Polydimethylsiloxane mechanical properties: A systematic review

Abstract

<abstract> <p>Polydimethylsiloxane (PDMS) has been a promising material for microfluidic, particularly in lab-on-chip. Due to the panoply of good physical, mechanical and chemical properties, namely, viscosity, modulus of elasticity, colour, thermal conductivity, thermal coefficient of expansion, its application has been increasingly requested in quite different areas. Despite such characteristics, there are also some drawbacks associated, and to overcome them, several strategies have been developed to modify PDMS. Given the great variety of relevant conducted research in this field, the present work aims to gather the most relevant information, the advantages and disadvantages of some of the techniques used, and also identify potential gaps and challenges in it. To this end, a systematic literature review was conducted by collecting data from four different databases, Science Direct, American Chemical Society, Scopus, and Springer. Two authors independently screened the references, extracted the key information, and assessed the quality of the included studies. After the analysis of the collected data, 25 studies were selected that addressed the various mechanical properties of PDMS and how to modify them in order to suit a particular application.</p> </abstract>

Mechanical and thermal properties of polydimethylsiloxane/magnetite nanocomposites for cancer treatment by localized hyperthermia and photothermal ablation

“…The fracture toughness values of the composites were calculated at the peak loads using Equations ( 9) and (10). The fracture toughness values obtained for each specimen are summarized in Table 2 and Figure 4a.…”

“…It also exhibits attractive combinations of elastic/ viscoelastic properties, optical transparency 8 and, biocompatibility, high gas permeability, high compressibility, chemically inertia, high flexibility; and chemical/thermal stability. 9,10 PDMS can also be mixed with different reinforcements to produce composites with engineered combinations of mechanical, magnetic, plasmonic, and thermal properties. [10][11][12] Such combinations of properties, along with the biocompatibility of the PDMS matrix, make PDMS composites attractive for applications in biomedical devices.…”

Low-Cost Multifunctional Vacuum Chamber for Manufacturing PDMS Based Composites

“…Elastomers have become popularly known in several scientific areas in recent decades due to their excellent characteristics and properties, such as: flexibility, biocompatibility and corrosion resistance [1]. PDMS is, among the various existing elastomers one that has been receiving attention among researchers at different engineering fields [2,3]. PDMS is a mixture of linear polymers belonging to a group of silicones based on organic polymers.…”
