“…In recent years, the application of AFM to surface morphology studies of polymers has grown rapidly. It has already been used to study polyethylene, polypropylene, polyaniline, , polypyrrole, , methyl methacrylate, crystallized or polymerized in situ , and nylon films, to mention a few. Several studies on oxygen-plasma-treated polymer films have been conducted, for example, on the following: polypropylene, − poly(tetrafluoroethylene) (PTFE), and polyimide film .…”

Application of AFM on the Adhesion Studies of Oxygen-Plasma-Treated Polypropylene and Lignocellulosics

et al. 1999

Atomic force microscopy was used to study the surfaces of oxygen-plasma-treated polypropylene (PP), kraft pulp, filter paper, and wood. The effect of plasma treatment on the adhesion properties between PP film and wood was evaluated by means of a peel test. The highest adhesion to wood resulted from the shortest treatment times used. The effects of plasma on the adhesion properties were more pronounced when both the PP film and the wood surface were treated. Oxygen plasma caused changes in the morphology of the materials: the treated PP surface was covered by a nodular structure, which was not seen on the untreated film. A similar nodular structure was also seen on the lignocellulosic materials. These nodules seemed to have poor interaction with the PP surface, resulting in a weak interface between the plastic film and wood.

Synthesis and characterization of nylon 6 polymer nanocomposite using organically modified Indian bentonite

et al. 2020

In this present research work two different organic compounds are applied for the modification of Indian origin bentonite. One is with n-hexadecyltrimethylammonium bromide (CTAB), intercalated with an interlayer of bentonite via cation exchange mechanism. Whereas, another with 3-Aminopropyl trimethoxysilane (APTES) interlayer functionalization with bentonite-OH group. APTES and CTAB-intercalated bentonites samples were further cross modified with CTAB and APTES to obtain novel co-surfactant locked organo bentonite modeling (CLOM) like matrices. Original and modified bentonite samples were comparatively evaluated by advanced characterization techniques such as, powder X-ray diffraction, Fourier-transform infrared spectroscopy, thermal gravimetric analysis (TGA). Moreover, the applicability of the developed CLOM like materials were investigated in nylon 6 nanocomposite preparation by melt compounding method using a micro twin co-rotated extruder. Additionally, CLOM-nylon-6 polymer nanocomposites were characterized by wide angle X-ray diffraction, TGA, differential scanning calorimetry, atomic force microscopy and tensile strength measurement. The observed thermograph results confirmed no significant difference in the thermal properties of the developed composites. Whereas, the significant variation observed in the tensile strength results particularly for developed composite 5% of N6-OAMSB and N6 AMOSB 5 showed 111.5 and 76.6% respective enhancement in tensile strength results when compared with a bare nylon-6 polymer.

“…In recent years, the application of AFM to the surface morphological studies of natural and synthetic polymers has grown rapidly. It has been used to study the topographical changes occurred in cellulose fibers, [5 -16] synthetic fiber, [17,18] carbon fiber, [19] and various polymeric films, [20,21] from various methods including; grafting, irradiation, plasma treatments. The microscopic techniques have also been used to investigate the distribution of the grafted polymer in the fiber matrix.…”

Characterization of Poly (Methyl Acrylate) Grafted Bleached Sulfite Pulp Fibers using AFM, AEM, EDS and STEM

Sulfite pulp fibers were grafted by poly (methyl acrylate) at a low-consistency (1% pulp consistency) and medium-consistency (10% pulp consistency). It is of fundamental interest to determine the distribution of the polymer chains obtained at different fiber concentrations during grafting. In this study, modern analytical tools such as atomic force microscope (AFM), energy dispersive spectrometer (EDS), and scanning transmission electron microscope (STEM) were used for investigating the distribution of the polymer chains in the fiber matrix. AFM images in tapping mode showed that the fiber surface was covered with in-situ generated polymers. The X-ray mapping of Na in the cross-section of the hydrolyzed grafted fibers by using EDS in combination with Na line scans by STEM showed that the distribution of poly (methyl acrylate) was affected by the pulp consistency during grafting; at a mediumconsistency condition the outer region of the fiber structure had a higher polymer concentration than the inner region. On the other hand, at a low-consistency condition, grafting occurred uniformly across the fiber wall structure.
