AbstractA novel strategy was proposed to fabricate alkali-resistant PVDF membrane via sodium lauryl sulfate (SDS) attached to the surface of membrane and immobilized by UV-curable polyester acrylate and tri(propylene glycol) diacrylate (TPGDA). The attached anionic surfactant, SDS, on the membrane surface can resist the alkali corrosion by NaOH, and the curing of the resin can immobilize the SDS on the membrane firmly. Due to the unique alkali resistance of SDS and resin formed, the UV-curable resin-modified PVDF membrane showed greatly enhanced alkali-resistant ability. Characterization of SEM and FTIR showed that polyester acrylate and TPGDA were cured successfully under the action of 1-hydroxycyclohexyl phenyl ketone (184) and ultraviolet light. Whiteness, differential scanning calorimeter and X-ray photoelectron spectrometer characterization showed that the modified PVDF membrane had a lower degree of dehydrofluorination than the pristine PVDF membrane after alkali treatment. Results of the detailed alkali-resistant analysis indicated that the F/C ratio of the UV-curable resin-modified PVDF membrane decreased by 2.6% after alkali treatment compared to pristine PVDF membrane decreased by 19.28%. The alkali-resistant performance was mainly attributed to the immobilized SDS. This study provided a facile and scalable method for designing alkali-resistant PVDF membrane, which shows a promising potential in the treatment of alkaline wastewater and alkaline-cleaning PVDF membrane.

UV-Curable Coatings, Have been Widely Used in Machinery, Chemical Engineering, Biology, Medicine, Electronics and so on, due to their Fast Curing, Low Curing Temperature, Low VOC Emissions and Low Energy Cost. however, the Volume Shrinkage during the Curing Process Have a Great Influence on the Performance of the Coating, which Ofen Lowering Coating Adhesive Strength and Accelerating the Aging Process of Coatings Film.The Paper Select Different Kinds of Monomers (EOEOEA, HDDA, TPGDA, NPGDA, TMPTA and EO3- TMPTA) and Light Cured Resin (free Radical Type: Polyester Acrylate Resin 5600, Polyurethane Acrylate UA VP 2396, the Pure Acrylic 6536-1,cationic Resin: Epoxy Cationic Resin Omnilance OC3005) to Prepare the UV Curing Coatings. Study on the Influence of Amount of Monomer and Polymer on Polyreaction Reaction by Using Orthogonal Experimental Design Method in Order to Choose the Monomer and Polymer that has the Least Volume Shrinkage Rate, then Develop Photocureable Coating Based on Free Radical Type and Cationic Resin above. the Results Indicate that the UV-Light Photocureable Coating Prepared by Single Functionality Monomer EOEOEA and the DPGDA that Doesn’t Have Neat Molecular Structure has the Less Volume Shrinkage Rate; however, in the Aspect of Prepolymer, the Preparation of UV-Light Photocureable Coating Based on Polyester Acrylate 5600 has the Least Volume Shrinkage Rate. Rely on the Experiment Results above, Prepare the New Kind of UV-Light Photocureable Coating that has Little Volume Shrinkage Rate.

Using the hydrolysis reaction of TEOS and ethanol to prepare nano-SiO2 sol, and grafting with silane coupling agent WD-20 to introduce double bonds to make a surface modification, the nano-SiO2 sol mixed with the light-cured resin PEA, reactive diluents TPGDA and photoinitiators 1171 under ultrasonicto after dried concentration in vacuum oven, then the composite resin gotten was characterized through FTIR, TGA, UV-Vis and particle size analysis. The results showed as follows: the light-cured resin modified by nano-SiO2 with WD-20 was better in dispersion and stability, and durability, abrasion resistance and other performances of the coating improved significantly which broadened the application range of light-cured resin.

This work successfully prepared an UV curable organic-inorganic hybrid material consisting of organic modified colloidal silica. Applications of UV curable organic-inorganic hybrid materials include abrasion resistant coatings, photo-patternable thin films and waveguides. Colloidal silica containing reactive functional groups were also prepared by reacting organic silane and tetraethyl orthosilicate (TEOS) using sol-gel process. In addition, the efficiency of grafting organic moiety onto silica nanoparticles was investigated by applying TGA and FTIR techniques. Experimental results indicated a strong interdependence between surface modification efficiency and solution pH. Acrylate-SiO2 hybrid formation could result in a shifting of thermal degradation temperature of organic component from about 200°C to near 400°C. In addition, the stability of organic modified colloidal silica in UV curable formula and the physical properties of resulting coatings were discussed. Furthermore, the morphology of organic modified colloidal silica was investigated by performing TEM and SEM studies‥
