewability, non-immunogenicity) characteristics which made them excellent platforms for a wide variety Ease extraction different preparation approaches mentioned other potential properties that further improved They drug/bioactive encapsulation capacity sustained/controlled release manner vivo microenvironments.
