Abstract:
Methods for making formable polymers including elastomeric gels resulting in a formable polymer having air voids or pockets are disclosed. The methods can include forming a formable polymer around salt particles or other dissolvable particles, permitting the formable polymer to solidify, then reducing the salt or other dissolvable particles by use of water or a solvent or melting, leaving air pockets or voids in the formable polymer.
Abstract:
A method of manufacturing a flexible intrinsically antimicrobial absorbent porosic composite controlling for an effective pore size using removable pore-forming substances and physically incorporated, non-leaching antimicrobials. A flexible intrinsically antimicrobial absorbent porosic composite controlled for an effective pore size composited physically incorporated, high-surface area, non-leaching antimicrobials, optionally in which the physically incorporated non-leaching antimicrobial exposes nanopillars on its surface to enhance antimicrobial activity. A kit that enhances the effectiveness of the intrinsically antimicrobial absorbent porosic composite by storing the composite within an antimicrobial container.
Abstract:
The present invention provides a polyurethane implant that is porous and degradable, and act as a scaffold for the repair of damaged tissue. Importantly, the implant of the present invention is biocompatible with the degradation products of the implant causing minimal immune or cytotoxic reaction. The present invention also provides for a method of making these biocompatible implants.
Abstract:
The invention relates to a porous PEEK polymer element having a porous PEEK polymer structure and at least one trimodal pore distribution. The invention also relates to a method for producing said porous PEEK polymer element, according to which: a) a PEEK polymer is brought into contact with a composition comprising at least one organic solvent, b) the polymer and composition are heated to a temperature at which the PEEK polymer dissolves, c) at least one pore-forming agent is added, d) the mixture produced in c) is cooled to a temperature at least equal to, or lower than, the temperature at which the PEEK polymer precipitates, e) said cooled mixture is shaped to form a shaped object, f) the organic solvent and pore-forming agent are removed, and g) the PEEK polymer element is recovered.
Abstract:
Method for continuously producing sponge bodies (1) made of regenerated cellulose using at least partially agglomerated pore inducers made of sodium sulphate decahydrate, in which at first a viscose solution is provided, the pore inducer is added to said viscose solution, the viscose solution is laid onto a conveyor belt which is continuously moving, wherein the viscose solution is led through baths on the conveyor belt, resulting in a porous mass made of regenerated cellulose.
Abstract:
The invention relates to a particle-stabilised foam wherein the particles are derived from a polymer latex dispersion and the foam substantially retains its structure on drying.
Abstract:
Various embodiments of snacks of orally soluble edible films are disclosed. The snacks may include one or more layers of film that is orally soluble and disintegrates quickly upon placement in a human mouth without leaving substantial residue that can be felt by the human tongue or which needs to be swallowed or ejected from the mouth.
Abstract:
The invention discloses a method for manufacturing alveolate cellulose products (sponges, sponge-cloths...), from a cellulose raw material, which comprises: dissolving at least partially the said cellulose raw material in an intrinsic solvent; incorporating, under agitation, into the resulting mixture an effective amount of at least one pore forming agent; the said pore forming agent(s), compatible with the cellulose mixture, being suitable for generating, when their action develops, a macro- and a microporosity; gelling the consistent homogeneous mass thus obtained; treating the said gelled mass under conditions where the dissolved cellulose precipitates and the action of the pore forming agent(s) present develops. The said method is an advantageous alternative to the polluting viscose method. The products obtained have properties quite similar to those of the products obtained by the said viscose method. The said new products are part of the invention.
Abstract:
Soft actuators are fabricated from materials that enable the actuators to be constructed with an open-celled architecture such as an interconnected network of pore elements. The movement of a soft actuator is controlled by manipulating the open-celled architecture, for example inflating/ deflating select portions of the open-celled architecture using a substance such as compressed fluid.
