Cellulose derivatives are one of the carbohydrate polymers which received a great interest in the construction of nanostructured materials. Particularly, the ethyl cellulose provides an enormous support to the metal nanoparticles. To the best of our knowledge, this is the first time report for the simple and rapid synthesis of ethyl cellulose (EC) supported platinum nanoparticles (PtNPs) for the determination of non-enzymatic hydrogen peroxide (HO). The PtNPs/EC composite was confirmed by various characterizations such as fourier transform infra-red spectra, energy dispersive X-ray spectra, field emission scanning electron microscope and cyclic voltammetry. Further, the PtNPs/EC composite modified glassy carbon electrode (GCE) was successfully determined the HO with the linear concentration range from 0.05μM to 2.22mM and the lowest detection limit of 0.01μM. Moreover, the PtNPs/EC/GCE sensor electrode manifested an acceptable sensitivity, selectivity and reproducibility. In addition, we have determined the HO in contact lens solution and human blood serum samples.

Structural health monitoring (SHM) systems are critical in ensuring the safety of space exploration, as spacecraft and structures can experience detrimental stresses and strains. By deploying conventional strain gauges, SHM systems can promptly detect and assess localized strain behaviors in structures; however, these strain gauges are limited by low sensitivity (gauge factor, GF ∼ 2). This study introduces an approach to printing strain gauges with high sensitivity, while also considering stretchability and long-term durability.

Ethyl cellulose (EC) is a biocompatible, renewable, and recyclable material with diverse sources, making it an attractive candidate for industrial applications. Electrospinning has gained significant attention for the production of EC fibers. However, conventional electrospinning methods face challenges such as bead formation, low yield, and the absence of porous internal structures, limiting both the functional performance and scalability.

In order to provide long-term anti-corrosion properties of the coatings on the substrate, a microcapsule self-healing coatings system was designed in this paper. Microcapsules were synthesized with ethyl cellulose and octadecyl amine, which were added to epoxy resin to prepare self-healing coatings. The shape of microcapsules was spherical, the average particle size of microcapsules was about 100-120 μm, and the average thickness of microcapsules was 4.
