Definitions
- the present invention relates to a process for the preparation of fibrous superhydrophobic substrates, superhydrophobic fibrous substrates and the use of such substrates.
- a material is considered superhydrophobic when the contact angle of a drop of water deposited on its surface is greater than 140 degrees.
- Such materials have interesting properties in a wide variety of fields, including clothing, stationery or paints.
- the invention provides a process for preparing a fibrous superhydrophobic substrate, comprising the following successive steps: preparation of hydrophobic microparticles of heart-shell type, said microparticles having a polyurethane core and a polydimethylsiloxane bark or polybutadiene; depositing, on the fibrous substrate, a liquid suspension of said microparticles in an organic solvent.
- fibrous substrate is meant any material consisting of synthetic or natural fibers.
- Microparticle means particles of micrometric size.
- hydrophobic core-shell microparticles having a polyurethane core and a bark formed of a polystyrene-poly (ethylene oxide) copolymer, a hydroxypolystyrene, or poly (butyl acrylate) have been synthesized by the inventors, as described in the following publications: B. Radhakrishnan et al., Colloid Polym Sci (2002), 280, 1122-1130, and B. Radhakrishnan et al., Colloid Polym Sci (2003), 281, 516-530. However, these particles, once deposited on fibrous substrates, did not give said substrates a superhydrophobic character.
- the first step of the process according to the invention preferably involves a stepwise polymerization method in a medium dispersed in an organic solvent, a first monomer consisting of a diol, for example ethane-1,2-diol, and a second di-isocyanate monomer, for example tolylene di-isocyanate, in the presence of polydimethylsiloxane (PDMS) or polybutadiene which acts as a reactive stabilizer.
- PDMS polydimethylsiloxane
- the organic solvent used for the preparation of the microparticles may be cyclohexane or supercritical carbon dioxide.
- the microparticles obtained have a diameter generally of between 0.5 and 5 microns.
- the size of the particles is adjusted by varying various parameters: the mass percentage of the reactive stabilizer, the stirring speed, the rate and order of addition of the monomers, the molar mass of the reactive stabilizer and the functionality of the stabilizer. reagent.
- the fibrous substrate that is to be made superhydrophobic hereinafter referred to as the substrate to be treated, is made of natural fibers selected from the group comprising cellulose, wool, cotton, silk, and can be filter paper.
- the substrate to be treated consists of synthetic fibers selected from the group comprising polyamides and polyesters, and may have a porosity of between 1 and 10 microns.
- the substrate is a polyamide fabric.
- This deposition may be carried out for example by filtering the suspension of microparticles through the fibrous substrate, or by soaking the fibrous substrate in the microparticle suspension, then evaporation of the solvent, or by deposition of the suspension on the fibrous substrate and then evaporation of the solvent.
- the subject of the invention is a superhydrophobic fibrous substrate in which the fibers are impregnated with core-shell microparticles, said microparticles having a polyurethane core and a polydimethylsiloxane or polybutadiene bark.
- the microparticles have a diameter generally of between 0.5 and 5 microns.
- the substrate is for example made of a polyamide fabric or filter paper. Depending on its nature, it can be used for the manufacture of textiles for clothing, or for the manufacture of coatings for printing.
- Example 1 relates to the preparation of hydrophobic microparticles, and the following examples relate to the deposition of microparticles on different substrates.
- Polyurethane particles having a core-shell structure are prepared by a process in dispersion in cyclohexane, in the presence of polydimethylsiloxane.
- the reactive stabilizer PDMS-OH, molar mass 4670 g. mol "1 (0.5 g, ie 16.7% by weight), the monomer ethane-1,2-diol (0.6 g) and cyclohexane (20 g) are introduced into the reactor and then left at 60 ° C. with stirring for a few minutes
- the tolylene diisocyanate comonomer (1.9 g) is then added and the reaction mixture is stirred for at least 6 hours.
- the latex obtained is recovered, centrifuged, and then the particles are dispersed again in cyclohexane. This operation is repeated twice.
- the particles obtained are characterized by scanning electron microscopy (SEM).
- SEM scanning electron microscopy
- Figure 1 shows a SEM image of these particles, whose diameter is equal to 2.2 microns.
- the process was repeated to obtain particles having a diameter of 3.5 and 4.2 ⁇ m respectively, using a weight percentage of polydimethylsiloxane equal to 9% and 4%, respectively.
- Example 2
- the test was reproduced successively with polyamide webs having a porosity of 1 .mu.m, 5 .mu.m and 10 .mu.m respectively, and with microparticles having a diameter of 2.2 .mu.m, 3.5 .mu.m and 4.2 .mu.m.
- FIGS. 2a and 2b show clichés obtained at two different scales, the side of the square formed by a plate representing respectively 147 microns and 37 microns, for the fabric having a porosity of 1 ⁇ m treated with a suspension of particles having a diameter of 2.2 ⁇ m.
- Example 3 Embodiment of the process with a substrate consisting of filter paper
- Example 4 A process analogous to that of Example 2 was carried out using a filter paper instead of a polyamide cloth. Tests were carried out with particles having a diameter of 2.2 ⁇ m, 3.5 ⁇ m and 4.2 ⁇ m. A homogeneous deposition which respects the surface topology of the filter paper is obtained, as illustrated in FIGS. 3a and 3b, which show scanning electron microscopy photographs obtained at different scales, the side of the square formed by a plate representing respectively 147 microns and 37 microns, for filter paper treated with a suspension of particles having a diameter of 3.5 microns.
- FIGS. 3a and 3b show scanning electron microscopy photographs obtained at different scales, the side of the square formed by a plate representing respectively 147 microns and 37 microns, for filter paper treated with a suspension of particles having a diameter of 3.5 microns.
- Example 4
- FIGS. 4 to 8 are optical microscopy photographs showing a drop of water deposited respectively on the following substrates: FIG. 4: 5 ⁇ m porosity polyamide fabric and 2.2 ⁇ m diameter particles; FIG. 5: polyamide fabric having a porosity of 1 ⁇ m and particles with a diameter of 2.2 ⁇ m; FIG. 6: polyamide fabric having a porosity of 1 ⁇ m and particles with a diameter of 4.2 ⁇ m; FIG. 7: filter paper and particles with a diameter of 2.2 ⁇ m; FIG. 8: filter paper and particles with a diameter of 3.5 ⁇ m.
