“…Therefore, the researchers often process the powder into a thin film or other molded body through the method of material compounding to facilitate the application of COF materials. 34,35 Here, a functional ACF-TpPa-1 composite adsorption material that is expected to treat dye wastewater efficiently is introduced (Figure 1). CF is selected as the matrix of the material, and EDA is used to aminate CF to increase the number of -NH 2 on the surface, TpPa-1 is used as a modifier to improve the adsorption performance.…”

Environmental challenges, especially dye wastewater produced by printing and dyeing industry, pose a serious threat to global public health, and it is an urgent problem to realize harmless treatment of dye wastewater. Here, the combination of covalent organic framework materials (TpPa-1) and biological matrix materials (CF) was explored for the adsorption of dyes for the first time. The functional ACF-TpPa-1 composite adsorption materials were successfully prepared with collagen fiber (CF) made of leather waste as matrix, ethylenediamine (EDA) and covalent organic framework material (TpPa-1) as modified raw materials. It’s structure and properties were characterized by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). The experimental results showed that ACF-TpPa-1 had an adsorption capacity of 257.98 and 449.54 mg/g for acid fuchsia and reactive blue 19, respectively. It also showed excellent adsorption/desorption performance and repeatability after six cycles. As a collagen-based dye adsorbent with pH response, it has potential application prospects in the treatment of dye wastewater.

“…The obtained membrane exhibited compromised selectivity while visibly enhanced permeability compared with the pure polymer membrane due to the declining diffusion resistance that was derived from the incorporated COFs. By virtue of the similar strategy, COFs materials with different morphologies including particles, [52][53][54]61,[150][151][152][153][154][155][156][157][158][159][160][161][162][163] hollow sphere, [164] nanosheets, [57,165,166] and hybrids [155,[167][168][169][170][171][172] were integrated into polymer to prepare COF-based MMMs for various separation applications, such as gas separation, water treatment, and PV.…”

Covalent Organic Framework Membranes for Efficient Chemicals Separation

Membrane-based separation is an emerging technology to separate different components. [1] Owing to not only the functions of separation, concentration, and purification, but also the properties of energy efficiency, environmental friendliness, high efficiency, simplicity, manufacturing scalability, small footprint, and ease of operation and control, this technology has been widely used in chemical industry, environmental protection, medicine, food, and desalination. [2,3] Membrane is regarded as a significant method to solve the far-reaching issues such as water shortages, environmental pollution, and energy crisis.Along with the rapid industrialization and sharp increase in population, the problems of water shortages, environmental pollution, and energy crisis become more and more severe and complex, leading to the higher technology requirement for membrane separation. Although the frequently used traditional polymer membrane featured with low cost, good mechanical strength, excellent flexibility, and ease of processing, the two key parameters of permeability and selectivity that are generally used to evaluate membrane separation performance are interinhibitive because of the well-known trade-off effect. [4] One of the main reasons for the trade-off effect is the wide distribution of pore size in polymeric membranes. Therefore, materials with uniform and well-ordered pores are considered as perfect candidates for fabricating highperformance separation membranes. Keeping this in perspective, many meaningful studies have been conducted for constructing homoporous membranes [5] with traditional polymers as starting materials. The obtained membranes have a pore size ranging from 5 to 50 nm and possess great potential for ultrafiltration (UF). [6] However, in some practical application systems such as gas separation, dyes removal, protein and drug recovery as well as desalination, the kinetic dimensions of components to be separated usually are less than 5 nm. Therefore, it is very important that a homoporous structure with a pore size of less than 5 nm is constructed to be used in membrane separation.Covalent organic frameworks (COFs) [7][8][9][10][11] are an emerging class of organic porous crystalline materials with pores that range from 0.5 to 5 nm, [12,13] which are entirely composed by light elements, such as C, H, O, N, B, and Si and are connected by strong covalent bonds. Owing to the unique nature of their well-ordered and tailorable pore channels, high and permanent porosity, excellent thermostability and chemical stability, and ease of functionalization, COF materials have been demonstrated promising potential in many applications, including separation, [14] catalysis, [15] sensor, [16] optoelectronics, [17] energy conversion, [18] and semiconductors, [19] among others. Particularly, these characteristics of COF materials perfectly meet the requirements for making advanced separation membrane. For example, the uniform aperture, high porosity, and excellent stability are beneficial
