Initiated chemical vapor deposition of antimicrobial polymer coatings

Thin Polymer Films with High Step Coverage in Microtrenches by Initiated CVD

“…[17] Decomposition of the initiator at an array of heated filaments produces radicals which initiate a free-radical polymerization of the monomer through its vinyl bonds. This method has been used to deposit a variety of polymers such as hydrogels, [18] alternating copolymers, [19] functionalizable materials, [20] antimicrobial films, [21] insulating organosilicones, [22] and sacrificial polymers for the production of air-gap structures. [23] In this work, we have deposited pCHMA using tertbutyl peroxide (TBPO) as the initiator.…”

A review of immobilized antimicrobial agents and methods for testing

“…Irreversible immobilization of the antimicrobial agents in the device offers an alternative motif that eliminates patient exposure to elutable active agents and potentially increases the duration of antimicrobial efficacy. 8,9 A wide range of antimicrobial agents have been immobilized, including small molecules (e.g., quaternary ammonium silanes), [10][11][12][13][14][15][16][17] quaternary ammonium polymers, [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] polyamines, [36][37][38][39][40][41][42] chitosan, [43][44][45][46][47][48][49] enzymes, [50][51][52][53][54][55] peptides, and peptide mimetics. …”

Biomaterials by CVD Methods, Introduction to the CVD Special Section

“…[14] Micro-patterned surfaces of poly-(acrylic acid) and poly(allylamine) were made using a mask and PECVD for use as bio-sensors. [15] Treating surfaces with anti-microbial coatings has been reported for initiated CVD of polymers, [16] through incorporating silver nano-particles by flame-assisted, atmospheric-pressure (FA-AP)CVD, [17] and UV irradiation of APCVD-produced TiO 2 ceramic coatings. [18] The recent works featured in this special issue cover a range of applications in biomedical, anti-microbial, and biomimetic areas.…”
