Electroactive polymers

Two of their main characteristics allows a major advantage over non-biodegradable delivery systems. Biodegradability is an important first characteristic of the polymer, and thus not required to remove it. The second one being the release rate more regular and less dependent on the intrinsic property of the polymer used. Commercially, Poly lactic acid as a polymeric carrier is the choice on account of their harmlessness to the human body. As cognized, the smaller particles give rise to

The University of Nottingham, Malaysia Campus Faculty of Engineering Department of Mechanical, Materials and Manufacturing Engineering MM3BPR Progress Report PROJECT TITLE : STUDY OF BLOOMING IN BIO-FILLER REINFORCED RUBBERS NAME : SYED TAQEE NAWAZ STUDENT ID : 011471 SESSION : 2014/2015 SUPERVISOR : DR AI BAO CHAO MODULE CONVENOR : DR CHRISTINA CHIN SUMMARY This project is aimed at developing a systematic approach to analyse the phenomenon of blooming

mechanical, thermal and optical qualities of the material: 1. The organic polymers influence the polarity, the ability to cross link, hardness and optical behaviour. 2. The glass and ceramic components (inorganic constituents) are responsible for thermal expansion and chemical stability. 3. The polysiloxanes influence the elasticity, interface properties and processing. 4. The inorganic components are bound to the organic polymers by multifunctional silane molecules. After polymerisation the organic

Experiment 1: Release of Aspirin from a Polymer Matrix Summary Firstly, aspirin was weigh to 0.25g which was then dissolved in 100cm3 of distilled water by heating to >80°C using a hotplate. 2.0g of agar was added while stirring and was heated till dispersed, giving almost clear solution. The temperature was control so as not to overheat the agar. The agar was left to cool in an ice bath. Using a hollow cylinder, the agar was cut to approximately 4.0g (the exact weight of the agar was recorded).

sustain drug/gene effect in target tissue, to solubilize drugs for intravascular delivery, and to improve the stability of therapeutic agents against enzymatic degradation, especially of protein, peptide, and nucleic acids drugs [1]. By tailoring polymer qualities, on can specify design factors that can control the release of therapeutic agents to provide excellent targeting for optimal efficacy. The ability to theses distant destinations, nanoparticles are led by bio specific ligand which could direct

soon became manufactured. Kevlar soon became used in body armor all over the world and is still seen being used today. Kevlar is constructed of manmade fibers known as aramids. It belongs to a class of polymers. The polymers work just like gauze, but at a microscopic level. The basic unit of a polymer is a chain. Each one of the chains is made of millions of “monomers” that are linked to each other by chemical bonds. The monomers are long and rod-like. With Kevlar, the monomers link with there own

In the 1962, Bowen first developed the BIS-GMA monomer which was first chemically cured to form chains of polymers. The chemically cured composite was a base pasted mixed with a catalyst which resulted in problems of proportions and colour stability. In 1970’s, light cured composites were introduced. UV light (365nm) was first used but was found to have shallow polymerisation hence was later replaced by blue visible light (427-491nm). Composite resins developed in the 1970’s contain large filler

Eudragit RS and RL 100 polymers have been selected as a carrier for fabrication of nanofibers due to their nice stability, biocompatibility, and nice adhesion over skin due to excellent swelling property, and presence of surface charge. These charges can facilitate prolonged residence time and adhesion over targeted site (Haznedar et al, 2004). Their combination customize drug release, moreover presence of quaternary ammonium compound further check reoccurrence of microbial infection. Chemically

Develop 3D printable natural and synthetic polymer systems, for biological scaffolds, that are tough enough to produce highly complex parts with small internal features and porosity to allow for microvascular regrowth to attach onto the scaffolds. To obtain a scaffold with suitable mechanical and viscoelastic properties (Young’s modulus 0.35± .11 MPa, Tensile stiffness 8.59±3.5 MPa, Equil. Modulus 13.6±1.5 MPa), it is very important to choose the proper polymeric material and fabrication technique10
