Cyanoacrylates are widely used as surgical tissue adhesives because of their high biodegradability, but they are brittle and have poor tissue affinity. In this study, methoxy polyethylene glycol‐polycaprolactone block copolymers (MPEG‐co‐PCLs) with different PCL chain lengths were synthesized by ring‐opening polymerization. Then, a new tissue adhesive with excellent mechanical properties, tissue affinity, antibacterial properties, and coagulation performances was prepared by incorporating MPEG‐co‐PCL and silica nanoparticles (SNPs) into n‐butyl cyanoacrylate (BCA). The optimal MPEG: PCL ratio is 1:4 (MP‐3), and the optimal mass ratio of MPEG‐co‐PCL and SNPs (0.5SNPs/0.5MP‐3) is 0.5 wt.%. Compared to BCA, the adhesion strength and flexibility of 0.5SNPs/0.5MP‐3 are dramatically improved by 110% and 244%, respectively. MPEG‐co‐PCL can fully exploit the advantages of homopolymers, and therefore, improve the tissue affinity and adhesion strength of the adhesive and avoid BCA polymerization initiated by MPEG and poor compatibility of PCL with BCA. SNPs can also compensate for the lack of antibacterial properties of BCA against Gram‐negative bacteria. The E. coli inhibition circle of 0.5SNPs/0.5MP‐3 is twice as large as BCA. SNPs can also improve coagulation by promoting platelet aggregation. This work provides an effective strategy for developing adhesives with potential clinical applications.

“…The detailed information about the principle was reported by Ghatee et al in literatures. 6,7 The pressure vessel was installed in the thermostatic bath whose temperature was stable within 10 mK for at least 2 h. Ethyl alcohol, water, and silicone oil were used as the thermostatic fluids in the temperature range of 240−280 K, The height difference in two capillary was determined by a special designed camera and image processing technique with an uncertainty of 0.012 mm. The image acquired from the camera monitor panel is shown in Figure 2, which can be used to analyze the difference rise height.…”

An experimental apparatus based on the differential capillary rise method for measuring the surface tension was built up and verified. The surface tensions of R1234yf and R1234ze(E) were measured from 242 to 365 K and 242 to 380 K, respectively. The surface tension data were correlated as a function of temperature, and the average absolute deviations between the experimental and calculated values were 0.002 mN·m–1 for R1234yf, and 0.009 mN·m–1 for R1234ze(E). The surface tension data at temperature lower than 273 K was first reported.
