摘要:
针对PDMS膜的传统制备过程中使用大量有机溶剂，对环境造成严重的污染。采用含一定表面活性剂的水作为溶剂进行PDMS膜的绿色合成，同时掺杂一定量的氧化石墨烯（GO）以提高膜的选择性和稳定性。将制备的GO/PDMS杂化膜应用于甲醇（MeOH）/碳酸二甲酯（DMC）的渗透汽化分离，与传统PDMS膜相比，通量提高了4倍，分离因子提高了2倍，并且随着进料温度的提高，该复合膜的分离因子基本保持不变，证明了其优异的稳定性。
Abstract:
The use of organic solvents in synthesis of traditional polydimethylsiloxane (PDMS) membranes causes severe environmental pollution. Here, water with surfactant as a green solvent for the synthesis of PDMS was proposed to use, and graphene oxide (GO) was introduced into the PDMS solution in order to improve the selectivity and stability of the membrane. The prepared GO/PDMS hybrid membranes were applied to pervaporation separation of MeOH/DMC. Experimental results showed that the flux and separation factor of the resultant GO/PDMS hybrid membranes increased 4 and 2 times respectively, compared with traditional PDMS membranes. Moreover, the separation factor of the membrane could remain constant as the feed temperature increased, demonstrating its superior stability.
