“…For example silane plasmas are used in solar cells [10] and microelectronics [11], diamond-like carbon (DLC) coatings are used as hard, wear-resistant barriers for mechanical parts and biomedical implants [12], while soft functionalized plasma polymers may be used to attach biomolecules to surfaces for improved biocompatibility or drug delivery [13]. Recently, plasma deposition has enabled the convergence of technologies in the nano and micro scale range, including controlling interfacial bonding in composites [14], fabrication of nano-thin films for electronic applications [15,16] and microscale features to control protein adsorption [17].…”

Plasma enhanced chemical vapor deposition (PECVD) can be used to fabricate surfaces with a wide range of physical and chemical properties and are used in a variety of applications. Despite this, the mechanisms by which PECVD films grow are not well understood. Moreover, the species which contribute to film growth can be considered quite differently depending on the process. Particularly for functionalized plasma polymer films, the growth mechanisms are considered with respect to the chemistry of the depositing species, ignoring the physics of plasmas. Here we analyse the role ions play in the deposition of three common classes of depositing plasmas, and how these closely related fields treat ions very differently.

“…[5][6][7] They include electrochemical vapor deposition, 8) solution method, 9,10 monomer or oligomer chemicals, 11,12 plasma etching [13][14][15][16][17][18] and plasma polymerization coating method. [19][20][21][22][23][24][25] When the surface of natural fibers are modified by chemical methods, the interfacial properties can be efficiently improved, but the process needs somewhat complex steps of treatments including removal and recycling of the chemicals leading to additional process cost. Plasma etching and plasma polymerization coating techniques have been suggested as one of the most efficient and clean techniques to resolve the interfacial problems for reinforcing fillers including hydrophilic particles such as silica 26 and natural fibers like jute fibers.…”

ABSTRACT：A jute fiber surface was modified with argon gas in a cylinder type RF plasma generator to enhance the interfacial bond strength and to optimize the plasma treatment condition. The plasma power, gas pressure, and treat time were varied to figure out any effect of those parameters on the morphology and mechanical strength of jute fibers, and the interfacial bond strength for a model composite with polypropylene resin. As the severity of plasma treatment was increased, the surface of jute fibers became rougher. Gas pressure was less effective in roughening of the surface compared with those of treat time and plasma power. Approximately 25% drop in tensile strength of jute fibers was observed for the parameters of treat time and plasma power, while little deterioration was found for gas pressure, with increasing the severity. Based on the interfacial shear strength (IFSS), the optimum plasma treatment condition was determined to be treat time of 30 s, plasma power of 40 W, and gas pressure of 30 mTorr. 요 약：계면접착력

“…In traditional fiber-filled composites the interfacial region is critical to control the load transfer from the matrix to the fiber and thus critically influences both the modulus and fracture behavior of the composites. [1][2][3][4] However, in nanotube filled polymers, the interfacial region can be quite significant. A number of researchers have taken composite interface as a medium phase (interphase).…”

Static tensile tests, dynamic mechanical analysis as well as electron microscopy were used to characterize the macromechanical properties of MWNT-filled polycarbonate composites. Meanwhile the behavior of the nanotube/polymer interfaces was examined by changing nanotube contents and measuring electrical conductivity and dielectric spectroscopy. When the interface achieved the state of percolation (2 mass% MWNT), strain of fracture of MWNT-filled polycarbonate composites reached a peak of 9.3%, elastic modulus increased 30% comparing to pure polycarbonate and damping ratio bottomed out.
