@BapanPramanik2 @EelkemaLab @syschem20 Hi Bapan, Thanks! Research about self-healing hydrogel has been published on ACS Macro Letter: https://t.co/2vcpLxwstD.

[Bowen Fan @Chembowen]

Happy to share my PhD work on fuel-driven transient hydrogel from @EelkemaLab in this virtual conference @syschem20. Your comments and questions are always welcome. #syschemposter

@Lasith_S_K @EelkemaLab @syschem20 3-2. I didn't test DTBA. Thanks for your suggestion. I will consider it. :)

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @syschem20 3-1. I tested DTT in place of TCEP. DTT can also work in my system but the ratio and amount of DTT to alkyne have to be controlled very carefully. Otherwise the sidereaction beween DTT and alkyne will also happen.

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @syschem20 2. Oxidation of TCEP with H2O2 is not negligible. Besides, side reactions between TCEP and alkene or alkyne will also influence the prograss of cycle. I have to control the ratio and amount of TCEP and H2O2 very carefully.

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @syschem20 1-2 BME prefers to react with alkyne and alkene and TCEP prefers to react with disulfide but not air. So the oxidations by air are negligible in my system.

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @syschem20 Thanks for your questions. They are quite important points for my research.
1-1. Yes, I noticed them. In basic condition, mercaptoethanol (BME) and TCEP are easy to be oxidized by air. However, there are some competitions in my system.

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @syschem20 Thanks for your nice question! I didn't use any exogenous base. The thiol was deprotonated only by basic buffer (Phosphate Buffer, pH=8.2).

[Bowen Fan @Chembowen]

@Lasith_S_K @EelkemaLab @ACSMacroLett @ERC_Research We purchased this 4-arm PEG thiol polymer from JenKem Technology (USA). 10 g is $800.
