Flexible EMI shielding fabrics by using conductive polymer

Tanushree V. Tandel & Smita Deogaonkar-Baride

Nowadays, new development in electronics and electrical devices leads to a new type of electronic pollution, which is called electromagnetic interference. It affects the efficiency, life, and safety of the operation of electronic devices. Electromagnetic
interference is the current major issue, and to overcome this issue, the EMI shield is used. For EMI shielding, metal oxide,
magnetic materials, and metals are used, but they have some limitations like flexibility, heaviness and high costs.

Importance of Alkaline Resistance Polyester in Geosynthetic Application

Shyambabu K. Sainik & Prasanta K. Panda
Geosynthetic materials are innovative and versatile synthetic products that play a vital role in various civil engineering and construction projects to reinforce soil and control erosion. These materials are engineered from polymers and designed to exhibit specific properties that enhance their performance in geotechnical, hydraulic, and environmental projects. Unlike traditional construction materials, geosynthetics offer a range of benefits that can significantly improve project efficiency, sustainability, and long-term durability.

Study of structural and optical properties of aluminium-doped ZnO films on polyethylene terephthalate substrate via radio-frequency sputtering

Abhishek Panwar , Nishant Chandel , Sanjay Kumar
Al/ZnO films, which are ZnO doped with aluminium, were created by radio-frequency magnetron sputtering in this instance. Polyethylene terephthalate was used as a substrate to prepare Al/ZnO films. The radio frequency (RF) magnetron sputtering power varied from 120 to 140W. Through the use of ultraviolet (UV), field emission scanning electron microscopy (FE-SEM), and X-ray diffraction (XRD),…….

Effect of Plasma on the Mechanical Strength of Khadi Cotton

Afreen Begum & Padma Shree Vankar
Exposure to plasma does lead to surface erosion of textile material, we were interested in evaluating the effect of plasma treatment on the mechanical strength condition for Khadi cotton fabrics. Although surface erosion roughens and creates a larger contact area, and it is ideally suited for better dye uptake of the cotton fabrics. The surface erosion also led to the change in the content of carboxyl and carbonyl groups of the cotton fibers which was established by XPS studies.
