Anisotropic mesoporous silica/microgel core–shell responsive particles

Abstract

<p>Hybrid anisotropic microgels with different morphologies were prepared using mesoporous silica particles as core and PNIPAM as shell. The shell thickness <italic>d</italic> and aspect ratio <italic>ρ</italic> were characterised notably <italic>via</italic> cryo-TEM (left) and DLS (right).</p>

Stiffness Tomography of Ultra‐Soft Nanogels by Atomic Force Microscopy

“…[30] Recent progress in synthesis enabled preparation nanogels with internal compartments and various shapes. [31][32][33][34][35] Furthermore,i sw as observed that the extreme softness of ultra-low cross-linked (ULC) nanogels leads to unique properties. [36] ULC nanogels exhibit high swellability and flexibility.…”

Thermoresponsive Polymers for Water Treatment and Collection

“…For example, a microfluidic setup created Janus microgels comprised of PNIPAm but at two different contents (Figure C) . More advanced core–shell microgels with desired shapes have also been made with thermoresponsive and nonthermoresponsive compartments. , For example, PNIPAm/ethyl cellulose (EC) core–shell microgels (Figure C) were produced via a microfluidic setup to encapsulate vitamin B12 and improve its release at body temperature . In a more complex design, gold nanotriangles and nano-octahedra were embedded in PNIPAm microgels.…”

A Strategy to Develop Homo-polypropylene Composites with High Impact and High Rigidity

“…Up to now, core–shell rubber particles (CSRPs) have been widely used to toughen PP. − Using different core–shell structures to toughen PP has been studied extensively. For example, the core–shell structure of toughened PP can use PE as the core and EPR as the shell, , silicon dioxide-EPDM core–shell particles, and so on. − The addition of core–shell particles and the formation of a ternary blend system, according to the theoretical model proposed by Wu, can simultaneously improve the toughness and reduce the modulus loss in composite materials.…”
