- Abstract:
- ... Excellent comprehensive dielectric properties (including dielectric constant and loss) are essential for electromechanical transducers. This work introduced a bimodal network composite with poly(dimethyl siloxane) (PDMS) and delaminated Ti₃C₂Tₓ sheets (d-Ti₃C₂Tₓ) modified with hyperbranched polysiloxane (HPSi) (referred to as HPSi-d-Ti₃C₂Tₓ). Before the final cross-linking, HPSi-d-Ti₃C₂Tₓ, trapped ...

A convenient method for the selective synthesis of alkoxyhydrosiloxanes that bear SiH and SiOR² groups on the same silicon atom, R¹₃Si–O–SiR³₂₋ₙ(OR²)ₙH (n = 0, 1, or 2), via a simple catalyst- and additive-free dealcoholization reaction between silanols and alkoxyhydrosilanes has been developed. These alkoxyhydrosiloxanes can be easily converted into Si(OR²)₃-containing siloxanes by zinc catalyzed ...

- Abstract:
- ... Nacre-like polymer/clay nanocomposites are a fascinating material thanks to its superior mechanical property. However, it has been a great challenge to incorporate hydrophobic polymer components due to highly hydrophilic nature of clay, which limits further improvement of water-resistance and addition of various functionalities. To overcome this problem, we developed a method to form regular nacre ...

The current work demonstrates broad gradient-transition multiphase separation for thermoplastic polysiloxane-based polymers, featuring mechanical robustness, shape memory property and healing-ability. Conventional thermoplastic elastomers are generally fabricated by embedding hard nanodomains as physical crosslinks into a soft matrix. However, it is difficult to achieve shape-memory capability in ...

The biodegradation of H₂S in the BTF followed a first-order kinetic model and more than 95 % H₂S was eliminated within a residence time of 0.3 min. The removal of decamethylcyclopentasiloxane (D5) increased with longer empty bed residence time (EBRT). The partition t ...
