Apparatus and methods for creating multi-layered lightly-laminated films with increased or maintained strength. An increased level of strength is achieved by bonding adjacent layers of the multi-layer film together in a manner that the bond strength of the laminated layers is less than a strength of a weakest tear resistance of the individual first and second film layers. The inventors have surprisingly found that such a configuration of light bonding provides increased and unexpected strength properties to the multi-layer film as compared to a monolayer film of equal thickness or a multi-layer film in which the plurality of layers are tightly bonded together.

Methods for fastening nanoscale structures within an anchoring structure to form a nanostructure composite and nanostructure composites formed therefrom. A primary fluid layer is formed on an anchoring substrate. Nanostructures are provided on an initial substrate, the nanostructures having a defined height and orientation with respect to the initial substrate. The nanostructures are introduced to a desired depth in the primary fluid layer, such that the orientation of the nanostructures relative to the growth substrate is substantially maintained. The primary fluid layer comprises one or more fluid layers. Ones of multiple fluid layers are selected such that when altered to form an anchoring structure, a portion of the anchoring structure can be removed, permitting exposure of at least a portion of the nanostructures from the anchoring structure in which they are affixed. The growth substrate is removed. Ends or other parts of nanostructures may be exposed from the anchoring structure.

Automobile panel repair laminates include a pressure sensitive adhesive bonded to a support backing. The support backing may be constructed of various materials such as plastically deformable polymeric materials including thermoplastic or thermoset materials and may have various thicknesses depending upon the desired conformability and rigidity necessary for the repair. The support backing may be bonded to the pressure sensitive adhesive by applying adhesion promoters such as solvents. The repair laminate is applied to a back or non-aesthetic side of the automobile panel, and the front side is repaired using standard techniques for filling and finishing.

Disclosed is a multilayer film for a strain-free laminate which is used for flexible TFT substrates or the like. Also disclosed are a laminate obtained by arranging such a multilayer film on a substrate made of an inorganic material, and a method for producing such a laminate. Specifically disclosed is a multilayer film wherein an adhesive resin layer which can be adhered to inorganic materials is arranged on a film base made of a resin. This multilayer film is characterized in that the average thermal expansion coefficient between 60°C and 80°C measured while heating the multilayer film from 30°C to 130°C is larger by 30-400 ppm/°C than the average thermal expansion coefficient between 60°C and 80°C measured while reheating the multilayer film, which is once heated to 130°C and then cooled to 30°C or less, from 30°C to 130°C. Also specifically disclosed is a laminate obtained by bonding such a multilayer film on at least one surface of a substrate which is made of an inorganic material. Further specifically disclosed is a method for producing such a laminate wherein the multilayer film and the substrate of inorganic material are bonded at a temperature not less than 40°C but not more than the glass transition temperature of a resin constituting the adhesive resin layer of the multilayer film.

Spunbonded fabrics are formed by melt-spinning a blend comprised of a major amount of an uncured substantially amorphous polyarylene sulfide and a minor amount of a crystallinity enhancer to obtain a nonwoven mass of filaments, and thereafter passing the nonwoven mass of filaments through a nip of heated calendering rolls to form a spunbonded fabric therefrom having at last substantially crystalline surface regions. Preferably, blending minor amounts of a polyolefin (e.g., polypropylene) with an uncured polyarylene sulfide (e.g., polyphenylene sulfide) allows spunbonded nonwoven fabrics to be formed which do not suffer from the drawbacks noted above. More specifically, spunbonded fabrics formed of a blend of PPS and polypropylene may be calendered (bonded) at temperatures greater than between about 110 to about 125 ° C (preferably greater than about 140 ° C), and exhibit lengthwise and widthwise shrinkage after heatsetting at 120 ° C for 3 minutes which is less than about 5%.
摘要:
A laminated panel (23) comprises a fusible layer (23A) having an upper surface. A mesh layer (23A, A1) has an encapsulated portion enclosed in the fusible layer so as to be below the upper surface of the fusible layer (23A). An embossed portion (A1) protrudes from the upper surface of the fusible layer (23A). A method (10) of forming a laminated panel with the fusible layer and the mesh layer comprises the steps of: i) heating the fusible layer (23A) to fuse a portion of the fusible layer; and ii) pressing only selected portion of the mesh layer against the fusible layer to provide for the formation of an embossed pattern (A1) on the resulting laminated panel (10).
摘要:
The weatherability of a multilayer article comprising a top layer and a substrate layer is enhanced by the addition of a fiber in a thermoplastic polymer substrate. The top layer includes at least one thermoplastic polymer comprising structural units derived from at least one 1,3-dihydroxybenzene and at least one organodicarboxylic acid. Processes for making the aforementioned multilayer article are also provided in the present invention.
