Abstract
Disclosed is a biodegradable sheet comprising at least one layer which comprises a biodegradable polymer and surface treated nanoclay particles or at least one layer which comprises PVOH grafted with a crosslinker and PBS or PBSA or a combination a biodegradable polymer and surface treated nanoclay particles and at least one layer which comprises PVOH grafted with a crosslinker and PBS or PBSA.
Claims6
A multilayered biodegradable sheet, wherein at least one layer comprises at least one biodegradable polymer and surface treated nanoclay particles, comprising a bridge between the surface treated nanoclay particles and the biodegradable polymer, said bridge comprising a functional moiety having at least two functional sites, wherein at least one of the functional sites is conjugated to the nanoclay particle surface and at least another one of the functional sites is conjugated to the biodegradable polymer;
- and the nanoclay particles are optionally homogeneously dispersed in the at least one layer.
