传统石油基聚合物膜材料在其服役周期完成后,既难再生、回收又难降解处理,从而造成环境污染压力。生物基聚合物微孔膜有望解决这一问题。在一次性水深度过滤膜、血液净化及污水处理兼碳源缓释膜方面具有应用前景。中科院宁波材料所刘富研究员带领的液体分离与净化团队近年来系统开展了生物基聚合物微孔膜的可控合成制备及应用研究。针对聚乳酸微孔膜的结构控制及制备方面已经制备了梯度结构的微孔膜,及表面肝素化/类肝素化改性微孔膜。如通过多巴 Traditional petroleum-based polymer membrane materials in its service life cycle is completed, it is difficult to regeneration, recycling and refractory treatment, resulting in pressure on environmental pollution. Bio-based polymer microporous membrane is expected to solve this problem. In the one-time water depth filter membrane, blood purification and sewage treatment and carbon source release film has the application prospects. In recent years, the Liquid Separation and Purification Team led by Liu Fu, a researcher at the CAS Ningbo Institute of Materials, has systematically developed and applied controlled synthesis of bio-based polymer microporous membranes. For the structure control and preparation of polylactic acid microporous membrane, a gradient structure microporous membrane and a surface heparinized / heparin-like modified microporous membrane have been prepared. Such as through the Dopa
