The studies on composite membranes demonstrate that they are suitable for PEM applications and can potentially compete with Nafion membranes in terms of performance and lifetime.
According to the obtained results from this study, the SPES–LaCrO3 nanocomposite membranes are promising membranes for PEM fuel cells.
These novel TFC membranes show great potential to compete with commercially available membranes.
Experimental and simulation results indicated that EPDM membranes presented the best performance.
These results indicate that grafted ePTFE films are applicable to positively charged ultrafiltration membranes.
The results of the multi-criteria assessment presented here allow, for the first time, to select at the design stage the most and least advantageous waterproofing solutions. Through the multi-criteria life cycle assessment (combining cost and environmental impacts in the life cycle), it was found that, for all roof types, the bituminous membranes were the best option and the synthetic EPDM membranes presented the highest values.
The reported membranes are therefore suitable for use in HT-PEMFCs.
The results indicate that the CSPIy-TFVBPAx membranes are promising candidates for proton exchange membranes in fuel cell applications.
Compared with the pure PES membranes, the hybrid membranes possess higher flux and good antifouling properties.

What is thermoplastic vulcanizates (TPVs)?4 answersThermoplastic vulcanizates (TPVs) are special classes of thermoplastic elastomers that are formed by dynamically vulcanizing the rubber phase during melt mixing with a thermoplastic matrix phase at elevated temperature. TPVs are suitable for various automotive applications, including under-the-hood applications, due to their high heat resistance and excellent oil resistance properties. The ratio between the elastomer phase and the thermoplastic phase, as well as the morphology of the material, play a significant role in the properties of TPVs, such as elasticity recovery and mechanical properties. The rheology of TPVs is influenced by the long chain branching of the primary constituents, the level of curing, and the amount of crosslinked rubber. Novel TPVs with integrated properties, such as reinforcement, recycling, and shape memory, have been developed using tailored cross-linkers and exhibit improved tensile strength and elongation at break. Additionally, green and non-petroleum-based TPVs have been developed using silica-filled silicone rubber and poly(butylene succinate), offering potential applications in packaging, biomedical devices, and 3D printing materials.
What are the different types of roof sealants that contain latex and polyisoprene?5 answersThere are several types of roof sealants that contain latex and polyisoprene. One type is a synthetic polyisoprene latex, which is produced by polymerizing a monomer containing isoprene in an organic solvent using an organic alkali metal catalyst. Another type is a roof waterproof sealant that is prepared from polysulfide rubber LP, glyceryl monostearate, lead dioxide vulcanized paste, sulfur, water, fumed silica, DBP plasticizer, and titanium dioxide. Additionally, a roof sealing material can consist of EPDM butyl rubber, polychloroprene, a mix of acrylonitrile-butadiene copolymer and PVC or other similar synthetic rubber, a glass fiber intermediate layer, and a rubber, bitumen, and filler substrate adhesive layer. An acrylic copolymer latex sealant composition is another option, which includes an acrylic copolymer, a hydrolyzed organoaminosilane, a surfactant, water, and silica. Lastly, a wellbore sealant composition can contain a modified latex that has undergone a dry particulate state, along with a cross-linking agent.
What is the function of polyethylene plastic in roof and pipe repair?2 answersPolyethylene plastic is used in roofs and pipes for its thermal insulation properties and corrosion resistance. In roofs, plastic pipe elements are combined to form a solar roof that can be heated by the environment when a heat-conveying medium flows through the pipe system. Once the heat-conveying medium is pumped away, the plastic roof provides insulation against heat radiation. In pipe repair, a polyethylene pipe fixing device is used to fix PE pipes of various models. The device consists of a bottom plate, supporting mechanism, and fixing mechanism. The fixing mechanism uses hook-and-loop fasteners to achieve high stability and easy dismounting, saving time and labor. The use of plastic in roofs and pipes provides benefits such as light weight, low thermal conductivity, energy-saving, and convenient molding, making it a widely used building material.
