This was achieved by incorporating lignin-hybrid hollow silica spheres (LHHSs) into a WPU coating applied to sea-island microfibre synthetic leather. The hollow structure of the LHHSs enhances breathability and moisture transport, while lignin hybridisation provides UV absorption and antibacterial performance.
