“…374 Hydrophilic monomers such as N-vinylpyrrolidone (NVP) can be copolymerized with silicon macromers to form hydrophilic silicone hydrogels. 375 Hydrophilic polymer segments such as PEG 376 can also be copolymerized onto silicone segments to form block-modified 377,378 or graft-modified 379 hydrophilic silicone hydrogels. Since these hydrophilic silicone hydrogels usually have excellent gas permeability as well good biocompatibility, they have been used in biomedical applications such as contact lenses, 14,380 histological engineering materials, 381,382 and drug-delivery carriers.…”

“…In order to form silicone hydrogels, hydrophilic monomers and/or polymers have been introduced into the silicone matrix by blending or copolymerization to improve the hydrophilicity of silicone hydrogels. ,, For example, hydrophilic polymers such as PHEMA can be blended directly into the silicone polymer matrix, forming a hydrophilic interpenetrating polymer network . Hydrophilic monomers such as N -vinylpyrrolidone (NVP) can be copolymerized with silicon macromers to form hydrophilic silicone hydrogels . Hydrophilic polymer segments such as PEG can also be copolymerized onto silicone segments to form block-modified , or graft-modified hydrophilic silicone hydrogels.…”

Hydrogels are polymer networks infiltrated with water. Many biological hydrogels in animal bodies such as muscles, heart valves, cartilages, and tendons possess extreme mechanical properties including being extremely tough, strong, resilient, adhesive, and fatigue-resistant. These mechanical properties are also critical for hydrogels' diverse applications ranging from drug delivery, tissue engineering, medical implants, wound dressings, and contact lenses to sensors, actuators, electronic devices, optical devices, batteries, water harvesters, and soft robots. Whereas numerous hydrogels have been developed over the last few decades, a set of general principles that can rationally guide the design of hydrogels using different materials and fabrication methods for various applications remain a central need in the field of soft materials. This review is aimed at synergistically reporting: (i) general design principles for hydrogels to achieve extreme mechanical and physical properties, (ii) implementation strategies for the design principles using unconventional polymer networks, and (iii) future directions for the orthogonal design of hydrogels to achieve multiple combined mechanical, physical, chemical, and biological properties. Because these design principles and implementation strategies are based on generic polymer networks, they are also applicable to other soft materials including elastomers and organogels. Overall, the review will not only provide comprehensive and systematic guidelines on the rational design of soft materials, but also provoke interdisciplinary discussions on a fundamental question: why does nature select soft materials with unconventional polymer networks to constitute the major parts of animal bodies?

“…Silicone-acrylic block, segmented and graft copolymers and interpenetrating networks have also been extensively investigated . In addition to basic studies on the composition dependent structure-morphology-surface behavior (270,274,276,281,282,284,285,290), these materials were also investigated as protective coatings (271,279,287), adhesives (273,277,283), membranes (286,288,289)and biomaterials (268,272).…”

A comprehensive survey of the recent developments on the synthesis, properties and applications of silicone containing copolymers is provided. Influence of (−R 2 Si−O−) backbone composition on the physicochemical properties of silicone copolymers, such as thermal transitions, solubility parameter and surface tension is discussed. Preparation and properties of well-defined α,ω-reactive organofunctionally terminated (telechelic) silicone oligomers and their utilization in the preparation of a wide range of block and segmented copolymers through step-growth,anionic, ring-opening and living free-radicalpolymerization techniques are provided. Use of silicone oligomers in the modification of polymeric network structures is also discussed. Special emphasis is given to the discussion of the effect of silicone oligomer and organic segment structure and molecular weight on the morphology and surface and bulk properties of the resultant silicone containing copolymers and networks.

“…The systematic study of the compositionally asymmetrical morphology of APCNs is of major importance, when a stable, bicontinuous nanophase-separated structure is formed over a broad composition window of both constituent phases with large inner surface between the distinct phases. This kind of morphology is favourable in a variety of elds such as ion conduction, 33 oxygen permeation, 34,35 tissue engineering 36 as well as support for enhanced enzyme catalysis 18,19,37 or nanotemplates of nanohybrid materials. 27 In our previous publications, the synthesis and some fundamental structure-property correlations of poly(N-vinylimidazole) (PVIm) based conetworks were investigated.…”
