Pressure sensors based on nitrogen-doped bamboo-shaped carbon nanotubes (N-BCNT) and black (CB) as nanofillers, polyurethane foam (PU) supporting substrate, silicone rubber (SR) a matrix were prepared. Dip coating was used to coat PU with 0.44 wt% nanofiller, including different mixing ratios of N-BCNT CB (5:5; 6:4; 7:3; 8:2; 9:1). Then, the coated is impregnated in SR fill pores. Due higher aspect ratio N-BCNT, it contributes more improving electrical conductivity composites, while fills...
In this work, three different polyurethane (PU) foams were prepared by mixing commonly used isocyanate and polyol with indices (1.0:0.8, 1.0:1.0, 1.0:1.1). Then, the foam samples coated dip-coating a fixed ratio of nitrogen-doped, bamboo-shaped carbon nanotubes (N-BCNTs) to obtain pressure sensor systems. The effect index on initial resistance, sensitivity, gauge factor (GF), repeatability N-BCNT/PU systems was studied. pore volume crucial in finetuning PU-foam-based sensors ability detect...
In this study, a novel technology is reported to prepare piezoresistive polyurethane-silicone rubber nanocomposite. Polyurethane (PU) foam was loaded with nitrogen-doped bamboo-shaped carbon nanotube (N-BCNT) by using dip-coating, and then, impregnated silicone rubber. PU used as supporting substrate for N-BCNT, while applied fill the pores of improve recoverability, compressive strength, durability. The composite displays good electrical conductivity, short response time, excellent...
Abstract Flexible pressure sensors (FPS) are crucial for emerging applications like wearable electronics, human activity monitoring, and soft robotics. This study reports a scalable cost‐effective approach to fabricate high‐performance piezoresistive FPS based on polyurethane‐silicone rubber (PU‐SR) nanocomposites. The synergistic integration of nitrogen‐doped bamboo‐shaped carbon nanotubes (N‐BCNT) black (CB) nanofillers within the PU‐SR matrix was achieved via novel dip‐coating...
