Embodiment Construction

[0012] As defined in claim 1, shape memory composites according to the present invention exhibit a structure comparable to that of conventional shape memory polymers, including hard segments / chemical sites and switching segments as disclosed in known systems. The composite according to the invention is characterized in that the switching phase of the composite comprises segments according to the definition of switching segments of shape memory polymers of known systems, i.e. organic moieties, i.e. oligomer or polymer segments, whereas The hard phase / chemical network of the shape memory composite according to the invention is selected from solids, including organic and inorganic solids, preferably inorganic solids, which may be in the form of particles, fibers, filaments, platelets, sheets, including nanoparticles and microparticles. exist in the form of membranes. The term solid as used herein in relation to the hard phase / chemical site of the shape memory composite includes p...

Abstract

The present invention concerns shape memory composites, methods of preparing same and the use of these composites, for example, for products prepared by injection moulding techniques or coating applications.

Description

technical field [0001] The present invention relates to shape-memory composites, processes for their preparation and the use of these composites, for example, for products produced by injection molding technology, extrusion, solution technology or coating applications. Background technique [0002] The shape memory effect or shape memory function is a known phenomenon and is realized by metal alloys as well as polymers. The shape memory function is a function of a material that temporarily fixes the material to a second shape after being elastically deformed, and only restores the original (first) shape after an external stimulus is applied. Beneficial and interesting properties of shape memory materials lie in particular in the possibility to induce the desired shape change by appropriate external stimuli to return to the original shape after deformation and to deform and program these materials so that highly specific conformations can be obtained. Possibility of shape an...
