  1. 1. Silicone biomaterials obtained by plasma treatment and subsequent surface hydrosilylation

    Författare :Björn Olander; KTH; []
    Nyckelord :Silicone elastomers; PDMS; XPS; ESCA; surface modification; plasma;

    Sammanfattning : The need for safe and functional implants has led to anincreased demand for improved biomaterials. The performance invivo depends on the interaction between the biologicalsurrounding and the surface of the material. LÄS MER

  3. 2. Crosslinking of Polymers. Molecular Structure and Properties of Sol and Network

    Författare :Helena Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDMS; long chain branchin; entanglement; crosslinking; contamination; network; bimodal; Silicone; polyethylene;

    Sammanfattning : Crosslinking is a well-known procedure for improving a variety of features of polymers, particularly the dimension stability at elevated temperatures. Crosslinking implies the formation of a network, the gel, but there is always a certain portion of the material, the sol, that remains non-crosslinked within the network. LÄS MER
