“…The polydispersity is below 0.2, which means it has a good dispersion effect in water. Furthermore, after centrifugation at 3000 rpm for 30 min no phase separation or precipitation occurred in the samples, which means the storage life could be more than 6 months 29 …”

In recent years, structural colors derived from photonic crystals (PCs) with a periodically ordered nanostructure are gorgeous and iridescent, but once their structure is destroyed, they will fade. In this work, the feasibility of the application of bio‐based waterborne polyurethanes (WPU) in structural color films was explored. The structural stability of PCs is enhanced bio‐based WPU as a kind of green product, which can replace solvent polyurethane one. A tung oil polyol (TOP) is fabricated by one‐step method with simple purification process and used to prepare waterborne polyurethane dispersions (WPUD). More introduction of TOP into the WPUD may help improve tensile strength and hydrophobic capability. It shows excellent mechanical properties with 16.8 MPa in tensile strength and water contact angle 109.5°. The SEM images confirmed that bio‐based WPU is more conducive to the self‐assembly of silica particles than traditional WPU.

“…In addition, polyphenolic (e.g., tannic acid, TA) has been widely applied as antioxidants and antimicrobials, and it can combine with proteins, polysaccharides, and alkaloids to form complexes . Up to now, quaternary ammonium salts have been utilized as biocidal agents because of their antibacterial function. − Thus, a method of enhancing antibacterial activity by introducing quaternary ammonium salts into filtration materials can be feasible.…”

Filters play a crucial role in smoke filtration. However, conventional cigarette filters lack degradability or high filtration capacity. Developing cigarette filters with low cost, degradability, and desirable filtration efficiency is an urgent requirement in the cigarette market. In this study, biobased composite aerogels with hierarchically porous structure for cigarette smoke are fabricated. The prepared aerogels consist of naturally biocompatible materials; the microfibrillated cellulose and poly(vinyl alcohol) endow the composite aerogels with mechanical robustness and flexibility. In addition, tannic acid not only has the effect of trapping toxic chemicals in smoke but also performs an antibacterial function in collaboration with the fabricated TTA-Alg polyelectrolyte. It is believed that the hierarchically porous structure of the biobased aerogels induced by the ice template method facilitates the adequate flow of the smoke in aerogels, resulting in high purification efficiency and a relatively constant pressure drop during the smoke filtration process, which is conducive for smoke purification. The prepared aerogel could efficiently capture toxic chemicals in smoke, including filtering 96.58% of oil smoke, 88.64% of total nonmethane hydrocarbons, and 94.79% of particulate matter, exhibiting higher removal efficiency than commercial cigarette filters. In brief, the designed biobased aerogels possess low cost, environmental friendliness, compressibility, and desirable smoke filtration efficiency, showing a promising application prospect for smoke filtration.
