A wind turbine blade made of basalt carbon fiber composite variable density material combination, including at least one blade unit assembled along the length direction of the blade, the density gradient increases from the blade tip to the blade root through the gradient distribution of material density and / or the gradient distribution of hollow structure, and adjacent blade units are detachably connected through non-threaded connection structure. The modular design of the blade solves the problem of land transportation of oversized blades, and the non-threaded connection (hand disassembly) improves the efficiency of on-site installation and eliminates the risk of thread loosening. Lightweight blade tip reduces starting torque, facilitates handling and assembly, and improves wind speed and power generation efficiency.

This invention relates to the field of sensing materials technology, specifically disclosing a cellulose-based conductive hydrogel material for ascorbic acid detection, its preparation method, and its applications. This hydrogel uses TEMPO oxidized cellulose nanofibers (TOCNF) as a biocompatible matrix. By introducing Cu-BTC / CNT composite nanoparticles, a three-dimensional conductive network with both high electrochemical activity and structural stability is constructed. While retaining the biocompatibility and flexibility of cellulose, it exhibits particularly high sensitivity and selectivity in detecting small biomolecules such as ascorbic acid, with short response time and good stability. This method achieves synergistic optimization of the composite material's structural uniformity and functionality without relying on complex molding processes. Experimental results show that the conductive hydrogel prepared by this invention possesses good mechanical properties and biocompatibility, exhibiting high sensitivity and stability in biosensing fields such as ascorbic acid detection, providing a novel high-performance material basis for flexible biosensors.
