摘要: Superhydrophobic films from plastic waste and a fabrication method thereof are provided. Superhydrophobic films with variable thickness, comprising a base and top layer, can be created using semi-crystalline polymers, including virgin, recycled, or waste forms. The fabrication process utilizes 60% of total plastic waste, resulting in films with contact angles between 120° to 160°, tensile strength ranging from 1 MPa to about 70 MPa, and thickness ranging from 20 μm to about 5 mm. Superhydrophobic films may impart protective water-repellent properties against the elements.

摘要: A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

摘要: Superhydrophobic films can be prepared from a stream of plastic waste (i.e., derived from post-consumer and/or industrial waste) by a method comprising: dissolving first semi-crystalline polymers in a solvent to form solution1; pre-heating a solid substrate to below a boiling point of the solvent; applying solution1 onto the substrate using spin-casting to obtain a porous blended-polymer layer with fragile structure; annealing the porous blended-polymer layer to above the melting point of the first semi-crystalline polymers to strengthen the porous blended-polymer layer's internal structure by closing pores and decreasing surface roughness, thereby obtaining a strong non-porous base support layer; and dissolving second semi-crystalline polymer in a solvent to form solution2; pre-heating the non-porous base layer to a temperature below a boiling point of the solvent; applying solution2 onto the non-porous base layer to obtain a top porous layer crosslinked with the non-porous base layer; and peeling off the freestanding superhydrophobic film.

摘要: A plastics moulding process is provided in which a first (2) and a second plastic part (3) are moulded such that a contact surface is formed between the two parts. The first part (2) is moulded firstly and, whilst at least the contact surface is still in a liquid or plastic state, an attachment promoting powder (16) that is compatible with, and has the characteristic of attaching to, the plastic of the first part (2), is applied to it. Thereafter, the second part (3) is moulded so as to contact the first part at the contact surfaces such that as it solidifies, it attaches to the attachment promoting powder (16) and thereby to the first part (2). The second part (3) may be a plastic foam filling for a hollow first part (2). The attachment promoting powder (16) may be a suitable grade of diatomaceous earth or a natural or synthetic equivalent.
