| Abstract: |
| A novel cellulose composite membrane， HKUST-1@CF loaded with metal-organic frame （MOF， i.e.， HKUST-1）， was prepared by electrospinning pretreatment using dissolving pulp as raw material and trifluoroacetic acid （TFA）/dichloroethane （DCE） as dissolving system. Polyethylene oxide （PEO） and copper acetate （Cu（Ac）2） were pre-added into the dissolving system as thickener and precursor， respectively， to fabricate spinning dope system. The effects of dissolving pulp type， TFA/DCE volume ratio， and PEO and Cu（Ac）2 dosages on the structure and properties of HKUST-1@CF were comprehensively investigated. The results showed that when hardwood dissolving pulp was used as raw material， the volume ratio of TFA/DCE was 6∶4 and the mass ratio of cellulose/PEO/Cu（Ac）2 was 10∶2∶3， cellulose had the best spinning performance. The pre-addition of PEO and Cu（Ac）2 contributed to the HKUST-1 load， up to 16.1%. The as-prepared composite membrane showed excellent oil-water separation with separation efficiency of 98% and good bacterial inhibition performance with inhibition circle of 3.1 mm， showing potential application value in membrane separation and environmental governance. |
