摘要：Nowadays, HDPE water pipe has been used in massive quantities, which brings many conveniences to human beings but also raises problem of susceptible to bacterial contamination. Thus, we described a simple and feasible way to design cost-efficient and antibacterial HDPE pipes with excellent mechanical properties. A basalt fiber (BF) and silver ion glass microbead (AgGB) were coupled by 3-aminopropyl triethoxysilane to form a compound antibacterial agent. Then, the obtained AgGB@BF was melt-mixed with HDPE to produce antibacterial composite. By means of BF surface modification, the AgGB dispersivity in HDPE matrix was obviously improved. The adding of AgGB@BF would simultaneously increase the thermal decomposition temperature and crystallinity of HDPE composites. And, the crystallinity of HDPE could reach the maximum value of 66.3% under a high-pressure condition. The mechanical strength of resultant HDPE composite increased from 17 to 25 MPa. Meanwhile, a long-term and excellent antibacterial property of the HDPE composite was obtained against Escherichia coli. The proposed antibacterial materials can provide a way for designing and preparing eco-friendly and high-performance HDPE pipe products.
