Case Study

Composite Hydrogel Based on Tantalum Carbide Nanoparticles as Cell Adhesion Material

Hu X, et al. International journal of biological macromolecules, 2019, 135, 501-511.

A polymeric composite hydrogel composed of salecan/poly(diacetone acrylamide) (PDAAm) network and tantalum carbide (TaC) nanoparticles was developed. In this composite hydrogel, the embedded TaC nanoparticles not only provide physical anchoring and mechanical reinforcement but also significantly improving the compressive modulus, storage modulus, and thermal stability.
Synthesis procedure of Salecan/PDAAm/TaC composite hydrogel
· A series of salecan/PDAAm/TaC composite hydrogels were synthesized through microwave-assisted polymerization, utilizing TEGDMA as a crosslinker.
· Specifically, a specified amount of salecan solution (2%, w/v), 1 mL of DAAm solution (30%, w/v), and 1 mL of TEGDMA solution (3%, w/v) were combined in a cylindrical mold.
· Subsequently, a certain quantity of TaC nanoparticles dispersion (5%, w/v) was introduced into the mixture with vigorous stirring for 1 hour at 0 ºC in an ice-water bath. The total volume was adjusted to 10 mL with deionized water (DW). An addition of 1 mL of APS solution (6%, w/v) was made with vigorous stirring in an Ar atmosphere.
· The mold was then exposed to a household microwave oven at 500 W for 5 minutes. The resultant composite hydrogels were then cut into small pieces and soaked in deionized water for 4 days to remove any unreacted components. It is important to replace the deionized water three times daily.

Preparation Strategy of Tantalum Carbide Nanoparticles Decorated Carbon Spheres

Bhattacharjee K, et al. CrystEngComm, 2016, 18(8), 1427-1438.

Highly dispersed tantalum carbide nanoparticles (TaC NPs) were successfully decorated on carbon spheres (CS) using a unique carbothermal reduction method. The diameter of the TaC NPs decorated CS (CS@TaC) composite spheres is about 0.8-1 μm, and the average size of the surface TaC NPs is 41 nm.
Preparation of CS@TaC composite
· 100 mg of hydrothermally prepared CS were dispersed in 5 ml of distilled water using ultrasonication.
· Following this, 5 mL of C3H8O was introduced to the beaker and the mixture was stirred for 1 hour. Simultaneously, C3H8O and C5H8O2 were combined in a 1:1 volume ratio in a separate beaker, followed by the addition of 2.14 mL of [Ta-(OCH2CH3)5] with continuous stirring for 1 hour.
· Subsequently, the dispersed CS were incorporated into the previous beaker and subjected to additional stirring for 5 hours at 50 °C. The mixture was then washed multiple times with water and ethanol before being left to dry in an oven at 60°C for 2 days.
· The dried sample was then placed in a charcoal boat with a charcoal lid and inserted into a tube furnace with a constant flow of ultrapure argon. The sample was heated to varying temperatures ranging from 1100 °C to 1350 °C for 30 minutes under the argon atmosphere. After cooling to room temperature, the resulting black residue was collected.
