  1. 1. Pharmaceutical Nanocomposites : Structure–Mobility–Functionality Relationships in the Amorphous State

    Author : Joel Hellrup; Denny Mahlin; Göran Alderborn; László Fábián; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; amorphous; pharmaceutical composites; solid state; structure; molecular mobility; spray-drying; freeze-drying; moisture sorption; physical stability; compression; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : Amorphous materials are found in pharmaceutical formulations both as excipients and active ingredients. Indeed, these formulations are becoming an essential strategy for incorporating drugs into well-performing solid dosage forms. READ MORE

  2. 2. Inorganic and organic polymer-grafted nanoparticles : their nanocomposites and characterization

    Author : Carmen Cobo Sanchez; Eva Malmström; Henrik Hillborg; Anna Barros Timmons; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Si-ATRP; ATRP; polyelectrolytes; rGO; aluminium oxide; silica; CNF; CNC; PCL; LDPE; EBA; nanocomposites; matrix-free; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. READ MORE

  3. 3. Protein-based packaging films, sheets and composites : process development and functional properties

    Author : Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites; Energi och material; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

    Abstract : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

  4. 4. Polymer Nanocomposites in Thin Film Applications

    Author : Linda Fogelström; Anders Hult; José M. Kenny; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Nanocomposites; hyperbranched polymers; montmorillonite; clay nanoparticles; exfoliated; coatings; crosslinking; TEM; XRD; mechanical properties; thermal properties; cellulose nanofibers; Atom Transfer Radical Polymerization; Ring-Opening Polymerization; poly ε-caprolactone ; surface modification; grafting; interfacial adhesion; Polymer chemistry; Polymerkemi;

    Abstract : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.
