Sponge-like pore (cellular pore) structure of ultrafiltration membrane has special advantages on rejection and anti-pressure performance. The cover by Lei Zhang and colleagues shows a SEM image of sponge-like pore structure of PES UF membrane, which was prepared by adding some non-solvent additives. The membrane with fully sponge-like structure retained good operation stability for long time at high pressure. Inevitably, the permeate flux was decreased because of greater mass transfer resistance. DOI: 10.1002/app.47525.

Relationship on structure and properties of polyurethane modified Diels–Alder addition polymer

D-A adducts have characteristics that polymerizing in low temperature and depolymerizing in slightly high temperature. To explore whether the material has reversible self-healing properties, GPC were used to characterize the properties of polymerization-depolymerization-repolymerization material. The GPC of L-DAPU-8 was measured and the experimental results are as follows. It can be seen that the relative molecular weight decreases rapidly after 40 minutes of depolymerization, and the relative average molecular weight of the r-DA products gradually increase after 16 hours of repolymerization, which indicates that D-A products undergo depolymerization-repolymerization and have self-healing properties.

Investigation of ureido-attached vinyl MQ silicone resin on tracking and erosion resistance of addition-cure liquid silicone rubber

Ureido-attached vinyl MQ silicone resin (U-VMQ) was synthesized for enhancing the tracking and erosion resistance of addition-cure liquid silicone rubber (ALSR). With 2 phr of U-VMQ containing 2.5wt% of vinyl content, the ALSR successfully passed the inclined plane tracking (IPT) at 4.5 kV, and the electrical erosion rate was only 0.13%.

Effect of nonsolvent additives on PES ultrafiltration membrane pore structure

In this study, the effect of different non-solvent additives on the pore structure of PES ultrafiltration membrane had been evaluated. The pore structure would gradually become sponge-like structure with moderate addition of non-solvent additive. The sponge-like structure showed excellent properties in operation stability.
