The present disclosure relates to optically transparent plant-derived products that are capable of dissolution in water.

A breathable biodegradable volatile corrosion inhibitor polyester composition comprises one or more biodegradable homopolymer polyesters and/or one or more biodegradable random copolymer polyesters, one or more volatile corrosion inhibitors (VCI), and one or more fillers wherein said composition has a higher water-vapor transmission rate than polyethylene.

The disclosure provides a biodegradable material and its preparation method and application, which solves the problems of a harsh preparation condition of a biodegradable material, a rough surface on a film formed by the prepared biodegradable material, pores existing in a cross section. The biodegradable material of the present disclosure is high in preparation efficiency and simple in preparation process and energy consumption saving without necessary high-temperature and high-pressure conditions. There is no obvious difference between its degradation performance and the degradation performance of the biodegradable material prepared by the conventional high-temperature high-pressure method. The biodegradable material is suitable for preparing a film to be applied to a field of packaging materials. The prepared film may be completely degraded in about 15 days. The prepared film is smoother on surface and more excellent in toughness and malleability compared with the film prepared under conventional high-temperature and high-pressure conditions.

A biodegradable and/or compostable device is formed of a plant-based biopolymer in a range of 50 to 80% by volume and a polylactic acid (PLA) in a range of 10 to 30% by volume.

A multi-layer polymer film comprising at least one middle layer A, the polymeric constituents of which are soluble in aqueous solution, and in each case at least one substantially water-impermeable covering layer B, C arranged above and below the at least one middle layer A, wherein the layers A, B and C independently of each other in each case comprise at least one thermoplastic polymer and at least one of the covering layers B and C comprises at least one polyhydroxyalkanoate is presented and described. Processes for the production of the multi-layer polymer film according to the invention and its use for the production of molded parts, films or bags are furthermore presented and described.

A mycological biopolymer material is subjected to treatment in one or more solutions that work to enhance and/or retain the inherent material properties of the material. In one embodiment, the solution is an organic solution; in another embodiment, the solution is an organic solvent with a salt; in another embodiment, the solution is an organic solvent phenol and/or polyphenol; and in another embodiment, a series of such solutions is used.

The biodegradable composite insulation material is made from date palm leaf fibers and powdered okra. The date palm leaf fibers have a concentration of between 50 wt % and 90 wt % of the biodegradable composite insulation material, and the powdered okra has a concentration of between 10 wt % and 50 wt % of the biodegradable composite insulation material. The biodegradable composite insulation material is prepared by mixing date palm leaf fibers and powdered okra, in the above concentrations, to form a mixture. This mixture is then wetted with water, added to a mold, and heated under pressure to form a compressed article. The compressed article is then dried to form the biodegradable composite insulation material.

The present invention relates to a multicomponent plastic product comprising at least two different thermoplastic materials, wherein a first thermoplastic material comprises a first thermoplastic polymer, and a second thermoplastic material comprises at least a second thermoplastic polymer and at least one degrading enzyme able to degrade the first thermoplastic polymer. The second thermoplastic material has a transformation temperature lower than the transformation temperature of the first thermoplastic material, and the first and second plastic materials are at least partially adjacent in the multicomponent product.

A molded hook surface fastener having a base plate and a large number of hook engaging elements projecting from a surface of the base plate, wherein both the base plate and the hook engaging elements is made of a resin mixture comprising polybutylene succinate (A) as a continuous phase and starch (B) as a dispersed phase, and satisfying the following requirements (1) to (3) simultaneously: (1) the dispersed phase comprises polyvinyl alcohol (C); (2) the starch (B) comprises a modified starch, and an amylose content of the starch (B) is 45% by weight or more; and (3) the hook engaging element tapers from a surface of the base plate toward a distal end portion and gradually bends from its middle such that the distal end portion faces a direction slightly approaching the surface of the base plate,
is produced without breaking the hook engaging element during the pultrusion molding and is decomposed in the natural environment and does not bring about environmental destruction when discarded.

The present invention provides a hydrogel for comprising a biodegradable polyphosphazene polymer, a radiation-sensitive diselenide cross-linker; and one or more payloads releasably loaded within the hydrogel. The present invention further provides methods for radiosensitizing target tissues such as tumors and providing sustained delivery of therapeutics triggered by irradiation. In another aspect, the present invention provides a method that includes: introducing the hydrogel, as describes herein, adjacent to malignant or marginal tissue; and administering radiation to the hydrogel, thereby disrupting the selenocystamine cross-linkers and releasing the one or more payloads.
