A method for manufacturing a composite electrode for a metal-air electrochemical cell with a liquid electrolyte of basic pH. A liquid solution comprising a fluoropolymer suspended in a solvent is synthesized, then deposited on the outer surface of a porous structure forming an air electrode. The fluoropolymer comprises SON groups suitable for conducting hydroxyl ions and is capable of forming a membrane impermeable to at least the liquid electrolyte of basic pH. When the liquid solution is applied to the porous structure, the solvent flows through the porous structure and the fluoropolymer is deposited by aggregating into a layer on the outer surface of the porous structure.

Composite air electrode and associated manufacturing method

A process for transferring heat from a heat source to a heat sink, comprising using as heat transfer medium a composition comprising: at least one fluorinated fluid free from functional groups (fluid (H)); at least one functional (per)fluoropolyether (functional PFPE(1)) comprising recurring units (R1), said recurring units comprising at least one ether linkage in the main chain and at least one fluorine atom (fluoropolyoxyalkylene chain), and at least one functional end group chosen between &#x2014;COOH and &#x2014;CONH; at least one functional (per)fluoropolyether (functional PFPE(2)) comprising recurring units (R1) as defined above and at least one functional end group chosen between &#x2014;COCFand its hydroxylated derivative &#x2014;C(OH)CF.

The present invention pertains to a solar cell module comprising at least one photovoltaic element encapsulated between a front layer on its light receiving surface side and a back layer, said front layer comprising at least one layer comprising a tetrafluoroethylene (TFE) polymer [polymer (F)], said polymer (F) comprising: recurring units derived from TFE; and from 15 to 25% wt of recurring units derived from at least one perfluoromonomer [monomer (CM)] chosen among: (i) perfluoroalkylvinylethers complying with formula CF&#x2550;CFOR, in which Ris a C-Cperfluoroalkyl, e.g. &#x2014;CF, &#x2014;CF, &#x2014;CFand/or (ii) perfluoro-oxyalkylvinylethers complying with formula CF&#x2550;CFOX, in which Xis a C-Cperfluorooxyalkyl having one or more ether groups, like perfluoro-2-propoxy-propyl; and (iii) mixtures thereof. Still objects of the invention are a process for the manufacture of the solar cell module as above defined and its use for producing current to external sources, e.g. for powering a fixed-wing aircraft.

Greases comprising a mineral and/or synthetic lubricating oil having an hydrogenated basis, a fluoropolyethereal oil and an organic or inorganic thickening agent, wherein the weight ratio lubricating oil+fluoropolyethereal oil/thickening agent ranges from 97:3 to 80:20 and the weight ratio lubricating oil/fluoropolyethereal oil ranges from 95:5 to 60:40.

Mineral or synthetic, hydrogen-based greases, having improved properties

A process is described for imparting oil- and water-repellency to textile fibers, skin, leather and the like, wherein a composition comprising a functionalized (per)fluoropolyoxyalkylene with silane groups and a phosphoric monoester derived from a (per)fluoropolyoxyalkylene is applied on said materials. As dispersing agent, an hydrophilic organic solvent (for instance an alcohol), optionally in admixture with water can be used. Limpid, stable and easily dilutable formulations are thus obtained, which are capable of imparting very good properties both of oil- and water-repellency. Such properties keep for a long time also after washing both in water by means of detergents and by dry cleaning with organic solvents.

The invention relates to a process for reducing the back migration of the most volatile fractions of perfluoropolyethers during the operation of mechanical vaccum-generating pumps which utilize perfluoropolyethers: use is made of perfluoropolyethers containing not more than 0.1% by weight of fractions having a molecular weight lower than or equal to 1,500 and not more than 1.3% by weight of fractions having a molecular weight lower than or equal to 1,800.

The cross-linking or curing of thermosetting resins and of hot curable elastomers is carried out by heating the material or the article comprising the resin (or the elastomer) by saturated vapor of the commercial perfluoropolyether having an average boiling point corresponding to the temperature necessary for the cross-linking and having a point range not exceeding 12.degree. C. (measured according to ASTM D 1078) in the presence of a chlorofluorohydrocarbon secondary vapor.
