Surface modification of polycarbonate by plasma treatment

Cold plasma-induced surface modification of heat-polymerized acrylic resin and prevention of early adherence of <i>Candida albicans </i>

“…It is calculated by dividing the test force by surface area of contact, incorporating the plastic component of displacement. Results in this study showed that plasma treatment significantly increased surface microhardness, which could be attributed to the plasma-induced crosslinking phenomenon [36][37][38][39][40] . Thus, plasma would also be helpful in enhancing the etch resistance of denture bases 41) .…”

Physico-chemical characteristics of high performance polymer modified by low and atmospheric pressure plasma

“…Once the C=O bonds are formed, oxygen gets attached to such oxidized carbon atoms which leads to the forma tion of O-C=O species [10]. Qureshi et al [11] have studied the effect of nitrogen plasma on the surface of polycarbonate and have observed that the intensity of C-C/C-H bonds reduced with the increased inten sity of C-O/C=O bonds after plasma treatment. The change in surface chemistry of a polymer surface due to plasma treatment has been investigated in detail by several researchers [12,13] and their observation sup ports the findings of present investigation.…”

Photolithographic Patterning of 3D‐Formed Polycarbonate Films for Targeted Cell Guiding

“…[14][15][16] Common modifi cation methods of polymer substrates range from plasma treatment, [ 17,18 ] UV irradiation of the surface, [19][20][21] to chemical treatment. Furthermore, the good biocompatibility, the low manufacturing cost, and the infi nity of shapes into which polymers can be processed make these materials highly attractive for applications such as disposable biomedical microdevices.…”

“…Polycarbonate is a widely employed industrial polymer due to its high temperature and impact resistance, along with its transparency. [ 17,29 ] In the current contribution, we describe a general method for the spatially resolved functionalization of polycarbonate fi lms in the context of cell culture and guiding experiments. [24][25][26] Employing the SMART process, polymer fi lms are three-dimensionally stretched under mild conditions allowing to generate pre-modifi ed, fi lm-based microstructures, e.g., to generate instructive environments for cells which can partly recapitulate in vivo conditions.…”

[14][15][16] Common modifi cation methods of polymer substrates range from plasma treatment, [ 17,18 ] UV irradiation of the surface, [19][20][21] to chemical treatment. [ 22,23 ] Our current work focuses on a thin, precast polycarbonate fi lm, irradiated with swift heavy ions (gauge 65 µm, it4ip, Belgium).…”
