A Review of Polysiloxanes in Terms of Their Application in Explosives

Abstract

Polysiloxanes are reviewed for their properties depending on the functionalization of a silicon–oxygen backbone chain. Next, the properties were referred to the requirements that polymers used in plastic/polymer-bonded explosive (PBX)-type explosives must meet. Finally, the current state and prospects for the implementation of polysiloxanes in plastic/polymer-bonded explosive (PBX) formulations are presented.

Siloxane Matrix Molecular Weight Influences the Properties of Nanocomposites Based on Metal Complexes and Dielectric Elastomer

“…From this approach, the present work is focused on the changes of properties important for dielectric elastomers of polydimethylsiloxane polymers with multiple molecular weights and two types of dielectric constant-enhancing fillers. This study furthers previous work on the influence of the molecular weight of silicones on the properties of materials such as phase separation morphology, oxygen permeability, and mechanical properties [ 25 ]; transparency and mechanical properties of silicone block copolymers [ 26 ]; and as a matrix for explosives [ 27 ]; with a focus on mechanical and dielectric properties, which for dielectric siloxanes are important not only for electric circuits and cables but also for actuators and energy harvesting devices built with silicone dielectric elastomers [ 8 ]. The fillers used for the dielectric elastomers are distinct from materials used as fillers by other researchers due to presence of the organosiloxane chain in the complex that provides compatibility with the silicone matrix.…”

Ring-Opening Polymerization (ROP) and Catalytic Rearrangement as a Way to Obtain Siloxane Mono- and Telechelics, as Well as Well-Organized Branching Centers: History and Prospects

“…The nature of the backbone determines the set of unique characteristics of these macromolecular compounds, making them indispensable in the creation of materials widely used in various fields of practice, ranging from construction, engineering, agriculture, and environmental protection to medicine, cosmetics, pharmaceuticals, and home care products [1][2][3][4][5]. Siloxanes have low surface tension, hydrophobicity, good surface wettability, damping properties, low glass transition temperature and frost resistance, low temperature dependence of physical properties, low toxicity and flammability, and they are safe for the environment [6][7][8]. The most important property of siloxanes is biocompatibility, which are already actively used in science and technology [9].…”

“…The most important property of siloxanes is biocompatibility, which are already actively used in science and technology [9]. The development of new high-tech industries, such as organic electronics and photonics, 3D printing, gas separation, and drug delivery, has led to a further expansion of the applications for various types of organosiloxane polymers [8][9][10][11][12][13][14].…”

Simple Preparation of Polydimethylsiloxane and Polyurethane Blend Film for Marine Antibiofouling Application

“…Polydimethylsiloxane (PDMS) is widely used for antifouling coating because it consists of -Si-O-Si-and a side chain of the -CH 3 group, leading to good thermal stability, elasticity, and hydrophobicity [11]. The polymer main chain of siloxane bonds (-Si-O-Si-) has a high bond energy and bond angle that provide good thermal stability and elasticity for PDMS [12].…”
