We developed a facile methodology for fabricating a free-standing mixed-matrix membrane (MMM) containing covalently incorporated vinyl-functionalized UiO-66-CH=CH2 particles up to 60 wt% by utilizing thiol-ene photopolymerization. FTIR, TGA, SEM, EDX, and XRD strongly supported the fact that the desired MMM containing well-dispersed UiO-66-CH=CH2 particles was successfully produced by C–S bond formation. The MMM was highly flexible and showed improved mechanical properties compared to the pristine polymeric membrane, indicating that the covalently immobilized UiO-66-CH=CH2 particles were homogeneously distributed in the polymer matrix. Gas permeability across the MMM was significantly enhanced compared with the pristine polymeric membrane as diffusion of the gas molecules was facilitated in the porous space of the MOF.

양이온계 광중합에 적용 가능한 propenyl ether 형태의 단량체들을 mono 및 di-functional alcohol과 allyl bromide의 축합반응으로 합성하였다. 이들 단량체들을 양이온 광개시제와 혼용하여 코 팅조성물을 제조하여 광경화 반응성을 조사하였다. 그 결과 mono propenyl ether 형태인 ((prop-1-en-1-yloxy)methyl)benzene (POMB)는 dipropenyl ether 계인 1,4-bis(prop-1-en-1-yloxy) benzene (BPOB) 비교하여 초기 중합 속도는 10.2로 상대적으로 낮게 나타났으나 1.5mol%의 광개시제 를 포합한 배합물에서는 90초이내에 거의 정량적으로 반응하였다. 또한 긴알킬기를 갖는 술폰산 염계 광개시제들은 단량체들에 빠른 용해 특성을 나타내었고 산성도가 높은 광개시제인 (4-n-decyloxyphenyl)diphenylsulfonium hexafluoroantimonate (DPSA)와 (4-n-decyloxyphenyl) diphenylsulfonium triflate (DPST) 를 사용한 경우 비교적 높은 중합속도와 전환율을 나타내었다.
