AB  - Inspired by iridescent color in natural creations, cellulose nanocrystal (CNC) 
      photonic crystals artificially created by nanotechnology have great application 
      prospects due to their potential to control light propagation in the linear and 
      nonlinear regimes. One of the most important development directions of photonic 
      crystals is the diversification of colors, usually by adjusting the pitch. 
      However, few researchers notice the effect of polymer molecular weight and 
      content on pitch regulation and the interaction between polymer and CNC liquid 
      crystals. Polyethylene glycol (PEG) were used as polymers to regulate the pitch 
      of CNC photonic crystals and investigate the changes in microstructure, crystal 
      structure, thermal properties, and liquid crystal texture of the composites by 
      changing the PEG content and molecular weight. Different photonic crystal 
      construction systems show that when the molecular weight of PEG is 0.4 k, it can 
      be filled between CNCs to regulate the pitch of photonic crystals, while when the 
      molecular weight of PEG is 20 k, it cannot always be filled between CNCs in 
      evaporation-induced self-assembly (EISA) process due to the depletion 
      interaction, which cannot effectively regulate the pitch. This study reveals the 
      relationship between PEG and CNC liquid crystals, which supports the development 
      of photonic crystals and the pitch regulation.
