A material for adhesion prevention can be adhered to biological tissue with certainty and has improved tissue adhesiveness and biodegradability. Such material for adhesion prevention is composed of: a 1- to 1,000-&#x3bc;m-thick water-soluble support layer comprising a water-soluble polymer; and a 1- to 1,000-&#x3bc;m-thick adhesion prevention layer comprising a biodegradable polymer. The biodegradable polymer has a structure in which a branched polyalkylene glycol comprising 3 to 8 terminal hydroxyl groups per molecule is bound to a polyhydroxy alkanoic acid, and a mass ratio of the branched polyalkylene glycol relative to the total mass is 1% to 30%.

Material for adhesion prevention

The present invention relates to a process for the preparation of films of conductive polymers, by the technique so-called roll-to-roll, which allows to obtain freestanding films having advantageous features such as toughness, flexibility, ability to adhere to different substrates, a submicron thickness and a very high ratio surface area/thickness; the present films are suitable for use in several technological applications, in particular for the development of biosensors, and in the production of flexible electronic components with large surface, suitable for wearable devices and also intended for contacting skin.

Process for preparing free-standing films of conductive polymers

Provided are an electronic device employing a polymer nanosheet, having an electronic element and a conductive wiring that are connected to each other in a solder-free manner, and exhibiting a high conformability and adhesiveness to an object for attaching including a biological tissue such as skin; and a method for manufacturing the same. The electronic device includes the electronic element; and the polymer nanosheet adhering to the electronic element. Specifically, the polymer nanosheet adheres to the electronic element in a manner such that one surface of the electronic element is entirely covered by the polymer nanosheet. It is preferred that the polymer nanosheet have a thickness of smaller than 1 &#x3bc;m. Further, a conductive wiring capable of being electrically connected to the electronic element; and a power source for supplying power to the electronic element, may also be formed on the polymer nanosheet.

A polymer film can be adjusted to movement or a fine uneven surface of a living body and has excellent ability to adhere to a biological tissue. The polymer film includes a block copolymer having a structure in which branched polyalkylene glycol and polyhydroxyalkanoic acid are bound to each other, wherein the polymer film has a film thickness of 10 to 1000 nm. The branched polyalkylene glycol has at least three terminal hydroxyl groups per molecule, the mass percentage of the branched polyalkylene glycol relative to the total mass of the block copolymer is 1% to 30%, and a value obtained by dividing the average molecular weight of polyhydroxyalkanoic acid in the block copolymer by X that is the number of terminal hydroxyl groups present per a single molecule of the branched polyalkylene glycol is 10000 to 30000.

Polymer film and antiadhesive material using the same

A method for preparing a thin film polymer structure having a functional substance on an A surface and a B surface of the film, the polymer structure being obtained by: (a) adsorbing polyfunctional molecules to a region of an arbitrary shape in an interface between a substrate body and a liquid phase; (b) polymerizing and/or crosslinking the adsorbing polyfunctional molecules to form a polymer thin film; (c) bonding a functional substance to the A surface of the formed thin film and then forming a soluble support film on the A surface; (d) exfoliating the thin film and the soluble support film from the substrate body; and (e) bonding to the B surface of the thin film a functional substance identical to or different from the functional substance bonded to the A surface and then dissolving the soluble support film with a solvent.
