|Title:||Degradation studies of a tracheal stent||Authors:||Vadlamani Lalitha Deepika||Keywords:||DRNTU::Engineering||Issue Date:||2009||Abstract:||The major objective of this project is to examine the viability of biodegradable polymers as tracheal stents, for the treatment of tracheal obstruction.In this report, the degradation profiles of PLLA-PCL copolymer with 10% glycerol, TEC and PEG were observed. The 3 films of 0.5mm thickness approximately, required for the study were made and cut to the dimensions of 1 by 1 cm. These squares were then immersed in 100% deionised water and incubated at 370C for a period of 14 weeks. A layer by layer (50 μm) analysis of the 1 by 1 squares was carried out using a microtome and the subsequent characterisation of the weighted average molecular weight of the films was done using gel permeation chromatography (GPC).||URI:||http://hdl.handle.net/10356/15423||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
