AB  - Poly(dimethylsiloxane) (PDMS)-based microfluidics provide a novel approach to 
      advanced material synthesis. While PDMS has been successfully used in a wide 
      range of industrial applications, due to the weak mechanical property channels 
      generally possess low aspect ratios (AR) and thus produce microparticles with 
      similarly low ARs. By increasing the channel width to nearly 1 cm, AR to 267, and 
      implementing flow lithography, we were able to establish the slit-channel 
      lithography. Not only does this allow us to synthesize sheet materials bearing 
      multiscale features and tunable chemical anisotropy but it also allows us to 
      fabricate functional layered sheet structures in a one-step, high-throughput 
      fashion. We showcased the technique's potential role in various applications, 
      such as the synthesis of planar material with micro- and nanoscale features, 
      surface morphologies, construction of tubular and 3D layered hydrogel tissue 
      scaffolds, and one-step formation of radio frequency identification (RFID) tags. 
      The method introduced offers a novel route to functional sheet material synthesis 
      and sheet system fabrication.
