The first part of this paper summarizes relevant literature information, whic. rationalizes our selec.ion of c.emic.ls. The sec.nd part reports some preliminary sc.eening results. We have investigated a wide range of reagents, c.osen for their different c.emistries and divided into seven c.asses: (1) reduc.ng agents, (2) reduc.d sulfur c.mpounds, (3) hydrogen donors, (4) antioxidants and radic.l sc.vengers, (5) nuc.eophiles, (6) c.elating agents, and (7) oxidizing bleac.ing agents. It is noted that some c.emic.l reagents fall into more than one c.ass. The obtained results will be disc.ssed with respec. to the effec.iveness of eac. c.ass.

For room temperature self-healing triboelec.ric.nanogenerators（TENGs）, the inherent c.ntradic.ion between mec.anic.l strength and self-healing properties was an urgent problem to be solved. Based on the phenol-c.rbamate bond, this paper proposed a strategy to design a new molec.lar struc.ure and c.ordinate the triple dynamic.bonds, whic. provided a feasible strategy to solve this c.ntradic.ion. With polytetramethylene ether glyc.l（M_n= 1,000） as the soft segment in the main c.ain of polyurethane（PU）, meanwhile methylene diphenyl diisoc.anate and 4,4′-dihydroxybiphenyl（BP） as the hard segment and c.ain extension agent, respec.ively, the c.mbination of tetrad benzene ring endowed the resultant 4BP-PU with π-π interac.ion. The effec.ive reversible dissoc.ation and assoc.ation with hydrogen bond not only bestowed 4BP-PU with high mec.anic.l strength（16.14 MPa）, but also promoted high self-healing effic.enc.（94.8%） at room temperature. 4BP-PU was selec.ed as the elastic.substrate between polydimethylsiloxane and c.pper sheet to prepare a self-healing TENG to c.llec. energy from natural ***, the rational molec.lar struc.ure design provided new ideas for developing self-healing materials and fabric.ting energy harvest elec.ronic..
