“…14 Unfortunately, a key disadvantage of using PDMS is its poor adhesion and bulk mechanical properties. 14,15 Thus, over the last few years, a significant effort has been underway to overcome these limitations using other polymers such as epoxide and polyurethane with PDMS. [14][15][16] However, it is hard to find the exact chemical composition of PDMS with polyurethane.…”

Waterborne polysiloxane-urethane-ureas (WBPSUU) were prepared through a prepolymer process using siloxane polyol, namely polydimethylsiloxane (PDMS) and polyether polyol, namely poly(tetramethyleneoxide glycol) (PTMG) as the soft segments. The goal of this study was to explore the potential use of polysiloxane-urethane-urea in marine coatings in order to boost the flexibility, adhesion, erosion, and foul-release property with respect to PDMS/PTMG ratio (PDMS wt%). The structural elucidation of the synthesized waterborne polyurethane and WBPSUU was carried out by FTIR, 1 H NMR, and 29 Si NMR spectroscopic techniques. The XPS and AFM analyses indicate that the polymer surface can be silicone enriched with the optimum PDMS content (15.76 wt%). The antifouling property of the coatings was investigated by the immersion test under a marine environment for 90 days. The fouled area was calculated for all the samples and the fouled area (%) decreased with increasing PDMS content. After 90 days the lowest fouled area (5%) was observed in the sample using WBPSUU4 (PDMS 15.76 wt%) among all of the samples.

“…Moreover, free standing films have some advantages such as easy operation and flexibility in practical applications for multifunctional devices. It is still a great challenge to develop free standing composite films based on epoxy resins since epoxy resins are strongly adhesive to various substrates [23][24][25]. Epoxy and its composite films can be prepared on various substrates [15,[26][27][28].…”

Abstract.A new method is reported on preparation of multifunctional free-standing Ni/epoxy composite films with comprehensive physical properties under an applied magnetic field. A water soluble poly(vinyl alcohol) film is used as an interlayer film to separate epoxy resin and glass wafer. Ultrafine Ni particles are incorporated into a self-designed flexible-type transparent epoxy resin to get composite films. For the purpose of comparison, random Ni/epoxy composite films are also prepared in the absence of the applied magnetic field. The aligned composite films are endowed with promising optical, mechanical, electrical, and ferromagnetic properties. The specific resistance is 4-9 orders lower in the vertical direction than that in the horizontal plane and the squareness ratio in the vertical direction is about 50% higher than in the horizontal plane. Meanwhile, their transmittance is much higher than that of the random composites. The anisotropies in their electrical and ferromagnetic properties are very useful material characteristics that may be explored for many applications.

Abstract. In order to resolve the problem of bubble defect after encapsulation, from the vacuum casting process requirements, the equipments were developed for the needs of production and scientific research. The development of the equipment adopts two schemes: final-mixed type and on-line mixing type. The equipment adopts compact design, automatic control, and easy to operate. The system functions of the prototype were tested and their technical indexes meet the design requirements. And the encapsulation parts encapsulated by the prototypes are tested to solve the bubble defect of the high-pressure module. Potting products have been detected, and it shows the two equipments effectively improved the bubble defects.
