摘要

表面黏附是生产生活中的常见现象，对设施设备的可靠运行产生诸多不利影响. 以润滑剂为溶剂的有机凝胶凭借其独特的三维网络结构和表面自润滑特性，在抗黏附领域展现出显著优势. 本工作通过将低玻璃化转变温度(

)的疏硅油聚甲基丙烯酸月桂酯(PLMA)链段与高

亲硅油的聚甲基丙烯酸叔丁酯(PTBMA)共聚，制备了一种高强韧低回滞的自润滑有机凝胶. 疏硅油PLMA链段可诱导有机凝胶形成连续相分离结构，并与网络本征的高柔性协同赋予凝胶优异的机械性能与自恢复能力. 甲基丙烯酸叔丁酯/甲基丙烯酸月桂酯(TBMA/LMA)摩尔比为1/3的PT

自润滑有机凝胶展现出最佳性能，其拉伸强度、断裂伸长率和杨氏模量分别高达0.35 MPa、7

98%和0.32 MPa. 在静息3 min的加载—卸载循环测试中，该有机凝胶的自恢复率可达94.6%. 自润滑有机凝胶表面的液滴滑动角低于7°，冰黏附强度低于20 kPa，对牛血清白蛋白(BSA)和大肠杆菌(

E. coli

)的黏附量分别降低了76.6%和90%，在自清洁与抗黏附领域展现出广阔的应用前景.

Abstract

Surface adhesion is a common phenomenon in both industrial production and daily life

often adversely affects the reliable operation of facilities and equipment. Organogels that utilize lubricants as solvents have demonstrated distinctive advantages in anti-adhesion

owing to their unique three-dimensional network structure and surface self-lubricating properties. In this work

a low-hysteresis and high-toughness self-lubricating organogel was prepared by copolymerizing the silicone-phobic poly(lauryl methacrylate) (PLMA) segments with low glass transition temperature (

) and silicone-philic poly(

tert

-butyl methacrylate) (PTBMA) with high

. The resulting continuous phase-separated structure

combined with the high flexibility of the network

synergistically endowed the self-lubricating organogels with excel

lent mechanical properties and self-recovery capability. Specifically

the PT

self-lubricating organogels with the TBMA/LMA molar ratio of 1/3 exhibited fracture stress of 0.35 MPa

fracture strain of 798%

and Young's modulus of 0.32 MPa. After a 3-min waiting period

the organogels achieved a self-recovery rate of 94.6% in loading-unloading cycles. Furthermore

droplets slide off the surface at a sliding angle of ≤7°

while bovine serum albumin (BSA) and

Escherichia coli

(

E. coli

) adhesion were reduced by 76.6% and 90%

respectively. The ice adhesion strength was as low as 20 kPa. These results indicate that the organogels hold great potential for anti-adhesion and self-cleaning applications.
