RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
Radiation-curing by polymerization of multifunctional monomers is a well-established technology in the field of coatings and adhesives as well as in the graphic arts. UV-visible light and high energy radiation are alternative activation processes exhibiting their specific scope, advantages, and limitations depending on the application. The situation is quite different when the industrial goal...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
There is a need to develop active packaging and active edible coating by using natural ingredients. To reduce the pollution problems caused by synthetic and non-biodegradable packaging films, biodegradable packaging materials are encouraged to be developed especially in case of antimicrobial packaging. Also, the consumer demand to replace synthetic antimicrobial by natural compounds is rising....

Low density polyethylene (LDPE) film was grafted with sorbic acid (SA) using radiation induced grafting (RIG) technique to develop advanced antimicrobial grafted film for active packaging application. Instead of mixing antimicrobial additive as food additive directly with food, this additive was incorporated in films via RIG and allow the functional effect at the food surface, whereby the...

Abstract:
The effect of ionizing radiations on the cross-linking and degradation
of some natural polymers such as CMC-Na, chitosan, carrageenan,
alginates and starch was investigated. Trials were made to...
