  • Why should you choose wholesale polyacrylamide & chemical products supplies?
  • Wholesale polyacrylamide and chemical products supplies from our company are high-quality and affordable. You will enjoy our quick responses from our sales team whether it is wholesale, pre-sales, post-sales or something in between; We are at your disposal all the time.
  • What is Acrylated peg in polyacrylamide hydrogel?
  • Incorporating acrylated POSS-PEG into polyacrylamide hydrogel yields enhanced properties such as toughness of up to 6531 kJ m −3 and break elongation up to 9455%, where the length of PEG chains grafted onto POSS is demonstrated to play a crucial role in facilitating energy dissipation and achieving high toughness.
  • How is polyacrylamide hydrogel precursor prepared?
  • Polyacrylamide (PAM) hydrogel precursor was prepared as follows: A specified amount of cross-linker was dissolved in deionized water by ultrasonic treatment first. Subsequently, acrylamide monomer and LAP were added to the dispersion and sonicated for a few minutes to disperse the components evenly.
  • What are the advantages of PDA/CNT/Pam hydrogels?
  • The large number of hydrogen bonding and π-π stacking derived from the PDA ensure the self-healing and self-adhesive efficiencies of the PDA@CNT/PAM hydrogels, while the presence of the conductive CNTs enhances the electronic transmission capacity and mechanical properties of the hydrogels.
