The invention relates to a textile structure, intended to be used as a sound-absorbing structure in acoustic ceiling panels and/or acoustic wall panels, consisting of It also relates to a process for manufacturing such a textile structure and to a ceiling panel or wall panel coated on one of these faces with such a textile structure.

Textile structure based on glass fibers for acoustic ceiling or acoustic wall panel

The present invention is directed to an entity comprising a particle attached to at least one polymer M through one or several supramolecular interactions -A-B- constituted by 2 to 8 hydrogen bonds X-H-Y, wherein A and B are functional groups respectively grafted to P and M thus forming the particle-containing entity P-(A-B-M)x with x being greater than or equal to 1, functional group(s) B being positioned at one end of the polymeric chain of polymer M, X and Y are heteroatoms present in A and B functional groups, H is hydrogen, and M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500. The invention is also directed to a method for preparing this particle-containing entity P-(A-B-M), a method for sequentially forming and breaking the supramolecular interactions -A-B- in said particle-containing entity P-(A-B-M)and dispersions comprising the same.

Universally dispersible particles containing hydrogen bonds

The present invention is directed to a particle-containing entity P-(A--B-M)wherein P is a solid particle attached to at least one polymer M through one or several reversible covalent bonds -A---B-, wherein A and B are functional groups respectively grafted to P and M thus forming the P-(A---B-M)particle-containing entity with x being greater than or equal to 1, M has a degree of polymerization comprised between 5 and 1000, preferably ranging from 5 to 500, and wherein the reversible covalent bond -A---B- is chosen among an imine, a disulfide, a boronic ester or an acetal. The invention is also directed to a method of preparing this particle-containing entity, a method for sequentially forming and breaking the reversible covalent bond -A---B- in said particle-containing entity P-(A---B-M)and dispersions comprising same.

Particles containing reversible covalent bonds which may be sequentially formed and broken multiple times
