“…According to Roach et al, electrostatic repulsion can also influence the contact angle value, if roughness also exists as demonstrated in (Figure 2), surface forces are further influential in the superhydrophobic water contact angle. [21] In comparison, a 60% (v/v) polymeric PVC/ethanol solution has average pore sizes of 0.5-1 mm in diameter and at 80% (v/v) pore sizes were larger 5 mm, and less frequent.…”

“…PVC typically consists of 57% chlorine and 43% carbon, derived predominantly from oil and gas via ethylene. [11,21] Figure 1 demonstrates that PVC, without plasticizer incorporation can be modified to produce some unique surface properties, in this case, superhydrophobicity. [20] However, when plasticizers are introduced to modify the physical or mechanical properties of the polymer, the contact angle can increase or decrease depending on the plasticizer used.…”

“…The superhydrophobic PVC material outperformed other plasticized PVC materials by 34% for the biofilm adhesion assay using protein and carbohydrate adhesion. The filtration stage of the marine water in the sampling protocol has feasibly removed larger fouling organisms, however, the length of the study represents a study engineered to assess biofouling of the crucial "initial stages", [10,21] examining the point of difference in the initial colonization phase of each of the material's surfaces. [1] Therefore, the materials' demonstrate real promise in resisting microorganisms responsible for early stage biofouling in high-fouling activity waters.…”

Here we show an easy to synthesize superhydrophobic material using a solvent phase-separation process of poly vinyl chloride. It is found that solvents mixed in different ratios increase the dielectric value of the solvent and can be tuned to produce superhydrophobic PVC. The PVC solution is then spin-coated onto glass slides for characterization using scanning electron microscopy. Plasticizers are doped into the 70% (v/v) PVC to determine their overall effects; it is found that plasticizers reduce the water contact angle value. The final coatings were tested in a series of antifouling assays in a marine environment lab study; it is found that the superhydrophobic PVC material reduced marine biofouling.

“…Critically, the importance of being able to quantify baseline levels of the detachment phase during a biofilm cultivation experiment in order to study the actual effect of remediation or mitigation techniques (i.e., increased shear, biocidal agents [3,4,[14][15][16]) is extremely important. Previously, authors have demonstrated that detachment occurred only when the biofilm was fully formed-however, this is incorrect and detachment can occur at any time of the biofilm formation process.…”

The rheological properties of biofilms have a great impact on major processes such as transport of nutrients, light, biocides, water, biochemicals and cells. The knowledge of the mechanical properties of biofilms is essential in quantifying the overall process of biofilm development and bacterial survival (and proliferation)-one of the key processes in a biofilm lifecycle is detachment. It is therefore crucial to be able to predict the biofilm detachment and break up in response to internal and external forces that drive the biofilm cycle. This chapter aims to highlight some of the important processes in the biofilm detachment cycle. It will also draw on some new and old concepts on this age old battle of biofilm survival and proliferation.

“…In general, however, biofouling is likely to represent a practical limitation to the (maintenance-free) deployable lifetime of this sensor and similar systems. Therefore it is essential that developers of water monitoring technology are familiar with the range of established and emerging [36,37,[41][42][43][44] approaches to the prevention or limitation of biofouling, and work collaboratively with researchers engaged in this area, which is a key to achieving the long deployable lifetimes which will ultimately facilitate the broader uptake of in-situ sensing technologies.…”

Abstract. There is an increasing demand for autonomous sensor devices which can provide reliable data on key water quality parameters at a higher temporal and geographical resolution than is achievable using current approaches to sampling and monitoring. Microfluidic technology, in combination with rapid and on-going developments in the area of wireless communications, has significant potential to address this demand due to a number of advantageous features which allow the development of compact, low-cost and low-powered analytical devices. Here we report on the development of a microfluidic platform for water quality monitoring. This system has been successfully applied to in-situ monitoring of phosphate in environmental and wastewater monitoring applications. We describe a number of the technical and practical issues encountered and addressed during these deployments and summarise the current status of the technology.
