  • Publication number: 20230330915
    Abstract: A variety of thermoplastic parts are provided with precise micro-scale features and long-range macro-scale reproducibility. By combining the advantages of rigid tool molding and soft tooling into a hybrid tooling, complex and challenging microfeatures can be created in thermoplastic parts with remarkable positional accuracy and reproducibility. The parts described herein can demonstrate orders of magnitude smaller inter-part variations and order of magnitude smaller variations with respect to a master part as compared to conventional hard and soft tooling methods. In some aspects, a plurality of thermoplastic parts having precision micro-scale features and reproducible macro-scale dimensions are provided wherein the precision micro-scale features on each part comprise at least one challenging microfeature; and wherein a mean normalized displacement of the micro-scale features is about or less when measured between the parts in the plurality of thermoplastic parts.

  • Patent number: 11230413
    Abstract: A connection mechanism including a plurality of microstructure features. The connection mechanism includes a first strip, with a plurality of protrusions extending from the first strip, and a second strip, with a plurality of protrusions extending from the second strip. The protrusions define grooves between adjacent protrusions. A pressure sensitive adhesive is provided in at least some of the grooves. When the first and second strips are brought together, the protrusions from one strip are received in the grooves of the other, and some of the protrusions contact the pressure sensitive adhesive, thereby connecting the first and second strips. The connection mechanism can be used as a closure mechanism for a plastic storage bag.

  • Publication number: 20210402659
    Abstract: Thermoplastic forming tools and assemblages are provided for forming thermoplastic components. In particular, thermoplastic forming tools and assemblages are provided for forming thermoplastic components having precision micro-scale features and reproducible macro-scale dimensions. The thermoplastic forming assemblages can include at least a bottom tool and a top tool having a rigid tool body and an elastomer layer conformally coating at least a portion of both rigid tool bodies. The bottom and top tool can be so dimensioned that, when in the closed position, they define a cavity forming the thermoplastic component. The rigid tool bodies provide the reproducible macro-scale dimensions in the thermoplastic component, while the elastomer layers form and release the precision micro-scale features in the thermoplastic component when formed.

  • Patent number: 10683617
    Abstract: A wall covering, a method of producing it and a method of covering a wall. The wall covering comprises a planar substrate, such as a nonwoven base substrate, having a front, and a back facing opposite the front. There is a barrier layer on the back of the substrate and an adhesive layer superimposed on the barrier layer. The adhesive layer comprises a first polymer component, a second polymer component, the first polymer component being a non crosslinked polymer and said second polymer component being a crosslinked polymer exhibiting properties of superabsorbency. The adhesive exhibits when exposed to water, a strength sufficient for binding to a wall substrate and a glide resistance low enough for allowing repositioning of the wall cover by sliding the wallcover on the wall without having to lift it up over a period of time of at least 5 minutes.

  • Publication number: 20180305609
    Abstract: Compositions, methods, and systems including an encapsulated additive comprising a treatment fluid additive at least partially encapsulated by an encapsulating material. The encapsulated additive has a target release profile for release of the treatment fluid additive from the encapsulating material in a specific wellbore environment. The encapsulating material is selected to achieve the target release profile, the target release profile being based on one or more conditions selected from the group consisting of: (1) a target anisotropic pressure that is greater than both an injection anisotropic pressure and an injection isotropic pressure, (2) an erosion number, (3) a temperature-driven degradation, (4) a pressure-driven degradation, (5) an amphiphilic water dispersibility, (6) an amphiphilic oil dispersibility, (7) a chemical flood degradation, (8) a water ingress value, and, (9) a radiation-driven degradation.

  • Publication number: 20180052130
    Abstract: A device and method for detecting presence of a hazardous material in an environment or through a testing material, such as for example, a protective material. The device may include a sensor for detecting presence of the hazardous material. The sensor may comprise or be formed from a conductive polymer, a semi-conductive polymer or an electroactive polymer, the sensor being chemically reactive with the hazardous material to generate a change in electrical resistance in the sensor. The device may further include one or more conductive electrodes attached to the sensor configured to detect a change in resistance in the sensor, and a resistance measuring device electronically connected to the one or more electrodes for receiving data from the one or more electrodes and generating an output based on the data corresponding to an amount of hazardous material detected by the sensor in real-time.
