Blends biodegradable

Biodegradability has been explored in agriculture to prevent excessive moisture loss and weeds growth, and to alleviate the recyclability problems — an agricultural film should last as long as it is needed, then disintegrate under the influence of either microorganisms and/or UV irradiation. [Pg.93]

The biodegradable polymer blends are often prepared by blending a thermoplastic resin with a biodegradable one (see Table 1.80). Blending must produce dispersion that after disintegration of the biodegradable part the thermoplastic powder will not contaminate the environment. [Pg.93]

Plasticized starch has widely been studied in a mixture with other polymers [AVE 04a, AVE 00a, AVE 00b, AVE 01a, MAR 01a, MAR 01b, SCH 04]. A large nrrmber of patents have been pubUshed on this subject [AVE 04a]. These research efforts have led to the commercialization of different biodegradable blends - some of them based on plasticized starch (Table 9.4). [Pg.180]

Numerous non-biodegradable blends with synthetic polymers [ARV 99, STP 97], such as polyolefins, have been commercialized. As is currently the case for oxo-degradable polymers, these blends have, in the past, caused great controversy, because they were falsely presented as being biodegradable. Sometimes, the term biofragmentable was apphed to these substances. [Pg.182]

Abstract Biopolymers are expected to be an alternative for conventional plastics due to the limited resources and soaring petroleum price which will restrict the use of petroleum based plastics in the near future. PLA has attracted the attention of polymer scientist recently as a potential biopolymer to substitute the conventional petroleum based plastics. The chapter aims to highlight on the recent developments in preparation and characterization of PLA blends (biodegradable and non-biodegradable blends), PLA composites (natural fiber and mineral fillers) and PLA nanocomposites (PLA/montmorillonite, PLA/carbon nanotubes and PLA/cellulose nano whiskers).

Starch is used today in a large number of products with very diverse properties. The roles played by starch include load bearing polymeric material, a component of biodegradable blends, a filler in biodegradable materials, and even a role of plasticizer. Its popularity stems from a low price, being derived from a renewable source, being familiar component fonnd in the natural environment and as such easily convertible by natural means, chemically reactive, and compatible with many materials.
