   Sammanfattning : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. LÄS MER

3. 2. Investigation of graphene and nanocellulose hybrid films as a barrier material in packages

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Sammanfattning : In this report, hybrid films of carboxymethylated cellulose nanofibrils (CNF) and graphene nanosheets (GNs) have been prepared to evaluate if the GNs can enhance the barrier properties of the CNF films. CNF already possess great barrier properties at low relative humidity (RH) but it is drastically lowered when the RH reaches above 50% due to its strong hydrophilicity of CNF. LÄS MER
