| 20120033173 | MULTIFUNCTIONAL OPTICAL SENSOR - The invention relates to a multifunctional optical sensor, having at least 2 areas which independently react to different input parameters, the sensor comprising a substrate and a polymeric layer comprising polymerized liquid crystal monomers having an ordered morphology, wherein the color, the reflectivity or the birefringence of the sensor changes due to a change of the morphology, wherein said change of the morphology is caused by physical contact with a chemical agent such as a gas or liquid a change of temperature, or passage of time. The invention also relates to a process for the preparation of the sensor and for the use of a film comprising a single substrate, a layer having a cholesteric liquid crystalline structure for application in labels for packaging of perishable goods, food, fine chemicals, bio-medical materials. | 02-09-2012 |
| 20100279098 | POLYMERIC MATERIAL COMPRISING MULTIPLE CAVITIES - The invention relates to a polymeric material having an anisotropic shape and comprising multiple cavities, wherein said cavities comprise a functional liquid. The invention also relates to a process of making the polymeric material from an emulsion of a functional liquid with a polymer in solution, in the melt or a polymer precursor which reacts to obtain the polymeric material having cavities filled with functional liquid. | 11-04-2010 |
| 20100087929 | SHAPED PART OF AN ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE - Shaped parts of ultra high molecular weight polyethylene (UHMWPE) are made by a process comprising melt processing, wherein a) the UHMWPE has a weight average molecular weight (Mw) of at least 1*106 g/mol, b) during the shaping the storage plateau modulus of the UHMWPE (G*) is kept at a value of at most 1.5 MPa, c) whereafter, before the cooling, the G* is raised to its final value. The shaped parts may advantageously be used in medical applications, e.g., as an element of a hip or knee prosthesis. | 04-08-2010 |
