Tailoring of Self-Healable Polydimethylsiloxane Films for Mechanical Energy Harvesting.

Triboelectric nanogenerators (TENGs) have emerged as potential energy sources, as they are capable of harvesting energy from low-frequency mechanical actions such as biological movements, moving parts of machines, mild wind, rain droplets, and others. However, periodic mechanical motion can have a detrimental effect on the triboelectric materials that constitute a TENG device. This study introduces a self-healable triboelectric layer consisting of an Ecoflex-coated self-healable polydimethylsiloxane (SH-PDMS) polymer that can autonomously repair mechanical injury at room temperature and regain its functionality.

Chemically modified polyurethane coating was patterned by application of a laser beam. A set of patterns with variously distant linear peaks and grooves was obtained.

- Polarizers are essential in optoelectronic devices like displays and cameras, but they struggle with significant optical losses when controlling light polarization.
- Organometal halide perovskites (OMHP) offer tunable optical properties and low energy losses, making them ideal for applications in photovoltaics and optoelectronics.
- The study focuses on creating highly aligned methylammonium lead iodide perovskite nanowalls, which enhance light absorption and sensitivity to polarization, paving the way for advanced optoelectronic devices.
