“…The Hildebrand solubility parameters for methanol, ethanol, isopropanol, and 1-butanol are 29.6, 26.2, 23.6, and 23.3 MPa 0.5 , respectively. ,, 1-Butanol exhibits relatively closer compatibility with PDMS (14.9 MPa 0.5 ), leading to a stronger affinity for PDMS . Second, the molecular dynamics radius of methanol, ethanol, isopropanol, and 1-butanol are 0.195, 0.225, 0.235, and 0.25 nm, respectively. ,,− The molecular kinetic radius gradually approaches the r 3 of ME-PDMS. Once bulkier molecules diffuse through the network cavity, the water endures a greater transport resistance coupled with the high hydrophobicity of the ME-PDMS membrane itself, leading to a decrease in water flux and an increase in alcohol flux.…”

“…However, the microorganisms in the fermentation broth are often subject to end-product inhibition due to solvent toxicity . The combination of fermentation and separation technologies is proposed, which aims to optimize solvent production while reducing the associated costs. , Compared with conventional separation techniques, e.g., distillation, pervaporation (PV) offers competitive advantages in the separation of azeotropic mixtures, thermosensitive compounds, and organic–organic mixtures, while PV outperforms distillation in selectivity and energy efficiency . This makes PV a very attractive separation technology …”

The polydimethylsiloxane (PDMS) membrane can be considered the benchmark of alcohol-selective membranes, and its preparation method by photopolymerization shows a great potential on the industrial scale. However, a single photopolymerization system by a free radical or cation is still a challenge to simultaneously have a high reaction speed and oxygen insensitivity. In this work, we proposed a free radical/cationic hybrid membrane-forming system toward PDMS. Both methacrylate groups and epoxy groups were introduced into the PDMS chain by the covalent bonding of 3-methacryloxypropylmethyldimethoxysilane and 3-glycidyloxypropyl(dimethoxy)methylsilane with PDMS. This hybrid system can be quickly cured by a free radical reaction which weakens the oxygen inhibition by a cationic reaction. Furthermore, the transport structure of membranes is effectively controlled by the difference in the reactivity between methacrylate and epoxy groups, where the formed molecular weight and viscosity of the prepolymer are changed from 62,860 to 108,198 g mol −1 and 1.53 to 2.26 Pa s, respectively, and the free volume of membranes is tuned from 5.567 to 6.253%. By optimization, the pervaporation performance of the membrane includes a 1-butanol separation factor of 37.9 and a total flux of 1179 g m −2 h −1 as evaluating 1.5 wt % 1-butanol/water solutions at 55 °C, which has a high superiority coupled with the fast reaction speed and oxygen insensitivity.

“…1 Non-edible and abundant lignocellulosic biomass materials are considered among the most promising feedstocks for the production of chemicals, fuels, and materials. 2 Biomass mainly consists of 40–60% cellulose, 20–40% hemicellulose, and 10–25% lignin along with minor extractives and minerals. 3 Therefore, the valorization of the three polymers into chemicals is critical for the efficient utilization of biomass and has recently received significant attention.…”

“…8 However, the PDMS homogeneous membrane has the problems of low permeation flux and low separation factor. 9 Recently, the mixed matrix membranes (MMMs) prepared by mixed dispersion or in situ synthesis of hydrophobic nanoparticles (such as zeolite, 10,11 silica, 12,13 carbon molecular sieve (CMS), 14 metal organic framework (MOFs), 15 calixarene, 16 etc.) in PDMS matrix have been proven to be an effective method to improve the separation performance of PDMS membrane.…”
