Abstract

Organic modification can generally endow inorganic materials with novel and promotional characteristics to fit into new functionalities. In this paper, new cement-based composite materials, with Portland cement as the substrate and polyacrylamide (PAM, alone) and PAM/chitosan as the functional components mixed with cement (bulk modified) or served as the surface coating (surface modified), were prepared and engineered as sampling substrates for biofilm and coral co-culture. In comparison to the bulk modified substrate and pure cement material, the surface modified substrate showed a balanced mechanical property, considering both bending and compressive strengths and distinctive surface features toward facilitating biofilm and coral growth, as characterized by spectroscopic, morphological, mechanical, and biofilm and coral co-culture experiments. We, thus, believe that the as-prepared surface modified substrate has the very potential to be applied as a substitute/alternative for the conventional cement material in the construction and engineering of artificial facilities with ecological protection functions.

有机改性水泥作为生物相容性基质与海洋模式生物界面的现象学研究。
有机改性通常可以赋予无机材料新颖和促进性的特性,使其具有新的功能。本文制备了新型水泥基复合材料,以硅酸盐水泥为基材,聚丙烯酰胺(PAM,单独使用)和聚丙烯酰胺/壳聚糖为功能成分,与水泥混合(块状改性)或作为表面涂层(表面改性),作为生物膜和珊瑚共培养的取样基材。通过光谱、形态、力学以及生物膜和珊瑚共培养实验,与块状改性基底和纯水泥材料相比,表面改性基底具有均衡的力学性能,既考虑了抗弯强度和抗压强度,又具有独特的表面特征,有利于生物膜和珊瑚的生长。因此,我们认为,制备的表面改性基材非常有潜力在具有生态保护功能的人工设施的建设和工程中用作传统水泥材料的替代品。

期刊介绍: Biointerphases emphasizes quantitative characterization of biomaterials and biological interfaces. As an interdisciplinary journal, a strong foundation of chemistry, physics, biology, engineering, theory, and/or modelling is incorporated into originated articles, reviews, and opinionated essays. In addition to regular submissions, the journal regularly features In Focus sections, targeted on specific topics and edited by experts in the field. Biointerphases is an international journal with excellence in scientific peer-review. Biointerphases is indexed in PubMed and the Science Citation Index (Clarivate Analytics). Accepted papers appear online immediately after proof processing and are uploaded to key citation sources daily. The journal is based on a mixed subscription and open-access model: Typically, authors can publish without any page charges but if the authors wish to publish open access, they can do so for a modest fee. Topics include: bio-surface modification nano-bio interface protein-surface interactions cell-surface interactions in vivo and in vitro systems biofilms / biofouling biosensors / biodiagnostics bio on a chip coatings interface spectroscopy biotribology / biorheology molecular recognition ambient diagnostic methods interface modelling adhesion phenomena.
