Definitions
- the present invention relates to a new process for the preparation of films based on crosslinked poly (ethylene oxide), the films thus obtained, as well as their use in particular as biomaterials.
- hydrogels are three-dimensional macromolecular networks which retain large quantities of aqueous liquids, and which, because of their particular physicochemical properties, have found numerous applications in fields as varied as the food, pharmaceutical or cosmetic.
- hydrogels those based on poly (ethylene oxide) have been the subject of significant recent developments, in particular because of their high potential for pharmaceutical applications.
- crosslinking of poly (ethylene oxide) by gamma radiation has been described in particular in US patents 3,264,202 and 3,419,006 for pure poly (ethylene oxide) and in US patents 3,898,143, 3,993,551, 3,993,552 and 3,993,553 for mixtures of poly (ethylene oxide) and a water-soluble polymer of natural or synthetic origin.
- the crosslinking of dry poly (ethylene oxide) films by ultraviolet radiation has been recommended in the process described in document US H 1666 for the preparation of salified complexes finding application in the field of high energy batteries. More specifically, the method described in this prior document comprises the steps consisting in: a) dissolving poly (ethylene oxide) alone or as a mixture with poly (methylene oxide) in a polar organic solvent, in the presence of a photo-initiator; b) drying the solution thus obtained at 60 ° C under reduced pressure for 12 hours to obtain a film with a thickness of less than 0.5 mm; c) subjecting the dry film thus obtained to ultraviolet radiation with a wavelength between 190 nm and 350 nm for a period sufficient to allow crosslinking.
- Such copolymers can be block (b) or random (r) or else grafted.
- the process according to the invention can be implemented with a wide variety of copolymers, in particular of copolymers of ethylene oxide and of propylene oxide (OP) or also of copolymers of ethylene oxide. and butylene oxide (OBu).
- these copolymers will have a molecular weight of between 100,000 and 4,000,000, preferably between 200,000 and 2,000,000.
- the proportion of ethylene oxide in the copolymer will advantageously be of the order of at least 90% by weight relative to the weight of the copolymer.
- the water-soluble polymer optionally used with poly (ethylene oxide) can be any water-soluble polymer conventionally known to those skilled in the art.
- said water-soluble polymer is a polysaccharide.
- an alginate is sodium alginate.
- drying steps are generally carried out at room temperature when the solvent system consists of an organic solvent (step b1) and in an oven under reduced pressure at 35 ° C. for 4 hours, when the solvent system consists of water or a water-organic solvent mixture (step b2).
- Samples of rectangular shape were cut, fixed on a support of the polyester sheet type, weighed and placed in a closed container (desiccator) containing water in its lower part.
- the homogeneous viscous solution was poured into a glass Petri dish (220 ⁇ m thick) which was kept in the dark for a sufficient time to allow the solvent to evaporate in the open air.
- Films were thus prepared from mixtures of mass ratios of 9: 1, 7: 3 and 5: 5 having a thickness of 150 to 250 ⁇ m.
- Samples of rectangular shape were cut, fixed on a support of the polyester sheet type, weighed and placed in a closed container (desiccator) containing water in its lower part.
- films based on poly (ethylene oxide) and polysaccharide were prepared using the experimental protocol indicated above, with the exception of the step leading to the absorption of water.
- PETA -2 pentaerythritol tetraacrylate
- TMPTM trimethylolpropane trimethacrylate
- TEGDM tetra (ethylene glycol) dimethacrylate
- Amphiphilic, random and block copolymers of different poly (ethylene oxide) / poly (propylene oxide) ratios have been prepared according to a technique known in the literature. After characterization, these copolymers were used for the preparation of crosslinked films according to the invention.
- Each sample was kept in the desiccator at 30 ° C for a defined period of time to obtain the desired water content.
- the amount of water absorbed was determined by weighing.
- the samples were irradiated at 25 ° C for 30 min using a 150 W mercury lamp which emits white light of which 28% of the energy emitted covers the wavelength range of ultraviolet .
