A hydrophilic bamboo cellulose nanofiltration membrane (IP-NF-BCM) was prepared through interfacial polymerization (IP) of amino-functional piperazine (PIP) and 1,3,5-trimesoyl chloride (TMC) on a cellulose surface. The in situ formation of polyamide into the mesoporous structure of the regenerated cellulose film created a uniform microporous membrane, which can be used for water softening by nanofiltration. The interfacial polymerization reaction conditions were optimized in terms of the performance of resultant nanofiltration membranes. The chemical structure, morphology, and surface charge of the composite membranes were characterized based on thermal gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), atomic force microscopy (AFM), nuclear magnetic resonance (NMR), and Brunauer–Emmett–Teller (BET) nitrogen absorption. The water permeation and salt rejection capability of the bamboo cellulose thin-film-composite nanofiltration membranes were evaluated using 500 ppm salt solutions at 0.5 MPa pressure. Results show that the rejection rate for NaCl reached 40% and water flux reached 15.64 L/(m2·h). The average pore size of the bamboo cellulose thin-film-composite membranes was 1.0 nm.

哌嗪与三甲磺酰氯界面聚合制备纤维素基纳滤膜及其表征
通过氨基官能哌嗪（PIP）和1,3,5-三甲酰氯（TMC）在纤维素表面的界面聚合（IP）制备了亲水性竹纤维素纳米过滤膜（IP-NF-BCM）。将聚酰胺原位形成到再生纤维素膜的中孔结构中可形成均匀的微孔膜，该膜可用于通过纳滤进行水软化。就所得纳米过滤膜的性能而言，优化了界面聚合反应条件。基于热重分析（TGA），傅里叶变换红外光谱（FT-IR），场发射扫描电子显微镜（FE-SEM），X射线衍射（TGA）表征了复合膜的化学结构，形态和表面电荷XRD），原子力显微镜（AFM），核磁共振（NMR）和Brunauer-Emmett-Teller（BET）氮吸收。使用0.5 ppm压力下的500 ppm盐溶液评估了竹纤维素复合薄膜纳米过滤膜的透水和除盐能力。结果表明，NaCl的截留率达到40％，水通量达到15.64 L /（m2 ·h）。竹纤维素复合薄膜的平均孔径为1.0nm。
