In article 1702139, Xia Yin, Bin Ding, and co-workers create a free-standing nanofiber/nets air filter assembled with two-dimensional nanonets (≈20 nm) and bonded nanofibers by combining an electrospinning/netting technique and peel off process from designed substrates. Due to small pore size, high porosity, and free-standing capacity, the ultrathin filter can achieve a removal efficiency of >99.00%, light transmittance of ≈70% for PM1 filtration, and >99.970% removal for PM0.3 filtration.
