摘要:
The present invention concerns a novel low-temperature thermoplastic wood-biopolymer composite comprised of small wood particles and a polycaprolactone (PCL) homopolymer for use in medical procedures including orthopedic casting or splinting. The material is made from a thermoplastic composite that softens when heated to approximately 60° C., after which it can be formed directly on the patient. The composite then retains its shape as it cools down. The material is composed of epsilon caprolactone homopolymer reinforced with discontinuous short length wood particles.
摘要:
Aerated composite materials in the shape of a three-dimensional objects and methods of producing the same. The composite comprises a thermoplastic biodegradable polyester mixed with reinforcing agents selected from particles of woody materials having a smallest dimension greater than 0.1 mm. The composite material further comprises regions of elasticity formed by incisions which upon stretching will yield open pores. The incised regions will also provide for flexibility or semi-rigidity in at least one dimension. The material can be used in comfortable splints and circumferential casts.
摘要:
Novel composite materials, methods of producing the same and uses thereof. The composite materials which have the shape of three-dimensional object comprise a first component formed by a thermoplastic polymer selected from the group of biodegradable polyesters and mixtures thereof, and a second component formed by particles of a woody material, having a smallest dimension greater than 0.1 mm which reinforce the polyester. The material also has regions of elasticity or softness to provide for objects having properties of flexibility or semi-rigidity in at least one dimension. The material semi-rigid materials can be molded and worked at temperatures below 70° C. and are suitable for splints and circumferential casts.
