Abstract
(EN) The use of a sol comprising a solvent, an alkoxide and a catalyst to prepare a water impermeable product is provided. Also provided is a water impermeable fibre-based product prepared using a sol. Further provided is a sol comprising a solvent, an alkoxide, a biopolymer, and a catalyst. A method of making a sol comprising a solvent, an alkoxide, a biopolymer, and a catalyst is also provided. The method comprises: a) dispersing a biopolymer in a solution comprising a catalyst and then adding an alkoxide; b) dispersing an alkoxide in a solvent, adding a catalyst and then adding a biopolymer; or c) dispersing an alkoxide in a solution comprising a catalyst and then adding a biopolymer. Yet further provided is a coated product wherein the product has been coated with a sol comprising a solvent, an alkoxide, a biopolymer, and a catalyst. A powder derived from a sol as described herein is also disclosed.
(FR) L'invention concerne l'utilisation d'un sol comprenant un solvant, un alcoxyde et un catalyseur pour préparer un produit imperméable à l'eau. L'invention concerne également un produit à base de fibre imperméable à l'eau préparé à l'aide d'un sol. L'invention concerne en outre un sol comprenant un solvant, un alcoxyde, un biopolymère et un catalyseur. L'invention concerne également une méthode de fabrication d'un sol comprenant un solvant, un alcoxyde, un biopolymère et un catalyseur. La méthode comprend : a) la dispersion d'un biopolymère dans une solution comprenant un catalyseur puis l'ajout d'un alcoxyde; b) la dispersion d'un alcoxyde dans un solvant, l'ajout d'un catalyseur et ensuite l'ajout d'un biopolymère; ou c) la dispersion d'un alcoxyde dans une solution comprenant un catalyseur, puis l'ajout d'un biopolymère. L'invention concerne en outre un produit revêtu, le produit ayant été revêtu d'un sol comprenant un solvant, un alcoxyde, un biopolymère et un catalyseur. L'invention concerne également une poudre dérivée d'un sol tel que décrit ici.
