Summary: This study presents the design of a polymer-film-based gas detection sensor using different types of polyaniline as active layers. The resistive sensors with PANI layers have the advantages of easy preparation and low production cost. The polymer films exhibit high sensitivity to gas concentrations at room temperature. The developed sensor works based on the principle of electrical resistance shifting with gas concentration. Three different polymerization solutions are used to synthesize the PANI active layers, and the PANI layers polymerized in acetic acid solutions show good sensitivity towards ammonia.

Summary: The doped polyaniline mixed with divinylbenzene as a crosslinking thermoset polymer has demonstrated to be an effective structural EMI shielding material, achieving maximum SE values at X-band frequencies with a 1 mm thickness. The primary shielding mechanism of this material is absorption due to its high conductivity, with dielectric constant and permeability estimated to understand the shielding mechanisms. Additionally, a conductive layer based on PANI has been successfully applied to fiber-reinforced composites for self-EMI shielding applications, achieving high SE values for both GFRP and CFRP composites with a 1 mm thickness.

Summary: Composites are materials with different chemical and physical properties made from two or more constituent materials. The filament winding method is an efficient and automated method used to create these materials. This study conducted a stress analysis on the mandrel shaft to determine stress, deflection, and the safety factor value of the design. The highest von Mises stress value was 217.41 MPa with a force loading of 200 N, resulting in a safety factor value of 2.37. Additionally, a prototype of a filament winding machine was created using a 3D printing machine at a reduced size ratio of 1:2.

Summary: The review article discussed how modifying and improving the electrical conductivity of FRP laminates can be used for non-structural applications such as lightning strike protection, EMI shielding, and strain/damage sensing. Different techniques like metal tufting/stitching, conductive resin, coating, and interleaves were discussed for these applications. Metal-tufting and PANI-based conductive resin were found to be effective in resisting lightning damage and performing well in strain sensing and EMI shielding.
